Installs Docker.

By default, it just installs the latest version of Docker. It follows these instructions.

After running this cookbook you can verify Docker is working by running:

$ sudo docker run hello-world

Chef's node has a top-level docker key so the configuration is done using the docker-config key.

"docker-config" => {
  "version" => string,
  "users" => list[string]
}

• version -- string, the Docker version to install, defaults to the latest version.
• users -- list[string], the users who will join the docker group. This should allow the users to run docker commands without sudo.

• Docker repo (supermarket)
