= Deprecated `podDisruptionBudget` in the legacy {project_operator}
With this release, we have deprecated `podDisruptionBudget` field in the Keycloak CR of the https://github.com/keycloak/keycloak-operator[legacy {project_operator}].
This optional field will be ignored when the Operator is deployed on Kubernetes version 1.25 and higher.
As a workaround, you can manually create the Pod Disruption Budget in your cluster, for example:
```yaml
apiVersion: policy/v1
kind: PodDisruptionBudget
metadata:
labels:
app: keycloak
name: keycloak
spec:
maxUnavailable: 1
selector:
matchLabels:
component: keycloak
```
