kubernetes - 调试卡在挂起状态的 pod
问题描述
如何调试卡在挂起状态的 pod？我正在使用k8ssandra https://k8ssandra.io/docs/创建一个Cassandra集群。它使用helm文件。我创建了一个 3 节点集群并将size本地values.yaml文件中的值更改为 3 以创建一个 3 节点集群 - https://github.com/k8ssandra/k8ssandra/blob/main/charts/k8ssandra-cluster/values.yaml

解决方案
Arghya 描述的最佳方法是检查 pod 的事件。
kubectl describe pod k8ssandra-dc1-default-sts-1
您还可以检查 pod 的日志：
kubectl logs k8ssandra-dc1-default-sts-1
