PodDisruptionBudget in version "policy/v1beta1"

MongoDB Percona Operator for MongoDB
1

Hello

Cluster is on 1.27.13-gke.1000000

Operator on 1.11

I mistakenly updated the cluster with an Operator version 1.0.9. I reverted back to Operator 1.11 but the logs on Operator do not look good and started up but:

kubectl -n dev-staging-mongodb01 get all

=> the RS does not startup ?!

Operator shows these errors non stop:

Hey @jamoser ,

I’m confused with versions.

  1. What was the starting version?
  2. Which version you upgraded to?
  3. To which you rolled back?
    3.1 And what was the procedure you used to roll it back?

PodDisruptionBudget v1beta is removed in k8s 1.25. Because of that we switched from v1beta to v1 API in Operator 1.13. Here is the PR: K8SPSMDB-760 pdb is policy/v1 since v1.21.0 by pkeuter · Pull Request #1017 · percona/percona-server-mongodb-operator · GitHub

So operator versions < 1.13 will throw the error about PDB on k8s >= 1.25.

Pls ignore. We have updated to the latest Operator and all is ok.
