Ohh, looks extremely promising, I've been after something with a bit more flexibility than Dex while not being Keycloak/Java etc, an LDAP backend would be awesome as well though (another thing thats lacking is a simple ldap server, perhaps with sql as db, openldap is excessive and glauth isn't there)
I think I did and when I couldn't find useful installation details I gave up, I don't use docker or kubernetes, so if projects can't be bothered to make information available for a generic install, I immediately lose interest.
I do plenty of native installs, and I find Docker based instructions to be a pretty nice universal codex for how things work.
Docker entryscripts sometimes have significant magic baked in (alas), but quite often Docker is a distribution mechanism more than anything else. The Docker guides are - 9 times out of 10 - more than informative enough to show how to DIY in any other of the dozens if not hundreds of other system types you might have.
If you want to resist using the easy thing, I personally think it behooves you to not bounce so quick. You don't have to use it, and it's good nearly universal documentation as to how to operate the thing.
It means I have to sit and read through the Dockerfile (or compose, in many cases, which is even worse) and figure out what its doing and what magic variables I need to provide etc, when just providing a binary download url and an example (or reference) config does just fine, not everyone uses docker
Easy != Simple. Not everyone wants to play around with Dockerfiles, docker compose and what not. Sometimes a plain binary is preferred. I say this as someone who likes docker for certain use cases but docker is not my solution for everything.
Rootless Podman uses slirp4netns by default. The default will soon change to pasta. Pasta has better performance than slirp4netns. For best performance if your container supports it, use systemd socket activation because the traffic over the activated socket will have native network performance.
Probably for user containers, but I've only ran it as root generally to avoid those sorts of limitations so haven't noticed any issues - I rarely use docker and only use for quick testing and then switch to non-docker installs
