Hmm, I lost the correct indentation in the message, but the yaml 
indentation is correct in my project.

persistentVolumeClaimWorkspaceVolume produced emptyDir volume instead of PVC

2020-04-28 Thread David Warburton
Hi mailing list,

I'm building a pipeline for neural net training that needs to operate on 
around 650G of data using the kubernetes plugin to run agents in pods. In 
between builds I'd like the data to stick around in a persistent volume for 
the workspace. It seems like the persistentVolumeClaimWorkspaceVolume is 
perfect for this, but  the way I have it configure is not working.

Jenkinsfile:

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'
 }
   }
 }
}

jenkins/pv-pod.yaml:

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


I have already defined the PersistentVolumeClaim and applied it to the same 
namespace the jenkins pods are running in (default)
pv-claim.yaml:

apiVersion: v1
kind: PersistentVolumeClaim
metadata:
 name: workspace
spec:
 accessModes:
 - ReadWriteOnce
 resources:
 requests:
 storage: 100Gi

Is there a mistake in this setup or have I misunderstood how this is 
supposed to work?

Thanks
