Coolify is usually loved by the community.
Dokploy is another good one.
Kubero seems nice for more kubernetes oriented tasks.
But I feel like if someone is having a single piece of hardware as the OP did. Kubernetes might not be of as much help and Coolify/Dokploy are so much simpler in that regards.
Thanks. I will look into those.
I suppose kubernetes with the right operators installed and the right node labels applied could almost work as a self service control plane. But then VMs have to run in kubevirt. There is crossplane but that needs another IaaS to do its thing.
