Now try migrating all your docker containers to podman.
Don't encourage me.
And then try turning on SELinux!
I set my homelab up on Bazzite immutable with podman and SELinux. It took a while to work everything out and have it boot up into a valid state hahaha
Any reason you chose Bazzite for your homelab distro? First I've heard of someone doing that!
At the start I just wanted a desktop machine that runs Steam through sunshine/moonlight so hardware support and gaming stuff such was very important.
My homelab used to run on my laptop when it could all fit within a couple 100s of GB and I was the only user but moving it was tricky. Since I'm a programmer I'm not afraid of this stuff so I just spent the hours to figure out one problem at a time.
I ended up figuring out adding HDD whitelist in SELinux, make it accessible in podman, manually edit fstab because tools didn't work, systemd service for startup, logging in automatically where I already forgot everything and would have not had to do any of this on a bog standard Ubuntu server.
Respect! I too often take it for granted that it's a privilege for my gaming rig and my homelab server to be separate boxes.
I came to the same conclusion, Nobara for would have been best.
Wouldn't an immutable OS be overall a pretty good idea for a stable server?
Good for stability, bad for flexibility for when the homelab grows more complex.
It's not that difficult to get SELinux working with podman quadlets, especially if you run things rootless. I have a kerberized service account for each application I host and my quadlets are configured to run under those. I very rarely encounter applications that simoky can't be run rootless but I usually can find an adequate alternative. I think right now the only thing that runs as root is one of the talk or collabora containers in my nextcloud stack. No selinux issues either.
I use podman-compose with system accounts and I don't have a ton of issues. The biggest one is that I can't seem to get bluetooth and pip working on Home Assistant at the same time. Most of the servers I manage have SELinux and it works fine as long as I use
:z/:Zwith bind mounts.A few years ago, I set up a VPS for my friend's business; at the time, I didn't know how to work with SELinux so I just turned it off. I tried to flip it back on, and it somehow bricked the system. We had to restore from a backup. Since then, I've been afraid to enable it on my flagship homelab server.
are you sure it really bricked it? when turning it on, on next boot it needs to go over all the files and retag them or something like that, and it can take a significant amount of time
Honestly, I don't know what happened, but it was unreachable via SSH and the web console. There shouldn't have been a ton of files to tag since it was an Almalinux system that started with SELinux enabled, and all we added was a container app or two.
that does not matter, it needs to go over all of them. I don't know how long it takes with SSD, but with HDD it can take a half an hour or more, with a mostly base system. and the kernel starts doing this very early, when not even systemd or other processes are running, so no ssh, but web console should have been working to see what its doing
Just did that last weekend. Nothing to do anymore. 😢
Did you do Quadlets?
Yes of course. Had to spend a couple of hours fixing permission related issues.
But did you run them as rootful or the intended rootless way.
Rootless. The docker containers were rootful, hence the permission struggles.
I had problems getting apps with multiple containers working in quadlets (definitely a knowledge issue on my part, but didn't feel the time learning it was beneficial, but will probably revisit during kubernetes learning) so went back to podman with docker compose.
I think it's kinda better using quadlets, because I wrote some custom scripts, and quadlets made the process better. But podman compose is probably file too.
And then migrate all your podman containers to proxmox
