How to use LXC containers in Proxmox? (lemmy.ml)

Hello, have setup my proxmox server since some weeks recently I found that LXC containers could be useful as it really separate all my services in differents containers. Since then I figured out to move my docker's services from a vm into several LXC containers. I ran into some issues, the first one is that a lot of projects run smoother in docker and doesn't really have a "normal" way of being package... The second thing is related to the first one, since they are not really well implemented into the OS how can I make the updates?
So I wonder how people are deploying their stuffs on LXC proxmox's containers?
Thanks for your help!

EDIT : Tried to install docker upon debian LXC but the performances were absolutely terrible...

I tried docker directly on LXCs. Don't do it man. It's brittle, it barely works, and every proxmox update it will cause things to break. It takes forever to get working because you're disabling things that should not be disabled, and it will only get harder.

I spent years trying to make what you're talking about work well, and it never did.

Just install a VM and run docker in there. If you really want to make docker containers more generic, then really you may be ready to go full kubernetes.

I have the opposite experience of this. All of my local services are a single docker container inside an LXC. I don't like that it's conceptually messy, but in practice it's easy to manage. What I love about it is the simplicity of backing up or moving the entire LXC between servers.

I've not had any drama with things breaking across Proxmox updates. The only non-gui thing I need to do during the process is adding two lines to the LXC conf to have Tailscale work correctly.

Got performance issues. Tried with Debian and alpine nothing worked. Wouldn't recommend docker on lxc
