Having an environment like proxmox is very handy for learning and testing. When you find something to test, spin up a clean machine and you have a safe environment to learn that can be removed after. You can also try out different distros that way.

I’d recommend setting up Incus instead however, it works fine on a desktop/laptop if you’re running a linux distro they support and don’t have a dedicated machine to use.

They also have a very good tutorial/demo that shows the basics: https://linuxcontainers.org/incus/try-it/

Frogger, played a lot of that and had to stop myself before crossing roads for awhile after.

In my mind I was trying to optimize moving the same direction as the car and sneak in before the meeting car got there. I’m lucky to be alive.

From personal experience, if you’re hosting Gitlab and make it available to the internet, make sure to keep it updated or your server will be super slow hosting a crypto miner within a year.
