[JENKINS-50664] added missing fixed jenkins slave labels

[antoniaklja]

Regarding following issue https://issues.jenkins-ci.org/browse/JENKINS-50664

Jenkins slave pod doesn't have fixed label which can be used for generic NetworkPolicy to secure master-slave communication within Kubernetes namespace.

Example policy for JNLP access:

apiVersion: networking.k8s.io/v1
kind: NetworkPolicy
metadata:
  name: jenkins
  namespace: XXX
spec:
  podSelector:
    matchLabels:
      run: jenkins-master-XXX
  policyTypes:
  - Ingress
  ingress:
   - from:
    - podSelector:
        matchLabels:
          jenkins/slave: true
    ports:
    - protocol: TCP
      port: 50000

ofc it might be different label but should be present on every jenkins slave Pod.

were you trying to write a test that fails to show the issue ? because the test is passing

[carlossg]

ah sorry, missed the one line

[hrishin]

Expecting default labels as follow, right?

labels:
   jenkins : 'slave'

rather than

labels:
   jenkins/slave : true

I think #322 is doing the correct fix for this one

Fixed in #325
