Definitely a lot of one-shot scripts for a given environment... I've started using a run/ directory for shell scripts that will do things like spin up a set of containers defined in a compose file.. build and test certain sub-projects, initialize a database, etc.

For the most part, many of them work the first time and just continue to do so to aid a project. I've done similar in terms of scaffolding a test/demo environment around a component that I'm directly focused on... sometimes similar for documentation site(s) for gh pages, etc.

Soem things have gone surprisingly well.
