Used Portainer so far, but that's a bit bloated for my simple use (one host, no-HA, lab env). Kubernetes is way too complex as well.
Warewulf sounds fun to try :D all of my profiles would probably only have one node. Does Warewulf make a fraction of sense when having a tiny, quasi-local environment?
EDIT: ah, nevermind. stateless and temporary makes no sense for my usecase, as my containers will run 24/7 with rare changes. But I will think about Warewulf if I ever dive into large-scale containerization :)
