It's called docker-compose, and it's really simple compared to even a 1 pod k8s. Or maybe I'm misunderstanding what you mean by bringing up a set of services.
Yeah seconding the recommendation for docker-compose, it's a great way to start up multiple services and once you know the syntax, pretty straightforward to use in my limited experience. You can essentially declaratively define which other Docker containers you want to start up (in which order), which volumes they can use, and which ports should be exposed.
