红帽全球峰会12.2. 关于为 GitOps ZTP 自动创建的 ClusterGroupUpgrade CR
TALM 有一个名为 ManagedClusterForCGU 的控制器，它监控 hub 集群上的 ManagedCluster CR 的 Ready 状态，并为 GitOps Zero Touch Provisioning (ZTP) 创建 ClusterGroupUpgrade CR。
对于没有应用 ztp-done 标签的 Ready 状态中的任何受管集群，ManagedClusterForCGU 控制器会在 ztp-install 命名空间中创建一个带有在 GitOps ZTP 进程中创建的关联 RHACM 策略的 ClusterGroupUpgrade CR。然后，TALM 会修复自动创建 ClusterGroupUpgrade CR 中列出的一组配置策略，将配置 CR 推送到受管集群。
如果集群变为 Ready 时，没有用于受管集群的策略，则会创建一个没有策略的 ClusterGroupUpgrade CR。完成 ClusterGroupUpgrade 受管集群后，受管集群被标记为 ztp-done。如果要对该受管集群应用策略，请手动创建一个 ClusterGroupUpgrade 作为第 2 天操作。
