Description Scott Dodson 2019-04-15 13:17:02 UTC 
We need to seed a CI job that unblocks other teams from completing their tasks below.

We need to create CI job that is able to verify rollback of cluster state. The proposed flow is as follows

Installer - Provision 4.x cluster
MCO       - Edit machine config to write file to /etc/ whose content is “A”
Etcd      - Take etcd backup; capture static pod revision levels
???       - Update release payload
MCO       - Edit machine config to write file to /etc/ whose content is “B”
MCO         Wait for roll-out to complete
Master    - Shutdown kube-apiserver via manual manipulation of static pods on each master
Etcd      - Restore etcd backup
Master    - Restart kube-apiserver via manual manipulation of static pods on each master
MCO       - Wait for cluster to reconcile X period
Master    - All operators report old payload version
MCO       - Ensure on each worker /etc/ content is restored to “A” via MCO
