See documentation for the latest supported version 3 or the latest supported version 4.10.4. 暂停机器配置池
在这个 Canary rollout 更新过程中，在使用 OpenShift Container Platform 集群的其余集群标记了节点并创建机器配置池 (MCP) 后，您会暂停这些 MCP。暂停 MCP 可防止 Machine Config Operator (MCO) 更新与该 MCP 关联的节点。
注意
暂停 MCP 还会暂停 kube-apiserver-to-kubelet-signer 自动 CA 证书轮转。在自安装日期起的 292 天生成新 CA 证书，旧证书将从安装日期的 365 天后删除。请参阅红帽 OpenShift 4 中的了解 CA 证书自动续订，以了解您在下一次自动 CA 证书轮转前的时间。确保发生 CA 证书轮转时，池已被取消暂停。如果 MCP 暂停，则不会发生证书轮转，这会导致集群降级，并导致多个 oc 命令失败，包括但不限于 oc debug、oc logs、oc exec 和 oc attach。
暂停 MCP：
对您要暂停的 MCP 进行补丁：
