Setup Docker

Setting up Docker for Windows

  • Download and install Docker CE from the official website 🗗.
  • Open settings and;
    • Share any drives that will be used to mount from.
    • Expose the daemon without TLS (if you understand the risks).
      • Exposing the daemon without TLS is an easy way to open it up for bash in WSL.
    • Turn off experimental features until you need them
      • Experimental features produced problems with containers filesystems for me before.

Setting up Docker for Bash in Linux Subsystem for Windows

Remove any old versions

Prevent troubleshooting as per MS WSL #2288 🗗:

$ sudo rm /var/lib/dpkg/info/docker.prerm
$ sudo rm /var/lib/dpkg/info/docker.io.prerm
$ sudo rm /var/lib/dpkg/info/docker-ce.prerm

It's fine if it says the file or directory doesn't exist.

Now remove any existing packages:

$ sudo apt-get remove docker-compose docker-ce docker docker-engine docker.io

Install Docker

Install packages to allow apt to use a repository over HTTPS

$ sudo apt-get install apt-transport-https ca-certificates curl software-properties-common

Add Docker's official GPG key

$ curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo apt-key add -

Set up the repository

$ sudo add-apt-repository "deb [arch=amd64] https://download.docker.com/linux/ubuntu $(lsb_release -cs) stable"

Update source lists

$ sudo apt-get update

Install Docker

$ sudo apt-get install docker-ce

Or otherwise official documentation 🗗 or this blogpost from Tomas Lycken 🗗.

Connecting Docker to Docker Daemon on Windows

Check if host OS Docker daemon can be reached:

$ docker -H tcp://0.0.0.0:2375 images

If so, set it as an environment variable:

$ export DOCKER_HOST=tcp://0.0.0.0:2375

Check if it worked:

$ docker images

If so, add it to our bashrc, to persist the change

$ echo "export DOCKER_HOST='tcp://0.0.0.0:2375'" >> ~/.bashrc

In case this method does not work anymore, have a look at this blogpost from Tomas Lycken 🗗 and check for any updates.

Install Compose (Docker Composer)

See below or read the Compose official documentation 🗗.

Windows

Docker CE for Windows already includes Compose.
