Well, after a while in the container world ive come to realise that keeping all these containers up to date is hard work and time consuming with simple docker compose. I’ve recently learnt that portainer may come to hand here. I believe that feeding the yaml file through portainer allows the latter to take control of updates. Correct?

I have a Truenas Scale machine with a VM running my containers as i find its the easiest approach for secure backps as i replicate the VM to another small sever just in case.

But i have several layers to maintain. I dont like the idea of apps on Truenas as I’m worried i dont have full control of app backup. Is there a simpler way to maintain my containers up to date?

    At work I use kubernetes and quite like that (upgrading containers without downtime FTE), but I didn’t bother trying to set up the infrastructure myself. Some argue, it’s not with the efford for self hosting, I dunno.

    What I do like to use is Dockge, to keep docker but also keep your sanity. It even offers a single button for “docker compose pull”, which is great of you don’t have to many compose files / stacks. Combine with a simple shell script to batch pull/build all stacks in one go, plus some backup solution, and it’s actually nice to use and does all that I need. I love CLIs, but I’ve had situations where the GUI came in very handy.

    #! /bin/bash
# note: this will update and START all dockge stacks, even if you stopped them before
shopt -s nullglob
for proj in /opt/dockge /opt/stacks/*/; do
  echo "> $proj"
  docker compose -f "$proj/compose.yaml" up --pull always --build --detach
  echo ""
done
