Ironically, their hard dependency on Docker is a showstopper for me - none of my systems run Docker Engine, they use containerd and Podman, neither of which are supported.

I hadn't heard of them, but I'm looking at their GitHub page now and they seem to support Kubernetes, which makes me think they must support containerd, right?

I run Authentik in podman; you could also in theory just run it without containers, although that would be obnoxious to set up.

Do you have a repo or example somewhere I can look at? Thanks
