1.2. 为发现的托管集群自动导入

为您的 DiscoveredCluster 自定义资源创建 YAML 文件，并编辑以下示例中引用的配置：

apiVersion: policy.open-cluster-management.io/v1
kind: Policy
metadata:
  name: policy-mce-hcp-autoimport
  namespace: open-cluster-management-global-set
  annotations:
    policy.open-cluster-management.io/standards: NIST SP 800-53
    policy.open-cluster-management.io/categories: CM Configuration Management
    policy.open-cluster-management.io/controls: CM-2 Baseline Configuration
    policy.open-cluster-management.io/description: Discovered clusters that are of
      type MultiClusterEngineHCP can be automatically imported into ACM as managed clusters.
      This policy configure those discovered clusters so they are automatically imported.
      Fine tuning MultiClusterEngineHCP clusters to be automatically imported
      can be done by configure filters at the configMap or add annotation to the discoverd cluster.

                  namespace: open-cluster-management-global-set
                data:

            {{- range $dc := (lookup "discovery.open-cluster-management.io/v1" "DiscoveredCluster" "" "").items }}
              {{- /* Check for the flag that indicates the import should be skipped */ -}}
              {{- $skip := "false" -}}
              {{- range $key, $value := $dc.metadata.annotations }}
                {{- if and (eq $key "discovery.open-cluster-management.io/previously-auto-imported")
                           (eq $value "true") }}
                  {{- $skip = "true" }}
                {{- end }}

                  importAsManagedCluster: true 2
              {{- end }}
            {{- end }}

创建仅选择 local-cluster 的放置 定义，该定义是管理的 hub 集群。使用以下 YAML 示例：

apiVersion: cluster.open-cluster-management.io/v1beta1
kind: Placement
metadata:
  name: policy-mce-hcp-autoimport-placement
  namespace: open-cluster-management-global-set
spec:
  tolerations:
    - key: cluster.open-cluster-management.io/unreachable
      operator: Exists
    - key: cluster.open-cluster-management.io/unavailable
      operator: Exists
  clusterSets:
    - global
  predicates:
    - requiredClusterSelector:
        labelSelector:
          matchExpressions:
            - key: local-cluster
              operator: In
              values:
                - "true"

使用 PlacementBinding 资源连接资源。请参阅以下示例，placementRef 引用您创建的 放置，主题 引用您创建的 策略 ：

apiVersion: policy.open-cluster-management.io/v1
kind: PlacementBinding
metadata:
  name: policy-mce-hcp-autoimport-placement-binding
  namespace: open-cluster-management-global-set
placementRef:
  name: policy-mce-hcp-autoimport-placement
  apiGroup: cluster.open-cluster-management.io
  kind: Placement
subjects:
  - name: policy-mce-hcp-autoimport
    apiGroup: policy.open-cluster-management.io
    kind: Policy

要验证，请运行以下命令：

oc get policies.policy.open-cluster-management.io policy-mce-hcp-autoimport -n <namespace>
