Presenting a line of thought were OKD the parallel opensource project of Openshift could be a valuble multicloud Kubernetes distribution coupled with the open soruce Red Hat Advanced cluster manager. it is not yet fully open sourced yet, however it is just a matter of time. for now the hub needs to be openshift and spokes can be any kubernted including OKD

Cluster “A” has 2 running pods:
- name: A-000, version 3.3.0
- name: A-001, version 3.4.9-1
Differences from desired state (config)
- name: A-000, version 3.4.9-1
- should be 3 members (3 pods)
How to get desired state (config)
- recover one member
- backup cluster
- upgrade to 3.4.9-1
