华为云UCS 使用策略定义库

策略实例示例

以下策略实例展示了策略定义生效的资源类型，pararmeters中定义了允许的组列表allowedGroups和允许的用户列表allowedUsers。

# IMPORTANT: Before deploying this policy, make sure you allow-list any groups
# or users that need to deploy workloads to kube-system, such as cluster-
# lifecycle controllers, addon managers, etc. Such controllers may need to
# update service account names during automated rollouts (e.g. of refactored
# configurations). You can allow-list them with the allowedGroups and
# allowedUsers properties of the NoUpdateServiceAccount Constraint.
apiVersion: constraints.gatekeeper.sh/v1beta1
kind: NoUpdateServiceAccount
metadata:
  name: no-update-kube-system-service-account
spec:
  match:
    namespaces: ["kube-system"]
    kinds:
    - apiGroups: [""]
      kinds:
      # You can optionally add "Pod" here, but it is unnecessary because
      # Pod service account immutability is enforced by the Kubernetes API.
      - "ReplicationController"
    - apiGroups: ["apps"]
      kinds:
      - "ReplicaSet"
      - "Deployment"
      - "StatefulSet"
      - "DaemonSet"
    - apiGroups: ["batch"]
      kinds:
      # You can optionally add "Job" here, but it is unnecessary because
      # Job service account immutability is enforced by the Kubernetes API.
      - "CronJob"
  parameters:
    allowedGroups: []
    allowedUsers: []
