      I've created a build step with the following pod template (with some elided content):

       

      podTemplate(label: label, yaml: """
apiVersion: v1
kind: Pod
spec:
  containers:
    - name: db
      image: mdillon/postgis:10-alpine
    - name: elasticsearch
      image: docker.elastic.co/elasticsearch/elasticsearch:6.1.3
      env:
        - name: discovery.type
          value: single-node
    - name: memcached,
      image: memcached:1.5.10-alpine
    - name: redis,
      image: redis:4.0.6-alpine
    - name: web,
      image: ${info['image']}
""") {
    node(label) {
        // etc
    }
}

      When I attempt to run my pipeline, it throws

      Also:   hudson.AbortException: Container Names MUST match RFC 1123 - They can only contain lowercase letters, numbers or dashes: memcached,, redis,, web,

      Just to test things, I used println to output the full yaml string and tossed that at kubectl apply -f which happily accepted the file and deployed my pod.

       

      Am I missing something here, or is the plugin just failing to (for some reason) parse two of my containers' names but not the others?
