如何为kubernetes中的共享卷授予完全权限

Question

I have a container which is using shared volume with host. I want to give it a full permissions. At present, it is:

ls -l
drwxr-xr-x 8 user user 4096 Aug  9 04:47 Data

But I want it to be:

ls -l
drwxrwxrwx 8 user user 4096 Aug  9 04:47 Data

I have a below deployment file:

----
----
spec:
  containers:
  - name: logger
    image: logger_image
    volumeMounts:
    - mountPath: /Data
      name: Data-files
    securityContext:  
      privileged: true

 volumes:
  - name: Data-files
    hostPath:
      path: /home/user/Documents/Data

----
----

I have even set it as privileged but still, the volumes do not have full permissions. What should I add in deployment file to make the volume full permissions?

Thanks

Answer 1

Your permissions on /home/user/ or /home/user/Documents/ folders don't allow the process' owner (of logger_image) to access the folder and write.

Try to create /Data (on your root) and set the proper permissions.

Answer 2

I resolved this issue by mentioning the appropriate commands to give full permissions to that directory in the Dockerfile itself.

In the dockerfile:

RUN mkdir -p /Data
RUN chmod 777 -R Data/

and then later used the same kubernetes deployment file and it worked fine with full permissions.

Thanks
