Selfhosted
A place to share alternatives to popular online services that can be self-hosted without giving up privacy or locking you into a service you don't control.
Rules:
-
Be civil: we're here to support and learn from one another. Insults won't be tolerated. Flame wars are frowned upon.
-
No spam posting.
-
Posts have to be centered around self-hosting. There are other communities for discussing hardware or home computing. If it's not obvious why your post topic revolves around selfhosting, please include details to make it clear.
-
Don't duplicate the full text of your blog or github here. Just post the link for folks to click.
-
Submission headline should match the article title (don’t cherry-pick information from the title to fit your agenda).
-
No trolling.

I started with rootless podman when I set up All My Things, and I have never had an issue with either maintaining or running it. Most Docker instructions are transposable, except that podman doesn't assume everything lives as dockerhub and you always have to specify the host. I've run into a couple of edge cases where arguments are not 1:1 and I've had to dig to figure out what the argument is on podman. I don't know if I'm actually more secure, but I feel more secure, and I really like not having the docker service running as root in the background. All in all, I think my experience with rootless podman has been better than my experience with docker, but at this point, I've had far more experience with podman.
Podman-compose gives me indigestion, but docker-compose didn't exist or wasn't yet common back when I used docker; and by the time I was setting up a homelab, I'd already settled on podman. So I just don't use it most of the time, and wire things up by hand when necessary. Again, I don't know whether that's just me, or if podman-compose is more flaky than docker-compose. Podman-compose is certainly much younger and less battle-tested. So is podman but, as I said, I've been happy with it.
I really like running containers as separate users without that daemon - I can't even remember what about the daemon was causing me grief; I think it may have been the fact that it was always running and consuming resources, even when I wasn't running a container, which isn't a consideration for a homelab. However, I'd rather deeply know one tool than kind of know two that do the same thing, and since I run containers in several different situations, using podman everywhere allows me to exploit the intimacy I wouldn't have if I were using docker in some places and podman in others.

I make extensive use of compose in my own server so I'm assuming I'll need to transition to systemd confs. Do you run those or do you run everything by podman CLI?
Yeah, I use systemd for the self-host stuff, but you should be able to use docker-compose files with podman-compose with no, or only minor, changes. Theoretically. If you're comfortable with compose, you may have more luck. I didn't have a lot of experience with docker-compose, and so when there's hiccups I tend to just give up and do it manually, because it works just fine that way, too, and it's easier (for me).
