docker-compose.yml

###  Development docker-compose file
#   This docker-compose.yml file is useful for development and debugging as it mounts the project directory into
#   the running application containers.  While the 'app' container will restart as code changes, the 'task' container
#   will need to be manually restarted to pick up the changed application code.
