    Run Docker Compose as a Docker CLI plugin

Just a quick fun experiment to try to make docker-compose work as a Docker CLI plugin

docker/cli#1534 CLI Plugins Design
docker/cli#1564 Basic framework for writing and running CLI plugins

To use it (assuming you have docker compose installed):


download a and install nightly build of the docker cli (linux macOS)


create the plugins directory
mkdir -p ~/.docker/cli-plugins


download the "plugin", and save it as ~/.docker/cli-plugins/docker-compose (note: no .sh extension!)
curl https://gist.githubusercontent.com/thaJeztah/b7950186212a49e91a806689e66b317d/raw/36d4c5854523502deed5b56842b0d34cd6ec0f70/docker-compose-plugin.sh > ~/.docker/cli-plugins/docker-compose 


make it executable
chmod +x ~/.docker/cli-plugins/docker-compose


run the help command on the nightly docker cli to verify the plugin was installed
./docker help
...
Commands:
  build                     Build an image from a Dockerfile
  compose     (Docker)      Define and run multi-container applications
  login                     Log in to a Docker registry
  logout                    Log out from a Docker registry


enjoy!
./docker compose help
Define and run multi-container applications with Docker.

Usage:
  docker-compose [-f <arg>...] [options] [COMMAND] [ARGS...]
  docker-compose -h|--help

Options:
  -f, --file FILE             Specify an alternate compose file
                              (default: docker-compose.yml)
  -p, --project-name NAME     Specify an alternate project name
