Type: Bug
Resolution: Not A Defect
Priority: Blocker
Component/s: kubernetes-plugin
Labels:
- issue-exported-to-github
Environment:
Jenkins: 2.385
Jenkins plugins:
- Kubernetes: 3743.v1fa_4c724c3b_7
- Kubernetes Client API: 5.12.2-193.v26a_6078f65a_9
- Kubernetes Credentials: 0.9.0

I'm trying to create a pod template using the podTemplate() pipeline step with the below code:

def image = "jenkins/inbound-agent"

podTemplate(cloud: 'kubernetes', activeDeadlineSeconds: 7200,
            name: 'mytest', namespace: 'default',
            containers: [
                containerTemplate(name: 'jnlp', image: image,
                    envVars: [envVar(key: 'AAAA', value: 'bbbb')], resourceLimitCpu: '1', resourceLimitEphemeralStorage: '', resourceLimitMemory: '4Gi', resourceRequestCpu: '1',
                    ttyEnabled: true
                )
            ]
) {
    node(POD_LABEL) {
        stage('my-build') {
            container('jnlp') {
                echo POD_CONTAINER
                //sh "echo hello from $POD_CONTAINER"
                //sh 'env|sort'
            }
        }
    }
}

It works properly, creates the pod, prints the container name (jnlp) just fine. However, when I attempt to use any of the commented out "sh" calls, then I get the below exceptions (notice the HTTP 403 forbidden issue at the end):
