没有写到emptyDir的权限 [英] Do not have permission to write to emptyDir

问题描述

我已将带有存储介质的emptyDir卷安装到Pod.然后，我登录到Pod，并尝试在该卷路径中创建文件，但出现了权限被拒绝的错误.

I have mounted a emptyDir volume with memory medium to a pod. Then I logged into the pod and tried to create a file in that volume path but I got a permission denied error.

touch a.txt
touch: cannot touch `a.txt': Permission denied

我使用的用户是root.可能是什么原因?

User I used is root. What could be the reason for that?

推荐答案

添加:z或:Z作为您的安装路径的解决方法，以使其与selinux正常工作:

Add :z or :Z as a workaround to your mount path to work properly with selinux:

volumeMounts:
- name: etcd-storage
  mountPath: /var/etcd/data:z
