Pre-requisites: Windows OS, Docker
Before understanding the concept of Docker, let’s first discuss the concept of Hypervisors. So in an IT Company, or any cooperate, there is a development team, a testing team, and an operation team for developing the application, testing it, and deploying it. Now suppose the developers are working on a different OS, for example, let’s say macOS, and they used some dependencies or libraries as per the language they are using, so they just won’t hand the software to the testing team, but also the libraries, but now, the application didn’t run o the tester’s machine, but it worked on the developer’s machine, maybe because the tester’s machine has different OS features than the developer’s one, so now, devs have to send the OS, but that is not practically possible, as one can’t just copy the C drive and hand it over, that’s where the concept of Hypervisors comes into the picture, think of this as a virtual machine or Wim-ware, so you have the physical hardware, you host an OS on it, and the OS can now host another OS also called Guest OS, and this guest OS can be packed and send to the testing team.
But the problem here is, for every application, one needs a different OS, this will result in a waste of resources as multiple OSs will be running. So for this problem, we have the concept of Containers, the difference between Hypervisors and containers is that we don’t need multiple OS for every application, multiple applications can share the same OS kernel, great isn’t it? So instead of installing HYPERVISOR, we will be installing Docker.
What is Docker?
Docker is an open-source platform where we run our applications in the form of containers. Docker containers are very light in weight and contain all the dependencies and configurations so we can run them across different computing environments. Developers can package all the dependencies of the application in the form of images it can be portable easily or shared easily with other developers without worrying about the underlying OS.
- Windows 11 64-bit: Home or Pro version 21H2 or higher, or Enterprise or Education version 21H2.
- Windows 10 64-bit: Home or Pro version 21H2 or higher, or Enterprise or Education version 21H2.
- 4GB RAM or Higher.
- Hyper V feature must be enabled in Windows.
- RAM: The minimal amount of Memory needed to run containers smoothly is 4GB, however, if a program has more complicated functions, it will need more than 6 GB RAM.
- Storage: For running the containers and installation of docker the minimum space required is 25GB. If you want to store the container images and data then we need at least more than 35 GB to 40 GB.
- Network: To download, push and pull the images we need active internet then only we can maintain the container images with the help of docker.
- CPU: At least a 64-bit processor is required for docker.
Docker can be run on a laptop with 4 GB of Memory, a 64-bit processor, and 25 GB of storage. It might change based on our use cases.
Step-By-Step Docker Installation On Windows
