persistentVolumeClaimWorkspaceVolume produces emptyDir volume instead of PVC volume when used in Declarative pipelines

Issue Type:	Bug
Assignee:	Unassigned
Components:	kubernetes-plugin
Created:	2020-05-04 21:10
Priority:	Minor
Reporter:	david warburton

I have this feature working in a scripted pipeline but when I tried to use it in a declarative pipeline it would never create the workspace volume as a persistent volume claim, it would only mount "emptyDir" volumes for the workspace.

The declarative pipeline I'm using is

 
                                                                pipeline {
 agent {
   kubernetes {
     yamlFile 'jenkins/pv-pod.yaml'
     defaultContainer 'tree'
   }
 }
 options {
   podTemplate(workspaceVolume: persistentVolumeClaimWorkspaceVolume(claimName: 'workspace', readOnly: false))
 }
 stages {
   stage('read workspace') {
     steps {
       echo 'current env'
       sh 'env'
       sh '/usr/bin/tree'
       echo 'previous env'
       sh 'cat old-env.txt || true'
       sh 'env > old-env.txt'
     }
   }
 }
}
 
                                                            

With a 'pv-pod.yaml' file with these contents

 
                                                                apiVersion: v1
kind: Pod
spec:
 containers:
 - name: tree
   image: iankoulski/tree
   command:
   - /bin/cat
     tty: true
 
                                                            

This is in kubenernetes-plugin version 1.25.3.
