Docker Changelog CLI plugin

Docker Changelog CLI plugin

Based on a tweet by @Tomwillfixit

Just a quick fun conversion to make it work as a Docker CLI plugin

To use it (assuming you're running a beta of Docker 19.03):

  1. create the plugins directory

    mkdir -p ~/.docker/cli-plugins
  2. download the "plugin", and save it as ~/.docker/cli-plugins/docker-changelog (note: no .sh extension!)

    curl https://gist.githubusercontent.com/thaJeztah/340fe943e5f0426407eec32e22809ec4/raw/d843dab795c34fb703e780eb221ebe7075e0d3be/docker-changelog-plugin.sh > ~/.docker/cli-plugins/docker-changelog 
  3. make it executable

    chmod +x ~/.docker/cli-plugins/docker-changelog
  4. run the help command to verify the plugin was installed

    docker help
    ...
