Docker For Windows | Setting Up Docker On Windows

7 / 11 Blog from Docker

If you’re looking for simple and painless software deployment, Docker is the right tool for you. It is the best containerization platform and in this blog on Docker for Windows we’ll specifically focus on how Docker works on Windows.

To get in-depth knowledge on Docker, you can enroll for live DevOps Certification Training by Edureka with 24/7 support and lifetime access.

I’ll be covering the following topics in this blog:

1. Why use Docker For Windows?
2. Docker for Windows prerequisites 
3. Components installed with Docker 
4. What is Docker?
5. Docker Terminologies
6. Hands-On

Why use Docker for Windows?

• Avoids the work on my machine but doesn’t work on production problem: This problem occurs due to the inconsistent environment throughout the software development workflow. With Docker you can run an application within a container which contains all the dependencies of the application and the container can be run throughout the software development cycle. This practice provides a consistent environment throughout the software development life cycle
• Improves productivity: By installing Docker on windows we’re running Docker natively. If you’ve been following Docker for a while, you know that Docker containers originally supported only Linux operating systems. But thanks to the recent release, Docker can now natively run on windows, which means that Linux support is not needed, instead the  Docker container will run on the windows kernel itself
• Supports native networking: Not only the Docker container, the entire Docker tool set is now compatible with windows. This includes the Docker CLI (client), Docker compose, data volumes and all the other building blocks for Dockerizied infrastructure are now compatible with windows. But how is this advantageous? Since all the Docker components are locally compatible with windows, they can now run with minimal computational overhead.

Docker For Windows Prerequisites

The following requirements need to be met before installing Docker on windows:

1. Check if you’re using Windows 10, either pro edition or enterprise edition, 64-bit system. Docker will not run on any other windows version. So if you’re running on an older windows version, you can install the Docker toolbox instead. 
2. Docker for windows requires a Type-1 hypervisor and in the case of windows, it’s called the Hyper-V. Hyper-V is basically a lightweight virtualization solution build on top of the hypervisor framework. So you don’t need a virtual box, you just have to enable the hypervisor.
3. And also you need to enable the virtualization in BIOS. Now when you install Docker for windows, by default of this is enabled. But in case you’re facing any issue during installation, please check if your Hyper-V and virtualization is enabled.
