调试挂起状态的pod

Question

如何调试挂起状态的pod？我正在使用k8ssandra https://k8ssandra.io/docs/创建Cassandra集群。它使用helm文件。我创建了一个3节点集群，并在本地values.yaml文件中将size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

按照Arghya的描述，最好的方法是检查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
