Kubernetes 卷“的MountVolume.SetUp失败；nfs"；：装载失败：退出状态32
这是第一个问题之后的第二个问题 我正在建立一个只使用一个节点的kubernetes实验室，并学习设置kubernetes nfs。我通过以下链接逐步介绍kubernetes nfs示例： 根据“helmbert”提供的反馈，我修改了 它可以工作，我再也看不到事件“PersistentVolumeClaim未绑定：”nfs pv provisioning demo“ 我看到两个nfs busybox吊舱的状态都是“ContainerCreating”，并且从未更改为“Running”。这是因为容器图像是针对谷歌云的，如yaml中所示吗 因为我没有在这个实验室使用谷歌云，我是否必须将“图像”行替换为其他行？我的实验室只有一个节点。我需要重写上面“容器”的定义吗？我应该用什么替换“图像”行？我需要从某处下载停靠的“nfs映像”吗Kubernetes 卷“的MountVolume.SetUp失败；nfs"；：装载失败：退出状态32,kubernetes,nfs,persistent-volumes,persistent-volume-claims,Kubernetes,Nfs,Persistent Volumes,Persistent Volume Claims,这是第一个问题之后的第二个问题 我正在建立一个只使用一个节点的kubernetes实验室，并学习设置kubernetes nfs。我通过以下链接逐步介绍kubernetes nfs示例： 根据“helmbert”提供的反馈，我修改了 它可以工作，我再也看不到事件“PersistentVolumeClaim未绑定：”nfs pv provisioning demo“ 我看到两个nfs busybox吊舱的状态都是“ContainerCreating”，并且从未更改为“Running”。这是因为
