I prefer setting up services that bind to port 0 ("get me an unprivileged port"), report that back, and use that to auto-configure dependent services.

This allows local development and debugging for fast iterations and quick feedback loop. But, it also allows for multiple branches of the same project to be tested locally at the same time!

Yeah, git does not make that seamless, so I'd have multiple shallow clones to allow me to review a branch without stopping work on my own branch(es).
