It varies a lot on what you're using. Postgres in particular is a bugbear because updating dockerized Postgres is hell at best and requires several backups in case you screw up. OTOH a bog standard python server backend can probably keep running for quite a while on alpine:latest without issue because it's not very reliant on much in terms of strange package availability (maybe old python versions that get deprecated every once in a while).
