I've never understood it either. I still deploy some things into their own respective manual deployments but for lots of things having a pre-made docker compose means I can throw it on my general app VM and it'll take 5 seconds to spin up and auto get HTTPS certs and DNS. Then I don't lose hours when I get two days into using something and realize it's not for me.

Also have you read some of the setup instructions for some of these things? I'd be churning out 1000 lines of ansible crap.

Either way since Proxmox 9.1 has added at least initial support for docker based containers the whole argument's out the window anyway.

Me neither. Docker is the platform agnostic way to deploy stuff and if I maintained software, it is ideal - i can ship my environment to your environment. Reproducing that yourself will take ages, or alternatively I also need to maintain a lot of complex scripts long-term that may break in weird ways.
