I've always wondered if I was using containers wrong because none of them I've ever had to create were complicated. Maybe it's because I choose tools that make local development easy (Go + sqlite + various CLTs) or maybe it's because I never hard to interact with this on the professional side outside of making images for our projects (which still weren't complicated for the reasons above).

LLMs make containers in a pretty workable format for me (still hand tweak the env variables for a sanity check).

How exactly does it struggle here and why does postgres need to be built? Were the needs beyond what you get in a base image?
