apiVersion: v1
data:
  admissionController.filtering.generateUniqueAppId: "true"
  queues.yaml: |
    partitions:
      - name: default
        placementrules:
          - name: provided
            create: false
          - name: tag
            value: namespace
            create: true
        queues:

sleep.yaml

apiVersion: v1
kind: Pod
metadata:
  labels:
    app: sleep
    queue: "root.default"
  name: task1
spec:
  schedulerName: yunikorn
  restartPolicy: Never
  containers:
    - name: sleep-30s
      image: "alpine:latest"
      command: ["sleep", "30"]
      resources:
        requests:
          cpu: "100m"
          memory: "500M"

Execute

k create -f sleep.yaml

and get an error:

The Pod "task1" is invalid: metadata.labels: Invalid value: "default-": a valid label must be an empty string or consist of alphanumeric characters, '-', '_' or '.', and must start and end with an alphanumeric character (e.g. 'MyValue',  or 'my_value',  or '12345', regex used for validation is '(([A-Za-z0-9][-A-Za-z0-9_.]*)?[A-Za-z0-9])?')
