Running docker on WSL (Windows Subsystem for Linux)

My build toolchain is frequently in there for node based applications, and I was looking for a way to run docker commands from WSL (Windows Subsystem for Linux https://docs.microsoft.com/en-au/windows/wsl/install-win10 ).

Note: The below steps are a quick way to get it working but involves disabling TLS authentication. A more involved way to do this without disabling TLS can be found at https://blogs.technet.microsoft.com/virtualization/2017/12/08/wsl-interoperability-with-docker/

 

This setup puts the docker engine in Windows on top of Hyper-V, but allows you to control it either from Windows, or within WSL by connecting it to the Windows Docker Engine.

  1. Install docker for windows https://docs.docker.com/docker-for-windows/install/
  2. Go into the Docker for Windows settings and expose daemon on localhost
    docker windows settings
  3. Install docker in WSL (it’ll just install the client) https://docs.docker.com/install/linux/docker-ce/ubuntu/
  4. Tell WSL to look for a docker engine on localhost
    TIP: put the export into your ~/.bashrc so you don’t need to run it ever time.
    export DOCKER_HOST=tcp://127.0.0.1:2375

Now you will be able to run standard docker commands run new images, show the running containers, etc. docker linux
