我有一个k8s cronjob,它由一个初始化容器和一个pod容器组成。如果init容器失败,则主容器中的Pod将永远不会启动,并且会无限期地停留在“PodInitializing”中。
我的意图是,如果init容器失败,则作业将失败。

最佳答案
为了弄清楚这一点,我将运行以下命令:kubectl get pods
-如果需要,添加 namespace 参数。
然后复制 pods 名称并运行:kubectl describe pod {POD_NAME}
那应该给你一些信息,说明为什么它停留在初始化状态。
关于kubernetes - pod 无限期陷入PodInitializing状态,我们在Stack Overflow上找到一个类似的问题:https://stackoverflow.com/questions/53314770/
