2.6.4.2.3. fromClusterClaim function

fromClusterClaim 功能返回 ClusterClaim 资源中的 Spec.Value 的值。查看该功能的以下语法：

func fromClusterClaim (clusterclaimName string) (value map[string]interface{}, err Error)

当使用功能时，输入 Kubernetes ClusterClaim 资源的名称。如果 ClusterClaim 资源不存在，您会收到策略违反情况。查看在目标受管集群上强制执行 Kubernetes 资源的配置策略示例。platform 数据键的值是一个模板，它检索 platform.open-cluster-management.io 集群声明的值。同样，它从 ClusterClaim 获取产品和版本的值：

apiVersion: policy.open-cluster-management.io/v1

      data:
        # Configuration values can be set as key-value properties
        platform: '{{ fromClusterClaim "platform.open-cluster-management.io" }}'
