 #
 # Resource script for running docker-compose
 #
 # Description:  Manages docker services using docker-compose as an OCF
 #               resource in an High Availability setup.
 #               It relies on a well-tested docker compose YAML file which
 #               distributed on an identical location on all cluster nodes.
 #
 # Caveat: 1. A YAML file (docker-compose.yml) and an optional Dockerfile
 #            must be provided in a working directory.
 #         2. It is suggested to test run the docker-compose and verify
 #            on all cluster nodes before enabling this agent.
