    • Type: Bug
    • Resolution: Unresolved
    • Priority: Minor
    • Component/s: kubernetes-plugin
    • Environment:
      Jenkins 2.346.3 and 2.303.3
      Kubernetes plugin 3704.va_08f0206b_95e and 1.31.3

      Steps to reproduce:

      1. Create a pod template with a pod level environment variable
      2. Create a pipeline job with
        1. Inherit from the template in 1
        2. Add another container and set it is as the default container
        3. Add a global environment section container the SAME key value pair as the pod  template env var
        4. Add a stage using the default container (no container section, just steps) and dump the env
        5. Add another stage explicitly within a container() section with the container from step 2 and dump the env
      3. When running the pipeline, you will notice that the env var will print from the stage in step 5 above but NOT from step 4

      Example pipeline:

      pipeline {
    agent {
        kubernetes {
            inheritFrom "mypodtemplate"
            defaultContainer 'mycontainer'
            yaml '''
spec:
  containers:
  - name: mycontainer
    image: ubuntu:latest
    command: [cat]
    tty: true
                '''
        }
    }
    environment {
        // use the SAME key value pair in the pod template env vars section
        ENV_VAR = 'foo'
    }
    stages {
        stage("ENV_VAR PRESENT here") {
            steps {
                container('mycontainer') {
                    sh """
                        env
                    """
                }
            }
        }
        stage("ENV_VAR NOT PRESENT here") { 
            steps {
                sh """
                    env
                """
            }
        }
    }
}

      Template:

      clouds:
  - kubernetes:
  ...
      templates:
      ...
      - envVars:
        - envVar:
            key: "ENV_VAR"
            value: "foo"
        inheritFrom: "jnlp"
        label: "mypodtemplate"
        name: "mypodtemplate"
        yamlMergeStrategy: "override"
