My understanding is that it is an experimental implementation currently.

All these things you described can be done with systemd units in regular RPMs. In fact, for the AAA solution, I *already* did that so that we can reuse it for the Fedora and openSUSE deployments[1]. While I think it'd be valuable to figure out the container workflow for apps deployed in containers, let's not forget all that stuff in our infrastructure requires OpenShift, and I don't know about most of you, but I'm fresh out of OpenShift at home to be able to do this sort of thing. I have made something really simple that kind of works for OKD 3.x[2], but no such equivalent exists for OKD 4.x, so that's been out of reach for me for a while. Plain Kubernetes literally does not work. Aside from plain Kubernetes being a pain to actually get working enough to run applications, we actually use OpenShift features that do not exist in Kubernetes. So I would caution all of this by stating that at least for me as an external no-name plain contributor, I'm more or less locked out of contributing to apps that are deployed exclusively through OpenShift.
