为常见。 4.Failed。这个状态下，Pod 里至少有一个容器以不正常的状态（非 0 的返回码）退出。这个状态的出现，意味着你得想办 法 Debug 这个容器的应用，比如查看 Pod 的 Events 和日志。 5.Unknown。这是一个异常状态，意味着 Pod 的状态不能持续地被 kubelet 汇报给 kube-apiserver，这很有可能是主从 节点（Master 和 Kubelet）间的通信出现了问题。 47 K8s技术在H3Cloud OS中的应用介绍 首先我们可以查看到当前Pod的状态是Pending，Containers的Reason为ContainerCreating。 然后重点查看Events里面的事件信息，这里列出来的无法启动的原因为挂载共享存储失败，所以我们接下来就需要查看共 享存储的配置了。 48 www.h3c.com Confidential 秘密 48 48 K8s技术在H3Cloud
