Jenkins pod priority cannot be set with priorityClassName parameter

[SohamChakraborty]

Pod priority is not changing

Hi,

We are trying to give Jenkins pods a higher priority than 0.

For that we tried to set priorityClassName to an already existing priorityclass. After then we tried to upgrade the release with helm upgrade. But the change doesn't get reflected.

Any idea whether we are doing something wrong here? Has it worked for someone else?

controller:
  componentName: "jenkins-controller"
  image: "jenkins/jenkins"
  tag: "lts-jdk11"
  imagePullPolicy: "Always"
  ...
  podAnnotations:
    cluster-autoscaler.kubernetes.io/safe-to-evict: "false"
  priorityClassName: "pre-existing-priorityclass"

Version of Helm and Kubernetes

- Helm: v3.11.3
- Kubernetes: v1.23.5

Chart version

jenkins-4.1.13

What happened?

1. Change the parameter of `priorityClassName` in `values.yaml`.
2. Run `helm upgrade`.
3. The change is not being reflected.
...

What you expected to happen?

The pod priority should change
