Yes? Well, every "app", as I quite explicity wrote. Look up the docker compose file or helm chart for basically any app. I'm running dozens of apps, each with their own postgres, redis and nginx containers alongside the main application server. That's what the stack is designed for.

The Compose file is written like that so you can quickly try the app without setting up extra dependencies. Usually not for production use.

Especially since in production you might want to scale the parts separately. I like to have a Postgres cluster to connect where backup is already handled, and the app then doesn’t have any persistent data, doesn’t need any network volume mounts.
