Ask HN: What's needed for a minimal production Docker deployment?

There's a lot of tutorials/books online about getting a basic server with docker running but seemingly few that cover everything that is needed for a true production deployment (or is simply nothing more needed?). I would be curious, if anyone can share a good resource for doing real single-server production Docker deployment on your own VPS. I.e. best practices for/how to:

- secure the server properly

- credential management

- making sure of security updates

- observability

- backups

- automatic deployments

- anything else that is needed

Many thanks for any pointers
