Docker for Windows

Docker has out-of-the-box support for Windows, but you need to have the following configuration in order to install Docker for Windows.

System Requirements

Windows OS	Windows 10 64 bit
Memory	2 GB RAM (recommended)

You can download Docker for Windows from − https://docs.docker.com/get-docker/

1. Double-click Docker Desktop Installer.exe to run the installer.

2. When prompted, ensure the Use WSL 2 instead of Hyper-V option on the Configuration page is selected or not depending on your choice of backend.

   If your system only supports one of the two options, you will not be able to select which backend to use.

Run Computer Management as an administrator and navigate to Local Users and Groups > Groups > docker-users. Right-click to add the user to the group. Sign out and sign back in for the changes to take effect.

Once done, you will see Docker configured and launched. You will get an interactive shell for Docker.

To test that Docker runs properly, we can use the Docker run command to download and run a simple HelloWorld Docker container.

sudo docker run hello-world

This command will download the hello-world image, if it is not already present, and run the hello-world as a container.

Output

When we run the above command, we will get the following result −
