ClusterD
- 通过如下命令查看K8s集群中MindCluster ClusterD的Pod，需要满足Pod的数量为3，STATUS为Running，READY为1/1。
kubectl get pods -n mindx-dl -o wide | grep clusterd
回显示例：
clusterd-84d8ffcc44-frljq 1/1 Running 0 4h44m 192.168.243.227 ubuntu <none> <none> clusterd-84d8ffcc44-rm885 1/1 Running 0 4h44m 192.168.243.199 ubuntu <none> <none> clusterd-84d8ffcc44-wst6p 1/1 Running 0 4h44m 192.168.243.197 ubuntu <none> <none>
- 执行以下命令，分别查询MindCluster ClusterD的3个Pod日志。
kubectl logs -f -n mindx-dl {MindCluster ClusterD组件的Pod名字}其中1个Pod会被选举成leader，执行集群资源管理相关业务，日志示例如下：[INFO] 2024/06/11 12:19:59.843723 CST 1 hwlog@v0.10.12/api.go:105 cluster-info.log's logger init success W0611 12:19:59.843804 1 client_config.go:617] Neither --kubeconfig nor --master was specified.

另外两个为备份Pod，日志示例如下：[INFO] 2024/06/11 12:20:00.321361 CST 1 hwlog@v0.10.12/api.go:105 cluster-info.log's logger init success W0611 12:20:00.321445 1 client_config.go:617] Neither --kubeconfig nor --master was specified.
