Used version ubuntu must be static, example 22.04 not latest. When release new version ubuntu behaviour can be change and functionality ci will be broken.

Image tags set latest, how users can find correct version? May be we can add calver in iso8601 format? Add git hash short and full commit hash? Semver? Mixed variations?

Thanks for the suggestions, I really appreciate it.
Keep in mind it's just a draft, it's not ready for review yet :)

Just took a GHA example and made some minor changes.

I think the real pipeline should be implemented after the discussion about versioning and all of this stuff.

@hiddenmarten pleaase make sure that pipeline works normally on other github repo.
You have to push changes to main, and try creating tag.

Eg. I tried to run it on https://github.com/kvaps/etcd-operator and https://github.com/kvaps/etcd-operator2 both didn't work

Now it works on my side:

https://github.com/hiddenmarten/etcd-operator/actions/runs/8221133878
https://github.com/hiddenmarten/etcd-operator/pkgs/container/etcd-operator

From my side LGTM.
