These samples provide a starting point for how to integrate different services using a Compose file and to manage their deployment with Docker Compose. Supports check mode. ": Start with your base Docker Compose file for your application (docker-compose.yml): On our development server, we want to expose some ports, mount our code as a volume, and build our web image (docker-compose.override.yml): docker-compose up automatically reads the override file and applies it. This starts sets of services using 3 separate databases (nginx and mongo used as example). But they can be overridden by the values you might have defined in each of your environments (host OS or environment variables from your cluster). By using Compose, we can define the services in a YAML file, as well as spin them up and tear them down with one single command.
