    # Getting the role list under SaltStack based on the instance name

    Idea is that once a VM is instantiated it knows what services he’ll handle.

    #
    # Idea is that if we send an event with a specific tag
    # we can trigger a code update (via Salt Reactor) on
    # the given project.
    #
    # The component that sends the event would be a script
    # that checks for git changes on remote git repository.
    #
    # If there are changes on that remote, that script first
    # the changes pulls them, and then sends the event.
    #
    # Reactor would then sync the code to their appropriate
    # destination.
    #
    # Event examples:
    #
    # salt-call event.send wpdn/changes/app/www
    #
    # Where:
    #
    # - `wpdn/changesi` would be namespace for code changes
    # - `app` would be the role to target (in roles grain)
    # - `www` would be the code repo that had been updated
