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?
Use Nix. It is MUCH more deterministic and capable than silly Docker. It can even be used to deterministically create docker images if you really need them.
Am I mistaken, but isn’t Nix a package manager, where Docker is a container system? They’re related, but really not comparable.
You’re badly misinformed.
Nix is a language, a package manager (the biggest in the world), a dev environment scaffolding, a systemd orchestration tool, a full Linux distribution, and pretty much anything that you can describe infrastructure-as-code as. You can literally do almost anything with Nix. You can even build entire OCI/Docker images with just one Nix file.
Wow it does all that? Definitely not what we need, then.
