	// At this stage, you should have a neat redis cluster running. The Redis
	// client ports you previously set for each of your services are the `6379`
	// but you had to specify different available ports on your host machine.
	// You can hard code the different ports OR you can use the `Compose.Port`
	// function to find the correct port to use from a service name and the
	// combination of the port exposed and the protocol used such as `6379/tcp`.

	// whatever stuff you want.

	// In the end, you maybe want to clean the containers created. Just use the
	// `Compose.Stop` function just as you would use the `Compose.Start`
	// function. As no argument is provided, all services will be stopped.
