Docker is hard work - Lemmy

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?
