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.

Podman is quickly becoming shit as Red Hat continues to remove features and recommend you use Kubernetes. I ended up removing it from my servers and switching to Debian from Fedora because I don’t like Red Hat mucking about with our open source community software.
I still run Docker.
As someone who's been wanting to test (and maybe move to Podman) in the future but hasn't really spent any time on it, what features have Red hat removed from Podman?
My major beef is we used to be able to run a Podman generate command to make a user systemd file and auto start and stop containers with that. Even entire clusters of pods with one easy command and then just use the system level start and stop. They removed it in favor of “quadlet”which works fine for single containers, but for a compose, they literally just use Kubernetes syntax and the official documentation says just use Kubernetes. Well, what the fuck is Podman for then?
The biggest problem everyone ever has with Podman is it’s frustratingly obedient to SELinux. Docker just kind of makes its own permissions and opens its own ports and steamrolls past whatever security you have. Podman will refuse to read or write a directory for stupid reasons until you’ve gone round and round with SELinux, and then just when you have it working, when the container updates it locks the directory all over again(in my case, updating a Minecraft server to latest version would crash the server and lock the data directory). Red Hat continues to insist SELinux is cool and this is working as intended. Again, Docker just doesn’t give a shit and barges into the directory without a problem.
Every complaint here is PEBKAC.
It's a legit argument that Docker has a stable architecture while podman is still evolving, but that's how software do. I haven't seen anything that isn't backward compatible, or very strongly deprecated with notice.
Complaining about selinux in 2024? Setenforce 0, audit2allow, and get on with it.
Docker doing that while selinux is enforcing is an actual bad thing that you don't want.
