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 used a Single Node Openshift (SNO) instance to act as a RH ACM/ZTP hub, more information can be found here.
We used 6 KVM instances to simulate the baremetal servers, on top of those we installed OCP 4.12 and ran the upgrade through ZTP policies with TALM operator. More information can be found here.
We prepared two set of policies for OCP 4.12 and OCP 4.14. For a fresh-installed cluster those policies can be bound with cluster label 'config-version: 4.12' or 'config-version: 4.14'.
We also prepared a set of policies to handle the cluster/operator upgrade. Our target for the cluster upgraded from 4.12 to 4.14 is that the 4.14 policies shall be compliant on the cluster without special changes. The idea to drive the upgrade is to modify the cluster label with steps below:
- (initial state) config-version: 4.12
- (upgrade to 4.13) config-version: upgrade-to-4.13
- (upgrade to 4.14) config-version: upgrade-to-4.14
- (post upgrade) config-version: 4.14
We used ZTP/TALM to upgrade the cluster, following were the high level steps.
The cluster had been installed with ZTP, and it had been bound with policies with cluster label: config-version: 4.12; all policies are compliant:
