Docker Tutorial for beginners - Complete One Shot

Hi everyone, and today's session is going to be a complete one-shot Docker lecture, within which we will cover Docker and Docker-related concepts end-to-end, in detail, and in-depth, with the help of a lot of practical examples and real-life use cases. By the end of this lecture, we will be able to master Docker, and we will fully understand how we use Docker in our own software development process.

Now, along with this, all the important Docker commands that we will cover within today's lecture will all be available to us in a single PDF, the link to which you will find in the description box below. If you want, you can also download it. If we talk about the index of the lecture, these are all the concepts that we will cover in today's session.

We will start by understanding what exactly is Docker and why we use it. We will get to know the difference between Docker images and containers. We will cover all the important Docker commands, the difference between Docker and a virtual machine, how to set up port mapping or environment variables, how to troubleshoot containers. We will also understand the Dockerization of our own application with the help of a Dockerfile. How we manage multiple containers with the help of Docker Compose. How exactly does layering work in Docker images? What is volume mounting? What is Docker networking? We will also cover Docker networking in-depth, within which we will also build our custom networks. So, today's lecture is going to be crucial for all working software engineers who want to learn advanced development concepts or maybe transition to a DevOps role. So, let's start with our Docker one-shot.

Now, we are going to learn about Docker, which is an essential tool, especially when we are working with large organizations and large development teams. Before we start learning about Docker, it is crucial to understand why exactly do we need it. What are the issues, what are the problems in our current software development process that Docker had to come to solve? For that, let's take a very basic example. Let us suppose we are somewhere, and we are trying to develop a Node.js-based application. So, there is an application that we are developing. Now, generally, if we are building a Node.js application, we would have already installed Node within our system. Let's assume to install Node, we have installed version 16 of Node. Along with that, we are also using MongoDB as a database, so for that, we have installed version 4.2. So, this is our local development environment within which we are building our application.

Now, whenever we are talking about personal projects, or if we are talking about small-scale projects, then generally we do not encounter that many problems. The problems that Docker comes to solve are generally encountered within large organizations, or when there are many members in our team, and all of these members are working on the same application. Then generally, these problems are encountered. Let's assume we are also working within a team in an organization, and a new member joins. So, this is our new team member who has a Mac OS, and now they want to replicate this entire setup into their own system so that they can also work on the same application. So, this member is going to manually install all of the dependencies one by one.

So, it starts with installing Node. We have installed Node. It's possible that a newer version has come out, so we have installed version 20. In a similar pattern, we installed MongoDB. So, it's possible that there is also a newer version of it, so we have installed version 6. And in this way, we have set up this entire setup into a different machine. Now, when we try to replicate the local development environment of one machine into another machine in this way, then there are some common problems which we can encounter. The most common problem among these is that we are installing dependencies one by one, one by one, manually in the new system. So, in that case, there can be many manual errors. Here, we have taken a very basic Node.js application example, but a real-life application will have lots of dependencies, and there is going to be a lot of error in manually installing so many dependencies.

Along with that, the second common error that can occur is that it's possible that a specific part of our application depends on a specific version of Node.js, and here, if it doesn't find the same specific version of Node.js, then in that case, there could be some bugs that occur within our application. Another common problem might be that if we are using some CLI commands in our application that are used in the original application, and these commands are working on the same thing, and we try to recreate or replicate the same thing on the production server, then there are also chances of these same common errors occurring there. And this is a problem that if there are two people in our team, four people, then it is very easy to solve. But when we talk about larger teams where many members are involved, and all of them are working on the same application, then in those cases, our development process can become quite error-prone.

Now, this gives rise to a very classical problem in software development which is called "It works on my machine." And to solve this specific problem, tools like Docker became necessary. When we talk about Docker, if we want to understand Docker in the simplest terms, then it is basically a platform that helps us build containers. To understand Docker, it is very important to understand two words, two terms: one is Docker container, and another is Docker image. If we understand the meaning of both of these, then we will have complete clarity on what exactly Docker is and what it does.

First, let's talk about what exactly a Docker container means. Now, we know that Docker helps us build containers, but what exactly is this container? A container is basically a single bundle, a single unit, in which we have combined or packed our application along with its dependencies into a single unit. Now, our individual dependencies are not individual units. Now we have packaged our application and all of the dependencies into a single unit, and this is the single unit that we will be sharing with our teammates, and this is the single unit that we are going to deploy.

So, it's very simple to replicate. For example, if we are on machine A, and we want to replicate the environment to machine B, then we simply need to create a bundle of our application and dependencies, and we can share this single unit from our machine A to our machine B and set it up there without installing or setting up all the dependencies individually. And the best thing about these containers is that now, irrespective of the machine's operating system, whether machine B has macOS, they will run there. So, containers are basically a standardized way to help share our application with its dependencies, basically replicating the entire development environment in a standardized way across a large team.

Now, when we talk about containers, there are some specific properties which are associated with containers. The first property among these is being portable. Being portable means a container as a unit can be shared across teams. Now, whenever we are talking about sharing, in technical terms, we don't exactly share a container as a container. Instead, to share a container, we share a Docker image, and this is something that we will be learning gradually within this lecture. So, being portable means our container can be shared with different systems, different machines.

The second property of a Docker container is that it is lightweight in nature. Being lightweight in nature means it has very less overhead, due to which it is fairly simple to create these containers, to update containers, to have multiple containers on a single machine, as well as to delete these containers. So, the entire process becomes simpler because the size of our Docker images or Docker containers is very small as compared to something like a virtual machine.

Along with this, Docker containers give us another major benefit, and that is, let's suppose this is our local machine on which we want to build two applications. Both of the applications are going to be Node.js applications. So, for that, if our machine has version 16 of Node, then we know that here also, our application will use Node version 16, and here also, Node version 16 will be used. But if we need a use case like this where we want to build two separate applications, one in which we want to use version 16, and one in which we want to use version 20, then to create such a setup on a single machine, we can use our containers. Basically, we will build our first application on container one, and the second application on container two. So, our containers, in themselves, carry a separate environment as compared to the host machine. So, on the host machine, there might be any version of Node.js, but within the containers, we can use another version of the same technology, the same dependencies. And in this form, we can build multiple apps in parallel with different versions of the same dependency.

So, this was all the fundamental knowledge about Docker containers. We are going to study Docker containers in a lot of detail within today's lecture, but before that, let us also talk about Docker images. Now, this Docker image is not exactly an image or a picture. This is basically an executable file. It is a file that contains instructions for building a container. So, the job of a Docker image is to build containers. Basically, the relationship between a Docker image and a Docker container is the same as the relationship between a class and an object. If we talk about the relationship between a class and an object, what do we say? A class is a blueprint that helps us create multiple objects. Similarly, we can say that a Docker image is a blueprint that helps us create multiple containers. Just as multiple instances can be created from a single class, multiple objects can be created, similarly, if we have a single Docker image, which is an executable file, we can create multiple Docker containers from it. So, generally, when we share our application plus dependencies with our team members in a big team, we don't share containers; we share images. This image goes into everyone's separate system, and everyone creates a container from this image within their local system.

The second difference between an image and a container is basically in terms of resources. For example, the class we create in object-oriented programming, the class itself does not occupy significant storage in memory. The storage occupied in memory is through the object because objects have their own properties, their own details that they need to store, which can take up a lot of storage. So, actually, between class and object, who uses the resources? Our objects use them. Similarly, our containers use the resources of our system, not our image objects. So, the size of an image is generally very small, and when we create a container from an image, the entire running environment is set up within the container, due to which our container is using the computer's resources.

So, to summarize, a Docker container is an actually running instance, whereas a Docker image is a static snapshot or a static screenshot of what the local development environment should look like. So, this was the basic difference between a Docker image and a Docker container, and this difference will become super clear to us as soon as we run our Docker commands.

Now, before we start learning Docker commands, we are first going to look at a very practical example of Docker, which will give us complete clarity on what exactly Docker is. What we will do is, we have a host machine now, we have our own macOS system. Within this macOS, let us suppose, for example, we want to run a container. We will cover this in detail. For now, we can understand its meaning as: with the help of this command, we will run an Ubuntu container within Docker or within our machine in interactive mode. Interactive mode means where we can access its terminal. So, here, we are talking about the terminal of the Ubuntu machine. So, as soon as we run this simple command, first of all, we are getting the message that "This image was not available locally." So, it will be fetched first. First, Docker checks if the image we are bringing, from which the container will be built, is available on the local system. If it is, then it will be taken from local; otherwise, it will be fetched from this platform which is called Docker Hub. So, here the image has been downloaded, pulled, set up, and now a complete container has been created from that image. How will we know that a container has been created? We have an application called Docker Desktop, which we will install later. So, there, in the Containers tab, we will see that this container is now there, and this container is made from which image? It is made from the Ubuntu image. This container is currently running. This is the ID of this container, and if we look here, it is the same ID within which we are sitting right now. We are inside the root directory. Here are the files and folders of our system. Here, no new directory has been created. It has been created for us. So, what we did here is, the files and folders that we will create now within this Ubuntu machine are completely separate from our Mac machine. So, basically, now we are inside this Ubuntu container, within which we can add some new files if we want, we can delete old files if we want. Whatever changes we make inside this Ubuntu container are completely isolated from our Mac operating system. Tomorrow, if we want, we can delete the entire container; it will not affect our macOS. So, here we have taken the example of a simple Ubuntu container, with which we first downloaded the Ubuntu image from the internet, and then created a container from it. And this is that container within which we are.

What is the difference between a virtual machine and Docker? But Docker is quite similar to a virtual machine, but it is much lighter in comparison, and doing such things is very simple with Docker. For now, we have only run an Ubuntu container. Later, we will see how we can run different containers for MySQL, for MongoDB, and use these particular technologies for our development purposes.

Next, we are going to set up Docker on our local system. Now, to set up Docker, we can visit this link, which is docker.com, and from here, we have to download something called Docker Desktop. Now, depending on our machine, whether we are on Mac or Windows, we have multiple options available. So, we can simply visit docker.com, and here we have this big blue button, and we can download Docker Desktop depending on whether we have Intel or Apple chip.

Let's proceed with the download. I am on Windows, so I will click on this. And now, finally, Docker has been installed on our system. We can also see it within our applications. So, Docker is now available. To verify from the terminal CLI, we can rerun the Docker command, and now all of these options will be available to us. We can also check the version of our Docker with the help of `docker --version`. So, we have version 27.5.19.

There is an option to download Docker Desktop, where we are going to select Windows AMD64, and the download process is going to start. As soon as our download is complete, we will click on our installer, and the installation for us will start. We need to click on "OK." As soon as we click on "OK," all of our files will start unpacking, basically, the installation process of Docker Desktop has started. Now, during this installation process, it's possible that Docker will ask us for permission to run as an administrator and to be able to make changes to our files. So, there, we have to accept, and we have to give the required permissions to Docker. As soon as the installation is complete, we will get an option to "Close and Restart." We are going to click on this button, and our system will restart.

After the system restarts, we will get to see this window on our system. Now, if this popup does not appear, then in that case, the Docker Desktop icon will already be on our desktop, so we can also click on Docker Desktop. So, this popup will appear. We are going to accept the agreement.

To set up Docker Desktop, we have two options: either the recommended settings, or we can set our advanced settings ourselves. We are going to move forward with the recommended settings, and we are going to click on "Finish." As soon as we click on "Finish," some basic login details might be asked from us. So, either we can sign in with our work or personal email account, or we can also skip this step. So, we are going to click on "Skip." There are some basic options that we can answer. We are going to select "Full Stack Developer." We are going to continue again, and after continuing, finally, our Docker engine has started.

Now, on Docker, we can see the different options in the left panel. At the top, we have containers, then we have images. So, all of our Docker images, Docker containers that we will create, will all be visible to us on Docker Desktop.

Now, to check if Docker is successfully set up on our system, we can also check from our command line. We will search for CMD and open the Command Prompt. So, within the Command Prompt, we can simply type the Docker command, and with that, all of our Docker commands will appear. If the Docker commands are appearing, then in that case, Docker has been successfully set up. So, if Docker commands are printing, it means Docker has been successfully set up. We can also see the version of our Docker. We can simply write `docker --version`. So, it will show 27.5.19.

All Docker images will be displayed. For now, I have deleted all of my images and containers, but this is how the...

Docker Desktop is going to look like. We can also verify via terminal if Docker is successfully set up on our system or not. So for that, we will run this command called `docker -v`. Like, the version of whatever Docker we have installed will come. Along with that, we can also run this command called `docker`. With this, all the Docker commands will be printed for us. Now we are finally going to start dealing with images and containers. Now, just like for applications, we have Docker Desktop, similarly, we have one more important website which is called Docker Hub. Until now, we would have used GitHub. GitHub basically is a collection of all of our code where we have our different repositories and we push our code. Similarly, the public collection of Docker images is available on Docker Hub. To go to Docker Hub, we can simply go to this link `hub.docker.com` and by going here, we can access multiple public Docker images. So next, we are going to start learning about Docker commands. Now, before using Docker practically, there are some basic commands of it that we should have a good idea about. So we will practice these commands with the help of different images and different containers. For that, we are going to start with a very simple image called "Hello World". This is kind of the official Docker image with which we start learning Docker. So first, we will take the "Hello World" example. After that, we are going to increase the complexity of our images. Later on, we will take the Ubuntu example, the MySQL example, the MongoDB example, and we will practice our Docker commands on multiple Docker images and containers. For example, we will start with this image called "Hello World". So this is the "Hello World" image with which we are going to start. Generally, if we go to any image on Docker Hub, there are some tags associated with the image. What exactly these tags are, we will learn about them gradually within this lecture. Along with that, for every image, its basic documentation is given, which we can read. There might be some example output, there might be different environment variables that the container needs. So different things are associated with each image. Now, to bring any Docker image from Docker Hub to our local environment, we need to make use of Docker commands. Among these, the first and most basic command is the `docker pull` command. We write the name of any image, and if this image does not exist in our local environment, it will be pulled from Docker Hub. So, for pulling, we already have the command given: `docker pull hello-world`. Let us just copy this command and paste it here simply, and we are going to run this. So here we are getting "default tag: latest", which means that we are going to have the latest version of this image. And we have successfully downloaded the newer image for "Hello World". How can we check which Docker images we have? We can simply run the `docker images` command. So, currently, we have a single image, which is "Hello World", existing. There are some tags associated with this image. Tags are basically the versions of our image. Just like different versions of any technology like Node exist, similarly, we can create different versions or different variants for Docker images. If we want to see this image in our Docker Desktop, then we can simply go to Images, and this image has been created for us here automatically. For an image, there is also an image ID that gets associated with it, a unique ID. And if we look at the size of this image, then this size is literally in KBs, meaning the image size is very small. And that is why Docker is called a very lightweight technology. Now, to create a container from this image, because we have already learned, once a Docker image is available, we build containers from it. So, to build containers, we have the `docker run` command. We can basically build any of our containers from any image. So, to build a container from an image, we use `docker run` and then the name of our image. So, a new container will be created for us automatically. So, here, if I write `docker run` and then the name of our image, which is "hello-world", then this is how a container was created and executed. The container executed means our container ran and printed all the things on our screen. We can also see this in Docker Desktop. We will go to Containers, then here is this new container that now exists. By default, Docker automatically gives any container a random name. Along with that, containers have their own unique ID. We can check which image they were created from. And in Images, now there is this green dot which signifies that using this image, there is some container that we have built. Now, what exactly did this container that we ran print? Basically, the entire process of creating and executing a container from any image was printed for us by our "Hello World" container. How? So, to generate this message, Docker took the following steps: First, the Docker client contacted the Docker daemon. Whenever we say Docker daemon, it is the core, the most important part of Docker Desktop, which does all the work for us. The Docker daemon pulled the "Hello World" image from Docker Hub. After that, the Docker daemon created a new container from that image, which runs on the executable that produced the output you are currently reading. So, from our "Hello World" image, our container was built, then our container ran, and by running, it printed the output for us. We can do the same thing if we want with another image. Here, we have been given this suggestion to run this Ubuntu image. So, let us clear this. And in fact, if we want, we can also go to Docker Hub and search for Ubuntu. So, we will get the official image of Ubuntu. With the `docker pull` command, only the image is pulled. Whereas if we directly do `docker run`, then the image is also pulled, plus a new container is also built from it. Like here, if I copy this, then I will pull the Docker Ubuntu image. And the image is successfully here. If we see in Images, then we have successfully created the Ubuntu image. And from this image, we can simply do `docker run ubuntu`. Now, before running our container, we are going to use a special option, which is the `-it` option. Basically, we can run our Docker containers in interactive mode. What is interactive mode? This mode basically allows us to access the container's terminal, which helps us input or output anything. So, here, after `run`, we can simply use `-it`, and in this way, if we run our command, then we have now gone from our host terminal, i.e., the Mac terminal, to the Ubuntu container's terminal. Here, we can see that we are in the root directory. And by typing `exit`, our container ID will be printed for us. In fact, we can also verify this by going into Containers. This is the Docker container which is running right now. The previous container is in its stopped state, whereas this is a container that is currently running. And if we match its ID from here, then this is the same ID. So, currently, we are inside the container of the Ubuntu image, and this container has its own separate environment. Inside this container, we can separately go and run multiple commands. For example, we can run the `ls` command. So, these are all the files and folders that exist inside our container. If we want, we can create a new directory. Let's suppose we create a directory. The directory has been created. If we want, we can print the different environment variables. So, we will get all of this information. And finally, we can `exit` from here. As soon as we exited, our container automatically stopped for us, and now it has gone into the stopped state. Whenever we want to see how many containers we have, then we can run a simple command, which is `docker ps -a`. With `-a`, meaning all, we can check all containers. So, these are two containers that we had created. Currently, both containers have the status "Exited". By default, they have been given some name, and we can also see the IDs of these containers. If we want to see running containers, then for running containers, we run `docker ps`. Since currently no container is in its running state, no container will be printed for us. Now, just like we have the `docker pull` command and the `docker run` command, similarly, there is another important command for us, which is called `docker start`, and similar to this is `docker stop`. Whenever we run the `docker run` command, we always create a new container from any image. Whereas with the `docker start` command, we can start any existing container. So, to start a container, we use `docker start`. After `docker start`, we either have to write the name of our container, or we can use the container ID. As soon as we started, then this time, if we do `docker ps`, then we now have a running container that has just started. And we can also verify by going to Docker Desktop. This green dot means that it is in the running state. If we want, we can also stop it. We can do `docker stop`, and this time we will try to stop it by its name. Now, if I do `docker ps`, then now no container will be printed for us. In this way, we can start and stop our containers. Now, along with this, there are also two more commands which are important. The first one is `docker rmi` command, which is used to remove or destroy any image. Another is the `docker rm` command, which is used to remove any container. For example, if we want to see our images now, then we have two images existing. For example, we want to destroy or remove this "Hello World" image. So, for that, we can simply do `docker rmi` and then the ID or the name of our image. When we run this, we get an error. And the error is "Image is being used by a stopped container". Basically, the "Hello World" image, we have already created a container from it. So, to destroy or to delete this image, we need to delete the container first. So, what can we do? From here, I can print all the containers. Among these, this is the container which is using the image. So, first, we will remove this container using `rm`, and after that, we are going to remove the image, which is "hello-world". And in this way, our image has been deleted. Let us clear it. And now, if we print in `docker images`, then our image has been deleted. With `docker ps -a`, we can also look at the other container, and we can also delete this container. `docker rm` and `docker rmi ubuntu`. And in this way, we have now deleted all of our containers and all of our images. Next, we are going to learn about versions in Docker images. Now, if we go to a new image, let's suppose now we want to pull the MySQL image. So, this is the MySQL image. Now, with the MySQL image, there are a lot of tags which exist. We have already talked about it, a tag is like a version or a variant of the same Docker image. So, generally, if we simply do `docker pull mysql`, then here we have pulled the latest version of the MySQL image. If we want to pull MySQL 8.0, then for that, we can write `docker pull mysql:8.0`, and in this way, we will get a different image, in which now we have a different version. These things that are being downloaded one by one, on each line, these are basically the layers of an image. Images have different layers. We will discuss these in detail later. So, when we are using multiple versions of the same image, then some layers are common within those images. So, if one version has already been set up on our system, then when we set up the second system, it is written for us that "some layers already exist on the host machine". We have also seen an example of this. If we want, we can see it again. So, for that, let us remove this MySQL latest image. So, for that, first of all, let us stop the running container. This is the container ID. After that, we can simply remove the container. And in Docker Images, we will simply remove our image, which is `mysql:latest`. Now let us clear it. And now we have only one running container, which is the MySQL older version. And in Images, only that image exists. Now, if I do `docker pull mysql` (the latest version), then the different layers of this image will be downloaded. Now, for some layers that already exist, it will be written "already exists". But the remaining layers that differ between the two different versions, those layers will be separately downloaded onto our system. So, this is the download process for the different layers, and the ones that were the same already existed on our system. Let us clear this. And we can run a separate container out of it. So, for the container, we will run this command, in which this time we will give a name to the container.

Here are the MySQL latest, let us enter it, and in this way, now we have two running containers. One is MySQL latest, and one is MySQL older. Next, we are going to talk about an important concept which is called port binding. What does port binding basically mean? Whenever we have a container created, by default in Docker, by default all Docker containers have a port which is bound to them. Along with that, all Docker containers have a separate virtual file system, which we have already seen, that the files inside each container are separate files as compared to the host machine. Similarly, the ports of the container are also separate as compared to the host machine. For example, let us suppose we have this way, this is the machine on which we are working, and inside it, we have set up a Docker container. Now we know that our machine has different ports that can exist, like 8080, 5000. Similarly, our container also has some ports that are already bound by default. For example, if we look at our Docker containers, for the MySQL container, what port is given to us? 3306 TCP. For MySQL older, what port is given? 3306 TCP. So basically, looking from here, it seems that the same port is bound to both containers, but that is not exactly possible. Here, when we are on the same machine, we have created two containers on our machine. This could be our older MySQL, this could be our latest MySQL. Now for both, our port shows 3306. So here also, we have 3306, here also, we have 3306. These two ports are not ports of the host machine. Our Mac OS, these are not its ports. These are related to this container, meaning container ports. Our host machine and the container's ports are separate in nature. But if we want, we can bind them with each other. Whenever we want a request to come on our port and that request to be forwarded to this port of our container, then we can use the hyphen p command to bind ports. So basically, we write hyphen p and after that, we declare the host port, which host port we want to connect with which port of our container, that is what we can define. So if we want to connect this 8080 to 3306, then we can simply write hyphen p 8080 colon 3306. So with this, whatever new container of our MySQL is built, our this port will be mapped with this port. So basically, whenever we map the port of our host machine with the container port, this process of mapping is called port binding, and this mapping process is very important. For example, here we have not bound any port of the local machine. So for now, let us delete these two instances. Let us do Docker stop for maybe MySQL latest, and after that, we are going to remove MySQL, MySQL latest. Similarly, we will do Docker stop MySQL older, and we are going to remove MySQL older. Let us clear this. Now, if we look at our containers, we don't have any containers existing. But we have these two images that exist. Now, from these two images, we will create two new containers with port binding. To create a container, we can simply write, or in fact, let us bring back our command. So this was the command that we had already written for our MySQL latest. So here, for port binding, we can simply write hyphen p, after that, we want our host machine's 8080 to be bound. Let us enter it. And now, if we do Docker PS, now our local host's 8080 is bound with 3306. We can do the same thing for our older version. So here, for 8.0, we can simply write, this is MySQL older. As soon as we run it, we will get an error. This basically says, pending for 8080 failed because the port is already allocated. Now this is very important. 8080 is the port of our host machine. If it is already bound with this container, we cannot bind it with another container. If we want to bind it with another container, then for that, we will have to bind a different port of the host machine. Seeing these two same ports, sometimes beginners get confused, but we should not get confused here. Whenever we are binding different containers, then there should be binding with different ports of the host machine. For example, here, we can do the binding with local host 5000, maybe, and a container was already created with a different binding, maybe 3000. And in this way, now we have two Docker containers that are now bound with different ports. The container port is the same, but the local host machine ports are different. So this is what port binding is. After this, next we are going to talk about some troubleshoot commands. Now, whenever we run Docker containers, there might be some errors in between. So to check these issues, these errors, there are some troubleshoot commands that we can run to check these errors. Among these, the most common command is the logs command. By writing Docker logs, we can access the logs of any specific container using its container ID or container name, which can help us identify the problem. So, let us try to access the logs of our MySQL latest container. So, we will write Docker logs and then the container name. So, in this way, we will get all the logs of the container. So, here, the container logs are starting from this line, which says initializing database files. So, in this way, our database is being initialized. Here, the initialization process of our MySQL was done, and then the MySQL server started. So, in this way, all the logs are there, which we can check. These logs can also be accessed in Docker Desktop. For example, for MySQL latest logs, we can just click on the name, and in this way, we will be able to access all of the logs. Along with this, we have one more command. Let us clear this, which is called Docker exec. The exec command basically allows us to run additional commands on an already running container. If a container is already running, and we want to access the terminal inside it and run more additional commands, then we can simply write exec and in interactive mode, we can access the bash or shell of that container. It is not necessary that bash exists inside every container. So in those cases, we have an alternative to access the shell of the container. So for that, we run this command. Basically, by accessing the terminal of the container, we can check the environment variables, we can check the files, we can check the different dependencies that the container has. So let us do that. We can simply write Docker exec hyphen i t, after that, the container name or container ID, let's take MySQL latest, bin bash. Enter. So in this way, now we are inside the container's bash. So here, we can run our commands. There is the ls command. We can check different environment variables if we want. In environment variables, this is the root password, which we set up as a secret. We have the working directory. There are many things that can be checked. We can simply exit this. Let us clear it. So when we exit from the last command, it does not stop our Docker container. The container is still running, but we have come out of that interactive shell, that interactive bash. So in this way, we can run troubleshoot commands for any Docker container. Next, we are going to analyze the difference between Docker and a Virtual Machine. So far, we have done quite a lot in Docker. How images are built, how containers are, how image layers work, we have explored many things. But now we want to explore the fundamental difference between Docker and a Virtual Machine. So let us try to understand this difference. Whenever we are on any machine, whether it is a Windows machine, Mac machine, or a host operating system, there is a kernel, and on top of it, there is our application layer. And on the application layer itself, all the apps within our system are present, like our browser. Docker uses the host OS kernel and virtualizes only the application layer. But if we talk about a Virtual Machine, then a Virtual Machine virtualizes both the host OS kernel and the application layer. Because Docker only virtualizes the application layer, that means Docker has less overhead, and because of this, our Docker is lightweight, and that also translates to Docker being faster and smaller in size. Whereas in a Virtual Machine, the sizes can be in GBs. So this is the basic difference between Docker and a Virtual Machine. Now, this is the major advantage of Docker, but along with this, Docker also has a major disadvantage. Whenever we talk about Virtual Machines, Virtual Machines are compatible with all underlying operating systems. Because VMs virtualize the host kernel itself, it does not matter which machine we are bringing the VM on. Eventually, the Virtual Machine will use its own kernel. And here, Docker's slight disadvantage is because Docker was initially built for Linux. So, for example, if we are on Windows, and we want to run a Docker container, then we will have to install Docker Desktop, which will install a Linux VM in the background. And then, on top of that Linux VM, our Docker will run. So, this is the reason why Docker is not directly compatible with Windows or Mac OS. However, Docker has made significant improvements in this area, and now it is possible to run Docker containers on Windows and Mac OS as well. But the underlying mechanism is still the same. So, this is the basic difference between Docker and a Virtual Machine. Now, let us talk about the next topic, which is about the difference between Docker and Virtual Machine. We have already discussed the advantages and disadvantages of both. Now, let us talk about the use cases. When do we use Docker, and when do we use Virtual Machine? We use Docker for microservices, for containerization, for deploying applications quickly, for scaling applications. We use Virtual Machine for running different operating systems on the same hardware, for testing different operating systems, for running legacy applications that require a specific operating system.

The binding has been done. In a similar way, we can run our second container, which will be based on Mongo Express. So, Mongo Express is basically an admin interface to connect with a MongoDB database. Once we set up both of these, we will also clearly understand the exact difference between Mongo and Mongo Express. So, to run this here as well, we are going to use similar options. For Mongo Express, we need to do port binding for port 8081. So, first, let's run the same command: `docker run -d`. Here, the port binding will be for 8081, so we are using the same host and same container port. After that, we can define its name as `mongo-express`, and we will create it or we will run this container in the same isolated network, which is `mongo-network`, which we have created. Now, for Mongo Express, we also need to define some environment variables. There are three environment variables that we will be using. If we go into the documentation, there are two environment variables: our `adminUsername` and `adminPassword`. For both of these, we need to enter the same username and password that we entered for Mongo, which was `admin` and `qwerty`. So, let us copy this from here. You can also type it on your machine. So, here we will define `admin`, and similarly, `admin-password`. So, here we are going to define the password. Now, whenever we are using Mongo Express, we need to define one more additional environment variable, which is called `MONGODB_URL`. So, this `MONGODB_URL` needs to be defined. This is something which is not updated in the latest documentation which is available on Docker Hub. Depending upon when you are watching this lecture, it is possible that in the future, that documentation might be updated. But for now, this `MONGODB_URL` environment variable is not in the latest documentation. So, basically, we need to define this URL, which will have our format for the URL. We need to write `mongodb://`, followed by whatever admin username we have defined, for example, for us, that admin username will be `admin`, and the password will be `qwerty`. We will write `@`, then `mongo` (if we have given our Mongo container some other name, for example, if someone has given their Mongo container a name like `mongo-new` or something like that, then here, instead of `mongo`, we need to write the name of that container), and then `:27017`, which is the port for Mongo. So, let us define this environment variable, `MONGODB_URL`, within which we are going to set up this URL: `mongodb://`, followed by our username, then our password, `@mongo:27017`. And finally, we can write the name of our image, which is `mongo-express`. So, let us enter it. And since `mongo-express` was not available locally, that image is being fetched again, all its layers are being pulled, downloaded. And now, let us clear this and do `docker ps`. So, now we have two running containers: one is our `mongo-express`, and one is our `mongo`. We can connect to our `mongo-express`, which is actually the user interface for MongoDB, which is available on `localhost:8081`. To connect to it, we can simply go to `localhost:8081`. If this sign-in option is appearing, it means `mongo-express` is working successfully. Now, the username and password that we need to enter here is different from the username and password that we had set. Here, a standard username and password will be entered. For the standard username, we need to enter `admin`, and for the password, we need to enter `password`. So, `admin` and `password`. As soon as we sign in, we will be able to see this window. This is basically the default setup for a MongoDB database. So, now we will understand that the MongoDB database, which is working inside the Mongo container, is our database. But what `mongo-express` is doing is giving us this graphical user interface, through which we can see that database in the form of this beautiful interface, which is very different from the terminal view. Now, we already have three databases here, which are created by default. If we want to create our new database, we can create it from here. Since we had defined our `college-db` database in the code, i.e., in our Node.js application, we are going to create this same database here. Here, we will write our `college-db`, and let us create it. So, our new database has been created. Inside this database, we can also create a new collection. We are going to create a new collection called `users`. So, let's create this as well. These are things that are already predefined. We had already decided that this will be the name of our database, this will be the name of our collection. If you want something custom according to your own needs for your Node.js application, then you can make changes to this sample code and accordingly, you can create your own database and your collections. We can also create a new document inside our collection. We know that inside our document, we need to have an email. So, for the email, let's assume an example: `gen@example.com`. For the username, we want to give `gen-doe`, and for the password, we are going to keep it `secret`. So, in this way, this is a sample document that we want to add. So, this sample document has been added for us. So, all the tasks that we could do from the terminal, now we can also do them from this interface. Now, if we want to check whether our database has automatically connected with our Node.js application or not, for that, what we can do is execute our GET request. Basically, we will send a request to `GET /users`, so that we get all the users' data. To check that, we are going to send a request to `localhost:5050/users`. As soon as we enter, we have a single output, which is this output. That is, the document that we added here, that same document is visible to us on this page, on this route, even though we have not set up any MongoDB on our local system. Our Node.js application is able to connect with the MongoDB database that is running inside the container. If we want to imagine this a bit more, then basically, in the setup that is currently running, this is our Node.js application or our test application, within which we have this file called `server.js`. Now, this `server.js` file is trying to connect with our database. So, to connect with the database, what we have done is, this is our Docker environment, within which we have this container, which is the `mongo` container, and similarly, we have created another container, which is `mongo-express`. So, now, if our `server.js` needs to fetch data or add new data, then it is basically interacting with the MongoDB database running inside this `mongo` container. Data is being fetched from here, data is being sent here, and all those changes, we can see them in the `mongo-express` user interface because they both interact with each other since they are in the same Docker network. So, this is the kind of setup that we have created, which is basically a practical example of how, if we are building any application, it is not necessarily specific to Node.js applications. Whether we are building Python-based applications, whether we are building on Golang, whether we are building on .NET, if there is a specific service for which a Docker container, already a Docker image, is available, then we can use it in this way without actually setting up that particular technology on our local system. We can also test with POST requests, for example, here, this is the home page. I can give `gen@example.com`, and here, a sample name can be seen. We can keep the password the same if we want. Let us create this account, and as soon as we come here, let us refresh `mongo-express`. So, our new user data will be entered. If we send a request to `GET /users` again, then we will basically get two users now. So, all our new data that we inserted is also available to us. So, in this way, GET requests are also working, POST requests are also working, meaning we are successfully connected with our database. So, this is the first use case when we can connect our Docker containers with any of our applications to use a particular technology inside our existing application.

Now, let's talk about the next tool, which is called Docker Compose. Basically, whenever we run multiple containers, for the ease of running those containers, for the ease as a developer, we have an additional tool available, which is called Docker Compose. So far, the task of setting up multiple containers that we have done with Docker commands, we haven't faced any problems as such, but Docker Compose makes that task a little easier for us. What exactly does Compose do? Basically, so far, we have run our container in this way. Whenever we run our container from the command line, there are different options with the container, either port binding is happening, or we are defining a custom name, there are some networks, there can be many environment variables, and there can be multiple other things that we define with a Docker container. Now, the process of running a Docker container in this way is quite complicated. If there are multiple containers, then the process we saw for Mongo and Mongo Express, we can convert all these commands into a single file. This file is a YAML file, in which we can basically convert and write all our Docker commands, and instead of running containers from the terminal, we will now run them from this file. So, YAML stands for "Yet Another Markup Language," and by running our commands from a file, there are basically two benefits for us as a developer. The first is that all the Docker commands we need to run are available to us in a very structured, standardized way. And the second benefit is that whenever we need to make edits to this file, it is very easy to do so. For example, if we want to set up something else instead of the password in this `docker run` command on the terminal, it would be a difficult process. As a developer, it won't be very smooth. But if we can edit in a file, then those are quite easy changes. So, we run this file with the help of Docker Compose. To use Docker Compose, we will create a YAML file and then use our Compose to run our containers from this file. So, it is basically a tool for defining and running multi-container applications. Generally, Docker Compose makes sense only when we have multiple containers, which is every application in a practical scenario, because generally, when we take examples, we can deal with a single container, but if we take the example of real-life practical applications, then multiple containers are running together there. So, there, Docker Compose is very helpful as a developer. Now, let us see what exactly we do in Docker Compose. Basically, so far, if we had to set up our Mongo container, then for that, we wrote all these Docker commands on our terminal. Docker Compose does this: it tells us that we don't need to write these commands anymore. This entire setup, we will now write it in this file. We can give any name to this file. This is a .yaml file, in which we define our entire Mongo setup in this way. So, in the YAML file, at the top, we define the version, which is basically the Docker Compose version that we want to use. Now, in the latest versions of Docker or Docker Compose, this version attribute or this version option is somewhat obsolete. We are going to put our file inside the application, but we will have a warning in the latest version that this version is obsolete, and we can remove it if we want. All the containers that we need to run, we define them in the file as `services`. So, we define `services` in this way, and then one by one, we start writing our services. So, in the same way that we wrote our `mongo` service, we can also define our `mongo-express` service. If we need to set up something else later, for example, if we need to set up Redis as well, then in the same way, we will define our third service, in which we will define all the environment variables, ports, and all other things for Redis. Now, indentation is really important in the YAML file, so that's why we define everything with proper spacing, with a tab space. We write the name of the service that we want to define. Now, with each service, just like when we were creating this container, first, to create this container, we need to know which image we want to use. So, here we write the image that we want to use. Along with that, if we want to do port binding, then in our YAML file, we define our ports in this way. This is the host port, and this is the container port. If we have any environment variables, then we define them in the file in this way. So, we go on writing the value of each environment variable. Now, by comparing these two commands and the file, we will realize how easy it is to create our YAML file compared to this Docker command. In this command, let's say if we want to set up a URL or something else instead of the password, then editing it would be difficult, whereas here, we simply need to edit in a file. So, this is generally a very simple way to create and manage containers when we have multiple containers. So, let us start creating our YAML file. To create the file, we can stop our server here if we want. And inside our test application, we are going to create a new file. Since we are going to run MongoDB containers in this, we are going to call it `mongo-db.yaml`. So, we will define all our `mongo-db` details. First, we will define the version. So, we will take the same version that we took in the example, which was 3.8. After that, we are going to create the different services. Giving a tab space, we will define each of our services. The first service is our `mongo`. We can give the same name that we gave to the container. Now, under `mongo`, first, we will define the `image`. For Mongo, we know our image will be `mongo`. After that, we are going to define the `ports`. For ports, we know we will bind 27017 to 27017 by writing a slash in this way. And we can also define the environment variables. Now, there are two ways to define environment variables. Let us copy this environment variable. One way is to write a hyphen in this way and define our environment variable in this way. The parallel way to this is to give a tab space here and define environment variables with the help of this colon. So, we can pick either option. We are going to go forward with the colon option. So, in this way, we can define our environment variables. Here, instead of username, the second environment variable is going to be `password`, which we are going to set as `qwerty`. So, these are all our specifications for the `mongo` container. Now, just as we created `mongo`, we can also create our `mongo-express` in the same file. So, for `mongo-express`, our image will be `mongo-express`. Our ports will be 8081, bound with 8081. And similarly, we will have some environment variables. For environment variables, let's come here and copy our environment variables. So, the first variable will be this. After that, similarly, we have `admin-password` and our `MONGODB_URL`. So, let's copy this as well and paste it here. Now, within this URL, we can remove the strings and add a slash at the end if we want. So, in this way, our entire YAML file is complete. Now, this YAML file basically contains instructions on which containers our Node.js application will create and use. Now, to actually create containers from this YAML file, we use Docker Compose. Docker Compose has two important commands: the `up` and the `down` commands. So, basically, we write `docker-compose -f`, which is the option for the file. We choose the YAML file name that we have given, and these are our `up` and `down` actions. Saying `up` means that we want to create the containers defined in this file and start them in detached mode. If at any time we need to delete, remove the containers defined in this file permanently, then for that, we choose the `down` option. So, let us run this command in our terminal. We can also start our server: `node server.js`. And here, to run our Docker Compose command, we basically need to be in the directory. So, for that, we can `cd` to `Desktop` and finally `test-application`. Let us clear this. So, now, in this directory, we will understand which is about networks. When we ran the Docker command to create the containers, we explicitly defined which network we wanted to create them in. But if you notice in the YAML file, there is no network option. This is because in the YAML file, for all the containers we write, by default, our Docker Compose will first create a default network, and then run all the containers within that default network. So, the first thing is that whenever we define a YAML file, we don't need to create a Docker network there; it will automatically be done for us by Docker.

The composer is. The second thing that we need to understand is because we have already connected the Node.js application to a MongoDB server, we will first have to delete our already existing MongoDB containers to run these containers. Because our old Mongo Express container has been bound with the 8081 port, the new container can never be bound with the 8081 port. So, we can do this work from Docker Desktop. We have two containers that we created earlier. We are going to delete both of these containers and by going into images, we are going to delete both of these images. So now we have no images, no containers. We will set up our setup fresh with the help of Docker Compose. To run the command, we can simply write `docker-compose -f` and run our `mb.in` in detached mode. Let us enter this. So, first of all, we have the obvious warning that the attribute version is obsolete. It was not necessary to define it because the images of Mongo and Mongo Express were not available to us locally. So, both of these images are being pulled first. Their different layers are being downloaded. So, we see the output. First, a new network named `test-app-default` is created for us. After that, both of these containers are created. For that, we can simply access our Mongo Express on port 8081. Let us enter. So, we have the same user interface that opened. Now, one thing we will notice is that we had already created a database named `college-db`. It is not available here. That is because whenever Docker restarts or whenever we restart our container, we do not have any data persistence as such. Data persistence means that the old changes we made inside the database, the new collection we created, the new documents we created will not exist as soon as we stop our container. So, for data persistence, we use something called volumes in Docker, which we are going to study further. But for now, because we have created a new container, a fresh container, we will not find the old data here. So, we will have to recreate our database here, our `college-db`, and inside this database, we are going to create the same collection, `users`. Inside `users`, we will add the same new document. So, let's add it quickly. First, we can give our username, let's say `juno`, and after that, we can create the email `juno@gmail.com`, and similarly, we will create our password. Let us call this `password`, and we will save this. So, we have stored this information. Now, if we send a request to get users, our new information will be printed. So, in this way, we have verified that our Docker Compose has successfully set up our MongoDB containers with the help of this YAML file. So, this is how we use Docker Compose. Now, whenever we need to delete all these containers together, the command for that is also very simple. We simply write `docker-compose -f`, whatever our file is, `mb.in`. They are removed. Along with them, the network that was created is also removed. So, now if we check inside Docker networks, this network will no longer be available to us. The old network is available, which is `mongo-network`. We can also delete the old network if we want. So, to delete any network, we simply do `docker network rm mongo-network`. So, our network will be deleted. We can also verify. So, these are our default networks. So, this is how we use Docker Compose. Next, we are going to study one more common use case of Docker, which is Dockerizing our own application. Whether we have a Node.js application or it is a Python application, we can convert those applications into Docker images as well. So, basically, currently, if we have this `test-app`, which is basically a Node.js application, then what we are going to do is convert it into a Docker image, and then later, from this Docker image, we can create any one container or multiple containers. So, this process of converting our application into a running Docker container is called Dockerizing our application. So, once we have this Docker image created or Docker container created, then we can share it with our team members. And this is basically the entity that we can now deploy directly. So, we will convert our application into a Docker container. But generally, in a production real-life environment, practically what happens is there is a tool called Jenkins in the CI/CD pipeline, which does that work for us. So, basically, Jenkins will convert our entire application into a Docker image, and then this image can be published either to a public or a private repository for everybody else, either in a private organization or in a public space, to be able to access that particular image. So, the work of Dockerizing any of our applications is done by a special file, which is called a Dockerfile. So, basically, this Dockerfile is a blueprint of sorts, of how our Docker image and Docker containers should be built. So, the Dockerfile contains all the instructions on how we need to Dockerize our application. So, if we look at the syntax of what the Dockerfile looks like, we can visit this link. Otherwise, this is a demo of what the Dockerfile looks like. Inside the Dockerfile, we write different instructions like this, which are run one by one as our application is converted into a Docker image or a Docker container. So, there are many important instructions that are written one by one inside our Dockerfile. So, these are some of the most common instructions that are in the Dockerfile, among which we will cover the important instructions. The first instruction is our `FROM` instruction. Basically, generally, every Docker image that we want to create is based on a base image. Whenever we write `FROM`, after `FROM`, we have to define our base image. Now, what does base image mean? We can imagine the base image like this: currently, we have our Node.js application. To run this Node.js application, it is necessary to have Node setup already on our system. If Node.js setup is not there on the system, then we will never be able to run our app on our host machine. Similarly, when our application becomes a Docker image or a container, there are some specific dependencies inside that container that should already be set up. So, for a Node.js application, the base image is the Node image. So, first of all, to build our container or for our image, we need to have this Node image. And on top of this, we will be able to create the image of our test application. So, in this way, different layers of images are formed inside our Docker image. We have talked about this layering before, but now we will practically create these layers. So, whatever base image we want, we define it with the `FROM` instruction. Along with it, we also have the `WORKDIR` instruction. `WORKDIR` defines the working directory. This is the path in the image where files will be copied. And all the subsequent instructions will be executed relative to this directory. So, to copy files, we will use the `COPY` command. So, first, we define the path of our host, then we define the path of our image. For example, if we want to copy all these files and folders of `test-app` inside our image, which we will have to copy, only then will all this code be available to us inside the containers. So, for that, we will use the `COPY` command. Along with it, we also have the `RUN` command. The `RUN` command is used to run instructions inside our Docker image or container. So, whatever command we want to execute, we execute it with the help of the `RUN` command. For example, as given here, `RUN npm install`. So, this entire command will be executed first. After that, the subsequent files will be copied or the folder will be copied, and then all other work will be done. So, whenever we define our Dockerfile, there can be multiple `RUN` commands inside it because there can be many different commands that we want to execute. But just as we have a `RUN` command, similarly, we have a command called `CMD`. Our Dockerfile can have multiple `RUN` commands, but we only have one `CMD` command. We can imagine the `CMD` command like this: once the entire container is set up from our Docker image, then what is the one command that we want to execute to run that application? For example, the command that is our `CMD` command. This instruction sets the default command that a container using this image will run. For example, if we have successfully created a container for our Node.js application, then what command do we use to run this Node.js application? `node server.js`. So, this will be our `CMD` command inside our Docker container. So, we can have multiple `RUN` commands, but one `CMD` command. Along with it, we also have the `EXPOSE` instruction, with which we expose the port of any image. Along with that, we can define our environment variables with the help of `ENV`. So, these are some of the most common instructions that we define inside the Dockerfile. Using these instructions, we are going to create a Dockerfile for ourselves. So, to create the Dockerfile, we need to create our file inside the application itself. To create the file, we create a new file which we name `Dockerfile` with a capital D. So, we have to keep all the uppercase and lowercase letters the same. And in this way, we will create a file without any extension. We can also install Docker inside Visual Studio Code if we want, but that is not something that we want to do right now. So, we will start writing our commands inside the Dockerfile. So, first, we will define our base image, which is the Node image. If we want to understand this base image in a little more detail, then basically what we are doing is, basically, we want to create a Docker image, which for example, we are naming `test-app`. Now, to create the `test-app` image, there are some basic things that should already be set up inside our container, such as Node.js setup. So, for that, we are using this base image, which is called Node. Now, Node itself is a Docker image, on top of which another layer of our `test-app` is added. But Node itself can have its own base image. For example, if we go to Docker Hub and if we search for Node, so this is the official image for Node. Now, inside Node, there are multiple versions that are available. Let's take an example of this version, 23.7.19. The same instructions that we talked about are being used in our Dockerfile. Now, interestingly, there is a base image for the Node version, which is called Debian, and there is also a version available to us for Debian, which is `bookworm-slim`. So, in this way, this is based on Debian. So, in a way, it is using Debian. Our Node image is using Node. Our test application is using Node. And in the future, we can also build another Docker image on top of our application. So, this is what we mean when we were talking about layering or layers in a Docker image. So, in this way, when we are pulling any Docker image and multiple layers are being downloaded, then internally, in a way, we download their dependencies from each other in this way. Let's come back to the Dockerfile. So, we will create our image from Node. So, first, we are going to define the environment variables. Inside the environment variables, we are going to define the MongoDB username and the password. So, our MongoDB username will be, which we are setting as `admin`, and we will also have MongoDB password, which we are setting as `password`. Along with that, we will have a `RUN` command. With the `RUN` command, we will create a new directory inside our container, meaning inside the container that will be created from the image. We will create another new folder inside the root folder, which is `test-app`, and inside `test-app`, we will copy all our files and folders from the host machine. So, to copy, we will use the `COPY` command. Currently, in whichever folder we are, relative to the Dockerfile, in its parent folder, meaning inside `test-app`, we want to copy all the files and folders to this `test-app`. So, for that, we will go inside `/test-app` and copy all these things. And lastly, there is the `CMD` command. Now, in the `CMD` command, we want to write `node server.js`. So, we write all commands in the form of an array of strings. So, first, our Node command will come, followed by our `server.js`. Now, one additional modification we will have to make here. Basically, currently, because we were inside the `test-app` folder, we can directly run `node server.js`. But when our Docker container runs, we will be inside the root folder. `server.js` does not exist in the root folder. But where does it exist? It exists inside `/test-app`. So, instead of `server.js`, we will write the complete relative path here, which is `/test-app/server.js`. So, these changes we are making inside the command or folders are being made according to the Docker container that will be created later for our application. So, this is how we create our Dockerfile. So, in this way, we can create our file, save it. Now, to actually build a Docker image from this file, we need to run this command, which is `docker build -t test-app` and then we can define any tag we want. So, `-t` means tag, and then with a dot, we select our directory where our Dockerfile is available. So, to run this command, we can come here. We will run this command inside the `test-app` folder itself because our Dockerfile is available there. So, here we can write `docker build -t` our image name, let's suppose we want to name our image `test-app`, and for that, we can define any version, we can define `1.0`, we can define `1.1`, and then a dot. So, automatically, the Dockerfile will be detected by Docker and executed. So, this is how we have started building the Docker image, and in this way, our image has been successfully built. Now, to verify if our image was built or not, we can run `docker images` here. So, now, along with Mongo and Mongo Express, we have another new image, which is called `test-app:1.0`. We can also go and see it inside our desktop. So, this new image named `test-app` has been created for us. We can also see the size of this image. Now, to build a new container from our Docker image, we can simply write `docker run` our image name, which is `test-app`, the version, and we can run our container. So, `Server running on port 5050` will be printed for us. So, basically, we have created a new container, and successfully our application has started running inside it. So, we can also create and run a container in interactive mode. For that, we can do `docker run -it` our `test-app:1.0` with `bash`. As soon as we press enter, we are now inside the container. We are inside the root folder of the container, and this is the container ID. If we want, we can also do `ls`. When we do `ls`, we will see that the directory we created for ourselves, and the files and folders that were not necessary for Dockerizing our test application. Basically, this Dockerfile and YAML file were unnecessary for us. We did not need to create them as such. Along with that, we could have also skipped these `node_modules`. If we skipped `node_modules`, then inside our Dockerfile, we would have had to run another command, which would have been `RUN npm install`. Because if we did not have `node_modules`, then we would have had to install those `node_modules`, for which the presence of this command inside the Dockerfile would have been very important. So, whether we add `node_modules` or not depends on which additional commands we write inside the Dockerfile. So, let us exit from here. Now, practically, when we look at our Docker images, we have three images. These three images represent a single application. So, in a real-life scenario, what will happen is, to run all these three images, we will basically use Docker Compose. So, with the help of Docker Compose, we can integrate multiple images together. We can run all three of them, Mongo, Mongo Express, and our Node.js application, in three different containers and make them interact with each other. So, that is something that you can try on your own. Since we have now covered the Dockerfile, covered Docker Compose, we have seen the entire process of how we can manage multiple containers. Next, we are going to cover how to publish our Docker images onto Docker Hub. For that, we need to go and sign up on Docker Hub, which is available at hub.docker.com, and once we have signed up, then we can also visit our profile from here under the "My Profile" section. And here, we will see all of these options. Among these, we need to go to this "Repositories" option. So, as we create new repositories on Hub, we can push our code from the local system onto a public space. Similarly, our Docker images, which are...

Our local system's available resources can be made publicly available by pushing them into Docker repositories. To do this, we need to start by creating a new repository. This is our new repository, for which this is the namespace, and we need to give it a name. So, we'll name this repo "Test Application." After that, we can also write a short description about it. We can choose if we want to create a public or a private repo, and then we can finally move forward by creating this repository.

Once the repository is created, to push the Docker image we build on our local machine into this repository, we will create it with this exact name. So, let's copy this name. Here, we have already built our application. We have written all the commands in the Dockerfile. So, what we are going to do is simply build our image with this particular name. Docker has finally started to build our image. Once our image is built, let's clear this. It is now available in Docker Desktop.

After the image is built, we want to push this image from our local system onto Docker Hub. Before pushing, we need to log in to our terminal with the same account that we used to sign up on Docker Hub. Now, to log in in the terminal with the Docker account, there are two popular options. So, first of all, I am just going to do `docker logout`, which will remove my existing login credentials. And to log in, we can execute `docker login`. If you are someone who is using the username and password, we will enter the username, which for my account is "dev." Similarly, we will get a prompt to enter the password, we can enter the password, and we will be logged in normally.

The second way is that Docker provides us with this link, which we can open on our browser. In the browser, where we have already logged in with the Docker Hub account, and for that, we are already provided with this one-time device confirmation code. So, once, let's go and open this code. Here, this code that we have, we can paste it. We will continue and confirm. So, as soon as we confirm, we will be successfully able to log in. Here, as soon as we go, our authentication will be completed quickly, and finally, the login was successful. So, now we have logged into our Docker account.

Now, to push our image into the repository, we simply need to type `docker push` and then the image name. So, let's just copy this and push it. So, all of the different layers of the images are now being pushed onto the cloud. So, once the process is done, we can go here to Docker Hub, refresh, and we will be able to see the latest image. By default, because we did not specify any tag, the default tag for our image will be "latest." In fact, by going into tags, we can analyze the size, and along with that, we will also see this pull command.

Just as we have been pulling other people's Docker images until now, in the same way, we can now pull our Docker image. In fact, the application code that we have right now in Visual Studio Code, we can go and delete it if we want, because from now on, whenever we need the same application on our system, we can just pull the Docker image and run its container, and within the container, we will be able to use our application, we will be able to run it. So, in this way, any image that we create with the help of Docker, we can push it in the form of a public or a private repo onto Docker Hub. And now, if you are working in an organization or if you are working on a group project, then whatever project we need to build within that, we can push it, and now with all our team members, we can go and share that project. In fact, when we talk about open-source contributions, there also, the code of many organizations is available to us in the form of similar Docker images, which can now be pulled. So, in this way, we execute `docker push`.

The next concept that we are going to study is the concept of Docker Volumes, and it is a very interesting concept. So, in our previous example, we actually built a Node.js application that we Dockerized, with which we used MongoDB containers. In that application, we noticed that whatever our MongoDB database was, all the data we added, the database we created, the documents we created, the collections we created, none of those things were permanent. That is, if this is our host machine, and inside it, if this was the container that we created, let's consider this our MongoDB container for example, and this is the host. So, all the documents we were adding inside the MongoDB container, all the data we were adding, as soon as we stopped this MongoDB container and restarted it, all our old data was lost. So, by default, the virtual file system inside containers, in which all data is stored, if the container is stopped, all that data is lost. And when the container restarts, everything restarts from the beginning, meaning it starts fresh from scratch. But if we ever want to persist this data, then for that, we use something called Volumes.

Volumes in Docker are persistent data sources for containers. And the concept of a volume works as follows: basically, what we do is we can reserve an extra space on our host system, which is either directly managed by the host operating system for us, or in most cases, this space is managed by Docker. That is, the space that needs to be created and managed for this new volume is managed by Docker in most cases. And what we do is we mount this space onto our container, which means that in a way, we have established a connection of the container with this space, after which whatever data we store in the container is also replicated in this volume. So, tomorrow, if we stop this MongoDB container and want to restart it, the data will be fetched from this volume, and when the container restarts, it will be able to access the old data. In fact, even if we delete this entire container, we still have access to the data stored in the volume. So, that is the beautiful concept of Docker Volumes, with the help of which we can practically implement data persistence while using Docker containers.

Now, there is one more special thing about Docker Volumes, which is basically that tomorrow, if we need to run multiple containers as well, let's suppose this is our first container, Mongo 1, this is our second container, Mongo 2, and if we want, we can map both of these containers with the same volume. So, in a way, we can attach the same single volume with both or multiple containers. So, this is the fundamental overview of what Docker Volumes are and what exactly do they do. After this, we are going to see a small practical example of how Docker Volumes practically work. For that, we are going to run a small Ubuntu container. So, we can simply type `docker run` and we will run it in interactive mode because we want to see what kind of things, what kind of data is being stored inside our container.

Now, when we are running `docker run ubuntu`, along with that, we also need to pass an additional option, which is basically the option for volume. Now, whenever we need to define a volume, we can use a simple flag for a simple example, which is `-v`. With `-v`, we are defining which volume, which directory of our container. We want to run a container from this directory. And inside this container, we will run Ubuntu. Now, inside Ubuntu, we want to store some data. Let's suppose this is the data that we want to store, and this data is in the `/data` directory, which is basically our volume in the host system. So, to store it, we can create a folder on our desktop, `/desktop/data`. So, we want the mapping between the host machine and the container to be something like this: whatever data is stored here inside the container is getting replicated in this folder on our host system, local machine.

So, to create this entire setup, meaning to create this volume, to create this volume and mount it with this container, what do we do? First, we define the path of our host, meaning the host directory where the volume will be mounted. So, here, with `-v`, first of all, we will define the absolute path of the host, meaning our machine, `/user/`, then `abc`, then inside `desktop`, then inside that, the `data` folder. We will define this entire path. And we write the absolute path, followed by a colon, and then we will define the path of our container, which is `/test/data`. And as soon as we give this flag, a specific volume gets attached to our running container, and this entire system is set up for us. So, to do that, we have written the `-v` flag. Now we will define our absolute path, which is `/users/`, then the system name, then `desktop`, and inside `desktop`, we are going to create a new `data` folder. With this, we are going to attach `/test/data`, and this is how we are going to run the Ubuntu container.

So, with a running container, we are attaching our volume here. Let's enter it. Now, because the Ubuntu image is not available locally, first of all, that image will be pulled. And finally, our container is started. We can also see it in Docker Desktop. We have the image, and along with that, we also have the container. We are in the root directory. Our `data` folder is completely empty. Along with that, we can also open the same `data` folder on our desktop. So, on the desktop, this is the `data` folder, and this `data` folder is currently empty. So, let's minimize this. And here, inside this `data` folder, we are going to create a new file. Let's call it `index.html`, and along with that, let's create another file, `server.js`.

So, now, if we look inside our `data` folder within the container, we have two files available. And if we look inside the `data` folder on our desktop, meaning on the host machine, those same two files are available here as well, even though we did not create any files here. So, from this, we can tell that this setup of ours has been successfully created. Whatever data we are storing here is the same data that is available here.

After this, let's try to do one thing. What we will do is stop this container and restart it. Generally, if a container is stopped and restarted, any changes we have made in the virtual file system are deleted. But in this case, that will not happen because we have attached a volume. So, here, let's exit it and clear it. Currently, we do not have any running containers. So, let's start the Docker. Let's start this container. Let's copy the ID. And our container has started. Along with that, let's open this container in interactive mode with `bin/bash`. So, now we are inside the container again. We can `cd /test/data` and do `ls`, and we will have both of those files available. In a normal scenario, without volumes, this would not have been possible. And both of these files are available on our desktop. Along with that, even if we completely delete this container, meaning if this container is completely deleted in our entire setup, the folder is deleted, then the connection is removed, but still, this data will remain persistent inside our host machine.

So, to do that, let's clear this and stop the Docker. And let's also remove this container now. So, let's clear it. Now, we do not have any containers available in the containers. And if we go to the desktop `data` folder, that data is still persistent, even though we have deleted the entire container. So, in this way, our concept of volumes works within Docker.

Next, we are going to look at the usage of Docker Volumes when we are trying to work with Docker Compose. So, with Docker Compose, we will take the example of our same Node.js application. For now, in our Node.js application, we saw that as soon as we stop our container and start it, or delete the container, there is no such persistence in our MongoDB database. There, we will try to bring persistence with the help of Docker Volumes with the help of this YAML file. So, whenever we need to define a volume in Docker Compose, for that, we write `volumes`. And here, with a hyphen, we write our host directory. Let's bring the host directory path. For that, on the desktop, we have already created this folder named `data`. If we want to copy its path, we can simply type `/`, then the system name, then `desktop`, and `data`. We are just going to copy this and paste it here. And with a colon, when we are trying to mount a volume for the MongoDB container, for that, in our MongoDB documentation, `/data/db` is the directory that we are going to follow for the database. So, here we will write `/data/db`. And let's save this.

So, there is a single change that we need to define in our Docker Compose file to mount the volume. Now, when we come to the terminal, although Docker Desktop currently has only the Ubuntu image, we do not have any running containers as such. If we want to run our containers from Docker Compose, then we can simply type `docker compose -f` followed by our file name, which is `docker-compose.yml`. So, first of all, the images for both of them are being pulled, so MongoDB and Mongo Express, both images are being pulled. And finally, both of our containers are in the running state. So, here we can see that the Mongo Express server is now running at `localhost:8081`. If we go to Docker Desktop, we can also see our two new images. And in terms of containers, both of our containers for the test app are now running. So, we can go and visit `localhost:8081`. As soon as we enter, we will come to our Mongo Express UI.

Now, by coming here, we are going to do something interesting. We have attached the data of this database to this `data` folder on our desktop to make it persistent. So, we can see here that some files and folders have been automatically created, which means that our volume has been mounted with our container. So, here we are going to create "My College DB," a new database. And inside this, we will create a collection named "users." Inside users, we can add a new document. So, inside the document, let's define our email, for example, `@yahoo.in`. After that, we will define a username, so "jando." And after that, if we define the password, then here we can set any password. So, we have added a document to our collection.

Now, what we are going to do is, let's minimize this. We will stop all our running containers. We have stopped our containers. But still, our containers are available in our Docker system. Containers are available, images are also available. So, next, what we are going to do is delete these containers permanently. So, to delete, instead of our simple `up` command, we need to do `down`. So, all of our containers have been removed. Our default network has also been removed. So, here, there are no containers existing in our containers. Which, in the previous use case, would have meant that the data we created, as soon as we refresh, all the data should disappear. So, here we have refreshed. Now, containers are not running, so in a way, the database has completely disappeared. And this time, when we create fresh new containers again, because those containers will already be attached to this volume because of Docker Compose, because of that, when we start our new container, we will see our old data in the MongoDB database as well.

To verify that, let's re-run this command. Our new container setup has been completed. New containers have started. Again, we will go here and enter. So, this time, in Mongo Express, our old database, "My College DB," exists. Inside it, we already have the "users" collection, and inside the "users" collection, our old document also exists. The same data exists. And this persistence is achieved using Docker Compose.

Now, there are many other interesting things related to Docker Volumes that can be learned, among which the first is that we can create our own custom volumes. So, whenever we want to see all our volumes, for that, we can run this command, which is `docker volume ls`. So, all of our volumes will be printed. In fact, we can also see all these volumes on Docker Desktop in this "Volumes" tab. So, here we can look at all the volumes, we can see their size, and we can also see their details. We can also create our own custom volumes using this `create` command. And these volumes are basically called named volumes. Named volumes mean that as soon as we create a new volume, Docker will automatically reserve some space on our host machine for this volume, and the name of that directory, that place, which can now be mounted with the container, will be what we define here. So, let's create a new volume. We will call it `docker volume create my-volume`. And...

In this way, we will get this volume. If we want, now we can execute `docker volume ls`. So now we will have our volume. We can also look at this volume in Docker Desktop. Here, a quite important question that should hit us is, earlier when we created `documents_fragment`, this volume that is being created with the name `my_volume`, where exactly is it being created? By default, Docker on Windows creates our new volumes at this location. And on Mac, it will not be available. So, in this way, we deal with volumes. Now, all these volumes that we have created so far are all named volumes that are not yet attached to any running container. Meaning, the volumes that we create with the `create` command are isolated right now and not attached with any running container. But the use of volumes, the meaning of volumes, is only when they are attached with a running container, because their job is to persist the data of that container. So, to attach a volume with running containers, we majorly have primarily three ways. And there are two important flags that we use for this task. One is our `--volume` flag, with which we can attach a volume with a running container. And one is the `--mount` flag. Both of them have almost the same job. Their result is also almost the same. First, let's see an example of how we can use the `--volume` flag. We can simply write the short form of `volume`, which is `-v`, a practical example of which we have already seen. So, to mount any of our volumes with a container using the `--volume` flag, we have three different ways. The first way is that whenever we are running Docker for any container, there, by writing `-v`, we first write the name of our volume. So, any volume that we have created, this volume name can either be an already created volume, or it can be a new volume that we are creating. And after that, we write the mount path. The mount path is basically the path inside the container where this volume will be mounted or attached. This type of volumes that we have are called named volumes because they have a specific name by which they can be referred. So, named volumes are one of the most popular ways to create and manage volumes inside Docker. And generally, when we talk about production environments, we use named volumes the most there. This is the most preferred way to deal with volumes. The second way to mount volumes is with the help of anonymous volumes. Basically, we simply write `docker run -v` and after that, we only give our mount path. This mount path is basically the container directory where the volume will be mounted. So, if we want to create a temporary storage, then we prefer anonymous volumes there. And the third type for creating volumes, of which we already have an example, these are called bind mounts. In bind mounts, we specify our local host directory, and then we specify the mount path. So, this is also one of the ways of creating volumes. Now, generally, these two methods and the bind mount process have a subtle difference. And that is, when we are talking about bind mounts, the Docker daemon on the host machine, the operating system of the machine, manages it. Whereas in the case of named volumes and anonymous volumes, Docker itself creates our volumes, and Docker itself explicitly manages those volumes. So, this is a subtle difference, but we can do any of the three if we want, depending on which type we are choosing. We have different different use cases. The work that we can do with volumes, the same work we can also do with `--mount`. If we want to look at examples of how to use `--mount`, we can go here onto this link. And this is the official Docker documentation. If we look at the syntax, if we are running this command for a volume, in which we first write the volume name, then the mount path, this is basically an example of named volumes. To do this same work, we can also use the `--mount` flag, in which we will define the type as `volume`, in the `source` we will have to define the volume name, and in the `destination`, we will have to define the mount path. So, it's a straightforward method, it's a similar flag, and the same options that we can use in both flags. So, this is how we mount volumes when we are trying to create and run a container. Along with this, there is also one more popular command which is called `docker volume prune`. Whenever we have unused local volumes which are not being referenced by any container, then this command does the job of deleting or pruning all those volumes. Generally, by default, this command only targets anonymous volumes. So, if we have created many anonymous volumes, like let us take an example of this scenario when we have the host machine, inside which we have created two-three containers, and for these, there are some anonymous volumes that we have created. Now, when tomorrow, it's possible we have deleted these containers, we don't need them, then it's possible these anonymous volumes persist inside our host machine. So, the `docker volume prune` command does the job of deleting them for us, which automatically deletes these unused anonymous volumes by default. So, this is also an important command that we can use from time to time. Now, finally, we are going to cover some more concepts related to Docker networking. We have already covered Docker networks in our lecture before. So, when we create any container on our host machine, by default, this container has some kind of networking enabled with it. So, generally, whenever we talk about Docker network or Docker networking, we are talking about how any of our containers will form connections with other containers or with the host machine or with all the entities outside, or how they will interact. So, Docker networking is all about how the containers are going to interact with the outside world, how outgoing and incoming connections are going to be formed. Now, we have already covered many concepts related to networking, like for example, if we ever want to look at all of the networks, we can write `docker network ls`. So, we will get all the networks. By default, we already know Docker creates three networks for us, and different drivers are attached to these three networks. Drivers are basically the most important helpers that define how a system will send or receive messages over a network. So, there are three types of drivers that are the main ones: one is our bridge driver, one is the host driver, and one is the null driver. We will understand all three in detail. Along with that, we have also seen that whenever we want to create a new network, we can simply write `docker network create` and we can create a new network. Let's call it `my_network` and we can do `docker network ls`. So, by default, we can create our own networks in this way. And an interesting thing we will notice is that by default, any network we create has a bridge type driver. So, first of all, let's talk about this bridge driver. So, whenever we talk about drivers, bridge, host, and null types are most important. First of all, we are going to talk about our bridge driver. Basically, whenever we create a new container inside Docker, our containers are created something like this inside our host machine. And by default, all our containers get attached to the default bridge. So, whenever in our network, when there is a default bridge driver, all containers can interact with each other. Plus, they can also interact with the outside world and with the host machine with the help of this bridge driver. We can also read about this bridge driver in our documentation on this link. So, basically, in bridge, the default network driver is bridge. If you don't specify a driver, this is the type of network you are creating, which we have already seen in the example that when we did not specify a driver, then by default, bridge type came into our network. So, bridge networks are commonly used when your application runs in a container that needs to communicate with other containers on the same host. Here, if we create multiple containers, then by default, when we have multiple containers, and we want our Docker container to be able to interact with other containers on the same host machine, then we use our bridge network driver there. Now, whenever we are talking about bridge as the type, we have two types of networks that we create. One is our default bridge network, and the other is our custom bridge networks. We have already seen the default bridge network here, which comes pre-built. And this is our custom bridge network that we create. There is a subtle difference between both. Basically, we created the custom network in our Node.js application, in which we had two containers, which we created. And in that custom bridge network, the containers were able to interact with each other directly. And that is why the containers in custom networks can interact with each other without any additional port name or container ID, or any extra specification like that. They can connect directly and interact directly. And that is how Mongo and Mongo Express were able to interact with each other because we created a custom bridge network. So, in this way, we have bridge networks in Docker, with which we can use default and custom networks. The second common type of network that we have is the host network. In the host network, basically, the container that we have created uses the same network as our host machine, because of which our container does not have its own IP address. So, the container is created with the same network as the host machine. And the third type of network is the null network. The null network basically says that when we want to create a completely isolated container, a container that is isolated from other containers and also isolated from the host machine, if we want to create this container in such a network, then we use the null network. So, by default, Docker provides us with all three of these networks, and we can also use our custom bridge networks if we want. If we look at the practical use case types among these, in the majority of cases, we use our bridge network, and the second most common case can be our host network. So, this is all about networking in Docker. We have covered many things in today's lecture, starting from Docker images and Docker containers, to creating our own custom images, to using other Docker images while we are building our own Node.js application. And this is something that you can also replicate in other technologies. Also, if you are working with Python, you can use Docker images and containers, and you can also use Docker Compose to manage your applications. We have covered in detail how to containerize our application, how to publish it on Docker Hub as a public repository. Along with that, we have covered in detail important Docker concepts like port binding, like Docker networking, like Docker Compose, how all these things work. So, I hope that today's lecture taught us a lot of new and interesting things about using Docker with our development process. And I hope that all the learnings from today's lecture will be used by us on a day-to-day basis in our development process.
