【问题描述】：

我想在 pod 内部检查图像内部存在的缺陷，但出现以下错误。正如我在描述中验证的那样，容器的名称是正确的。我还能做些什么来获得集群中的连接？

命令：kubectl exec -it -c 气流控制台 -n 气流气流控制台-xxxxxxx-xxxxxx bash

error: unable to upgrade connection: container not found ("airflow-console")

命令：kubectl describe pod/airflow-console-xxxxxxx-xxxxx -n 气流

【问题讨论】：

看起来您的 pod 没有运行。你有kubectl get po airflow-console-xxxxxxx-xxxxx -n airflow的输出吗？
您能否发布完整的kubectl describe pod/airflow-console-xxxxxxx-xxxxx -n airflow 以及您用于创建它的清单（yaml）？
需要更多有关 pod 状态的信息来帮助调查，您的 pod 清楚地表明它处于错误状态。

标签： kubernetes kubectl azure-aks

【解决方案1】：

这一行

Warning  BackOff    2m15s (x178 over 36m)  kubelet, aks-test  Back-off restarting failed container

显示您的 pod/容器处于故障状态。这将阻止您在容器中执行命令，因为它不是活着的。

要了解您的 pod/容器为何处于错误状态，您应该查看故障容器的日志

kubectl logs -n airflow airflow-console-xxxxxxx-xxxxx -c airflow-console

或从前一个失败的容器中注销。（有时会有所帮助）

kubectl logs -n airflow airflow-console-xxxxxxx-xxxxx -c airflow-console -p

这解释了用户无法执行到容器中的主要原因。
