I have many services running on my server and about half of them use postgres. As long as I installed them manually I would always create a new database and reuse the same postgres instance for each service, which seems to me quite logical. The least amount of overhead, fast boot, etc.
But since I started to use docker, most of the docker-compose files come with their own instance of postgres. Until now I just let them do it and were running a couple of instances of postgres. But it’s kind of getting rediciolous how many postgres instances I run on one server.
Do you guys run several dockerized instances of postgres or do you rewrite the docker compose files to give access to your one central postgres instance? And are there usually any problems with that like version incompatibilities, etc.?
I care about the underlying tech in the things I deploy, but the reality is that I lack the time to actively do this in practice.
Ideally I would set everything up manually, but it’s just too hard to keep up with 30+ projects and remembering how/why I set everything up, even with documentation. Docker Compose makes my homelab hobby more manageable.
