It's similar to my own setup. I just do it in kubernetes instead of docker. One thing you can consider is a CI that runs renovate on a schedule to PR you when it finds new container image versions.

Here's my setup so you can take some inspiration if you want.

This is me. Can't hurt to just do a reboot

Why not use the jacobalberty version?

Wait until you learn about docker and kubernetes. You will not touch virtual machines again (for the most part) 😂
