  # Example showing how to customize tolerations for different service operators
  #
  # MERGE BEHAVIOR:
  # - Custom tolerations are MERGED with the default tolerations
  # - If a custom toleration has the same KEY as a default, it OVERRIDES the default
  # - If a custom toleration has a different KEY, it is ADDED to the defaults
  #
  # Default tolerations (applied automatically unless overridden):
  #   - key: "node.kubernetes.io/not-ready"
  #     operator: "Exists"
  #     effect: "NoExecute"
  #     tolerationSeconds: 120
  #   - key: "node.kubernetes.io/unreachable"
  #     operator: "Exists"
  #     effect: "NoExecute"
  #     tolerationSeconds: 120
  operatorOverrides:
  - name: "keystone"
    # Custom tolerations for keystone operator pods
    tolerations:
    - key: "example.com/special-nodes"
      operator: "Equal"
      value: "keystone"
      effect: "NoSchedule"
    - key: "node.kubernetes.io/memory-pressure"
      operator: "Exists"
      effect: "NoExecute"
      tolerationSeconds: 300
  - name: "nova"
    # Example: Override default tolerations and add new ones
    # Result will be:
    #   1. node.kubernetes.io/not-ready (OVERRIDDEN - 600s instead of 120s)
    #   2. node.kubernetes.io/unreachable (OVERRIDDEN - 400s instead of 120s)
    #   3. node.example.com/compute (ADDED - new toleration)
    tolerations:
    - key: "node.kubernetes.io/not-ready"
      operator: "Exists"
      effect: "NoExecute"
      tolerationSeconds: 600  # Override default 120s
    - key: "node.kubernetes.io/unreachable"
      operator: "Exists"
      effect: "NoExecute"
      tolerationSeconds: 400  # Override default 120s
    - key: "node.example.com/compute"  # Add new toleration
      operator: "Equal"
      value: "true"
      effect: "NoSchedule"
  - name: "glance"

        limits:

          cpu: "1"
          memory: "2Gi"
    tolerations:
    - key: "storage-node"
      operator: "Equal"
      value: "true"
      effect: "NoSchedule"
  # Note: Operators not listed (like mariadb, neutron, etc.) will use the default tolerations
