Docker on WSL

Docker is a utility which containerizes applications. To set up docker with the WSL, follow these steps:

1. Install Docker for Windows.
2. Check the WSL version of your Ubuntu distro. In the Ubuntu command line,

   wsl.exe -l -v
   

3. If the version of your Ubuntu distro is 1, you need to upgrade to WSL2. To do this, set the version in Windows Powershell.

   wsl --set-version Ubuntu 2
   

4. Follow the instructions on the Docker website to add your Ubuntu distro as a Docker resource.
5. Test the docker installation. In Ubuntu:

   docker run -d -p 80:80 docker/getting-started
   

   And verify the app by accessing the following URL:

   http://localhost
   

   You can also see the app running in the Docker GUI.
