检查集群健康状况

本页面适用于平台管理员。

本页面介绍如何检查集群中节点、系统 Pod 和网络连接的运行状况。

使用 Actl 检查集群运行状况

运行以下命令以检查集群的运行状况：

actl clusters baremetal check cluster CLUSTER_NAME --kubeconfig=ADMIN_KUBECONFIG

该命令会检查以下内容：

  • 集群中节点的运行状况，例如 kubelet 运行状态、containerd 状态、磁盘容量和注册表镜像可达性等。
  • 如果集群是管理员集群，则 anthos-cluster-operator 等裸机系统 Pod 的运行状况。
  • 节点之间的网络连接，例如主节点之间的 L2 连接。

以下是成功的健康检查的示例：
