      Description

      I have this in my pipeline:

      def label = "mypod-${UUID.randomUUID().toString()}"
      podTemplate(label: label, yaml: """
      apiVersion: v1
      kind: Pod
      metadata:
        labels:
          some-label: some-label-value
      spec:
        containers:
        - name: jnlp
          image: 1234567890.dkr.ecr.us-east-1.amazonaws.com/jenkins-slave:1.0.0
          command:
          - /usr/local/bin/jenkins-slave
          tty: true
          securityContext:
            runAsUser: 10000
            allowPrivilegeEscalation: false
      """
      ) {
          node (label) {
            container('jnlp') {
              sh "hostname"
              sh "mvn --version"
            }
          }
      }
      
      

      When I execute this, i expect that the maven version from my custom jnlp image gets printed, instead I get the following error:

      If you see the message above, it is still provisiong the jnlp:alpine image and using that as default.

       

      Can you please correct me if my usage is incorrect and the right way to override jnlp
