error: resource mapping not found for name: "valkey-cluster" namespace: "mynamespace" from "valkey-cluster.yaml": no matches for kind "PodDisruptionBudget" in version "policy/v1beta1"

Hi,

On the K8S cluster I have installed valkey-operator:v0.0.11 in 'mynamespace'. The controller pod is up and running. Now I am trying to build a ValKey cluster using valkey-cluster.yaml with a little modification.
In this file I made a couple of changes

1. Updated the namespace from 'default' to 'mynamespace'.
2. External mages referred from docker.io to internal ones.

Step followed

$ k apply -f valkey-cluster.yaml -n mynamespace

Output:

networkpolicy.networking.k8s.io/valkey-cluster created
serviceaccount/valkey-cluster created
secret/valkey-cluster created
configmap/valkey-cluster-default created
configmap/valkey-cluster-scripts created
service/valkey-cluster-headless created
service/valkey-cluster created
statefulset.apps/valkey-cluster created
error: resource mapping not found for name: "valkey-cluster" namespace: "mynamespace" from "valkey-cluster.yaml": no matches for kind "PodDisruptionBudget" in version "policy/v1beta1"
ensure CRDs are installed first

Output of pods

❯ k get pods -n mynamespace | grep -i valkey

Output of describe

❯  k describe pod valkey-cluster-1

I wonder if

error: resource mapping not found for name: "valkey-cluster" namespace: "mynamespace" from "valkey-cluster.yaml": no matches for kind "PodDisruptionBudget" in version "policy/v1beta1"

is making the pods unschedulable?

PDB is a red herring, it looks like the STS PVC needs to adjusted

[dmolik]

the valkey-cluster.yaml is an expanded helm chart used as reference during development of the operator.
