ownCloud Docker + local storage (NFS): Cannot write to existing /home directories

I have an ownCloud server (Docker) running.
I mounted my /home directories as volumes. I can see them attach them as Local storage. The only issue I’m experiencing is, it doesn’t have correct permission to write on the existing /home directories. I created a new directory with www-data and it works. Is there any possibility to NOT change the owners to www-data and use root instead?


i’m not sure if this is an ownCloud specific question or if this is more related to Docker and thus could be maybe require to be placed into a Docker support forum.
