kubernetes:部署失败来自守护程序的错误响应：OCI运行时创建失败：

我已经在raspberry pi上建立了一个两节点集群，并且正在尝试建立一个ghost博客平台。我创建了一个部署，我看到容器正在崩溃，状态为“CrashLoopback”。非常感谢您对疑难解答的任何帮助。谢谢

我看到它与权限有关，但不确定这些权限是什么。以下是PV和PVC的输出

权限拒绝错误与以下操作有关：

mkdir/var/lib/docker/overlay2/c83d0b7a7a4e0f576c3393907aad3d54b4657d6520ca47fbd201e1e3b3a9fe3/merged/var/lib/ghost/content:权限拒绝

从您提供的信息来看还不清楚，但是如果我不得不猜测您正在尝试在NFS共享上创建一个目录的话。如果是这样，您很可能没有NFS服务器对该路径的写入权限。

。是的。情况似乎是这样。我将etc/exports更改为/mnt/ud hdd 192.168.178.0/24（rw、sync、no_root\u squash）以提供根访问。现在我得到一个不同的错误。我更新了问题部分的错误经过进一步调查，我发现应用程序正在写入文件夹，但错误是由应用程序引起的…是的。情况似乎是这样。我将etc/exports更改为/mnt/ud hdd 192.168.178.0/24（rw、sync、no_root\u squash）以提供根访问。现在我得到一个不同的错误。我更新了问题部分的错误经过进一步调查，我发现应用程序正在写入文件夹，但错误是由应用程序引起的。
