This is one of my pet peeves with containerized services, like why would I want to run three or four instances of mariadb? I get it, from the perspective of the packagers, who want a ‘just works’ solution to distribute, but if I’m trying to run simple services on a 4 GB RPi or a 2 GB VPS, then replicating dbs makes a difference. It took a while, but I did, eventually, get those dockers configured to use a single db backend, but I feel like that completely negated the ‘easy to set up and maintain’ rationale for containers.
