This repo record the procedure and manifests used when upgrading a Multiple Node Openshift(MNO) cluster with Openshift Data Foundation(ODF) installed from EUS-4.12 to EUS-4.14.
We use a Single Node Openshift (SNO) instance to act as a RH ACM/ZTP hub, more information can be found here.
We use 6 KVM instances to simulate the baremetal servers, on top of those we install OCP 4.12 and run the upgrade through ZTP policies with TALM operator. More information can be found here.
We use ZTP/TALM to upgrade the cluster, following are the high level steps.
The cluster has been installed with ZTP, and it's been bound with policies with cluster label: config-version: 4.12; all policies are compliant:
