kubernetes 为什么这些pod的状态为“初始化:0/2”

我运行命令“helmupgrade”来应用我对config.yaml文件所做的更改。但是,现在我有两个处于Init:0/2状态的Pod,其中有一个经常性的FailedCreatePodSandBox错误。对下一步该怎么做有什么建议吗?
kubectl get pod:

kubectl describe pods命令中可以看到,pod有两个init容器。这些init容器以连续的顺序运行,这意味着第二个容器只有在第一个容器完成时才开始。
只有在所有init容器成功运行后,主容器才会启动。指示pod首先具有状态Init:0/2,这意味着2个初始化容器中的0个已完成。
在第一个init容器运行后,它将进入Init:1/2。但您可能永远看不到这一点,这取决于这些init容器完成任务所需的时间。
