I don’t really have anyone else to shout at about this, but it’s an amazing way to host services in rootless containers entirely in user space using systemd (systemctl --user
).

Using them here to run everything. My whole *arr stack is running in a Quadlet pod. Really convenient, especially the auto update and rollbacks.
I love the concept too and I just hope it will catch on much more than this. To convert your compose files you could use Podlet. I’m also working on converting it to JavaScript(PodletJS) so it’s available in it-tools.
Go for Podlet though, really nice for command lines.
Sorry for all the links, I got overly excited 😆
Agreed. Quadlets and podman are amazing.
I like them very much as well, only thing I’m annoyed about is that you always need to drag that
--user
option… I mean, if I’m not using root or sudo, shouldn’t it be clear that I’m talking about the user space?Agreed! That would be a huge QoL improvement (and work just like the podman command does). Now I’m thinking about other commands that force this silliness, like
pip
.I’ll probably just make an alias
hell yeah! i moved my whole setup from docker to podman with systemd with quadlets. auto updates and everything. so smooth.
Ah yes, a fellow quadlet enjoyer. Cheers!
Did
$ /usr/lib/systemd/system-generators/podman-system-generator --user --dryrun
Also prove to be really valuable, too?
I didn’t use that! I had a docker-compose file and used podlet to translate (which took a little massaging due to it not supporting interpolations).
/usr/libexec/podman/quadlet --user --dryrun
was quite helpful though!
If you want to use caddy as proxy for other containers running as quadlets have a look at this repo: https://github.com/eriksjolund/podman-caddy-socket-activation
It certainly demystified some network shenanigans for me.
Nice, did the same for some services I run at home. Now in the process of migrating my stuff on my vps from docker compose to quadlets. It’s a bit more involved but worth the QoL stuff quadlets bring with them, like automatic updates and systemd integration. I’m curious, which is your Linux distro of choice to run your podman quadlets on?
ucore (soon to be cayo) on my home server!
They are generally pretty good but troubleshooting them is a pain. Quadlets are also a bit more more complex than Docker compose.
Note: User space includes root and anything not running in kernel space.
I hate docker compose and find that much more complicated. It’s a whole other structure that’s essentially unneeded.
But I started with podman and not docker, so that’s probably why
Yeah, those are very convenient and much easier than having to deal with Kubernetes or such.
Yeah replacing my k3s -> microk8s -> k3s multi-month headache with like 5 basic quadlet files in an evening was so wonderful and a relief
