13.6.2. 放置示例

您需要通过在该命名空间中创建一个 ManagedClusterSetBinding 来最少将一个 ManagedClusterSet 绑定到一个命名空间。注：您需要在 managedclustersets/bind 的虚拟子资源上对 CREATE 进行基于角色的访问权限。请参见以下示例：

您可以使用 labelSelector 选择 ManagedClusters。请参阅以下示例，其中 labelSelector 仅与带有标签 vendor: OpenShift 的集群匹配：

apiVersion: cluster.open-cluster-management.io/v1alpha1
kind: Placement
metadata:
  name: placement1
  namespace: ns1
spec:
  predicates:
    - requiredClusterSelector:
        labelSelector:
          matchLabels:
            vendor: OpenShift

apiVersion: cluster.open-cluster-management.io/v1alpha1
kind: Placement
metadata:
  name: placement1
  namespace: ns1
spec:
  predicates:
    - requiredClusterSelector:
        labelSelector:
          matchLabels:
            vendor: OpenShift

您可以使用 claimSelector 选择 ManagedClusters。请参阅以下示例，其中 claimSelector 仅与带有 us-west-1 的 region.open-cluster-management.io 的集群匹配：

apiVersion: cluster.open-cluster-management.io/v1alpha1
kind: Placement
metadata:
  name: placement2
  namespace: ns1
spec:
  predicates:
    - requiredClusterSelector:
        claimSelector:
          matchExpressions:
            - key: region.open-cluster-management.io
              operator: In
              values:
                - us-west-1

apiVersion: cluster.open-cluster-management.io/v1alpha1
kind: Placement
metadata:
  name: placement2
  namespace: ns1
spec:
  predicates:
    - requiredClusterSelector:
        claimSelector:
          matchExpressions:
            - key: region.open-cluster-management.io
              operator: In
              values:
                - us-west-1

您可以从特定的 clusterSets 中选择 ManagedClusters。请参阅以下示例，其中 claimSelector 仅与 clusterSets: clusterset1 clusterset2 匹配：

apiVersion: cluster.open-cluster-management.io/v1alpha1
kind: Placement
metadata:
  name: placement3
  namespace: ns1
spec:
  clusterSets:
    - clusterset1
    - clusterset2
  predicates:
    - requiredClusterSelector:
        claimSelector:
          matchExpressions:
            - key: region.open-cluster-management.io
              operator: In
              values:
                - us-west-1

apiVersion: cluster.open-cluster-management.io/v1alpha1
kind: Placement
metadata:
  name: placement3
  namespace: ns1
spec:
  clusterSets:
    - clusterset1
    - clusterset2
  predicates:
    - requiredClusterSelector:
        claimSelector:
          matchExpressions:
            - key: region.open-cluster-management.io
              operator: In
              values:
                - us-west-1

选择所需的 ManagedClusters 数量。请参阅以下示例，其中 numberOfClusters 为 3 ：

apiVersion: cluster.open-cluster-management.io/v1alpha1
kind: Placement
metadata:
  name: placement4
  namespace: ns1
spec:
  numberOfClusters: 3
  predicates:
    - requiredClusterSelector:
        labelSelector:
          matchLabels:
            vendor: OpenShift
        claimSelector:
          matchExpressions:
            - key: region.open-cluster-management.io
              operator: In
              values:
                - us-west-1

apiVersion: cluster.open-cluster-management.io/v1alpha1
kind: Placement
metadata:
  name: placement4
  namespace: ns1
spec:
  numberOfClusters: 3
  predicates:
    - requiredClusterSelector:
        labelSelector:
          matchLabels:
            vendor: OpenShift
        claimSelector:
          matchExpressions:
            - key: region.open-cluster-management.io
              operator: In
              values:
                - us-west-1
