[kubernetes-plugin] Define pod with yaml

[Ram Kamath]

Dear Jenkins Users,

I am trying to make use of the pod creation with yaml feature introduced in V1.6. I am using the example pipeline on the GitHub page [HERE]. I always get an exception. Could anybody shed some light on my possible mistake?

my jenkinsfile is 

pipeline {

  agent {

    kubernetes {

      label 'mypod'

      defaultContainer: 'jnlp'

      yaml """

apiVersion: v1

kind: Pod

metadata:

  labels:

    app: test

spec:

  containers:

  - name: maven

    image: maven:alpine

    command:

    - cat

    tty: true

  - name: busybox

    image: busybox

    command:

    - cat

    tty: true

"""

    }

  }

  stages {

    stage('Run maven') {

      steps {

        container('maven') {

          sh 'mvn -version'

        }

        container('busybox') {

          sh '/bin/busybox'

        }

      }

    }

  }

}

And the exception is

I am using plugin version 1.6 and Jenkins 2.107.2

there's a typo in the example 

defaultContainer: 'jnlp'

should be

defaultContainer 'jnlp'
