Hi,
I’m trying my best to setup Nextcloud on my mediaserver, but I cannot work out the permissions to my data folder.
My setup is as follows: proxmox server openmediavault VM with 8tb disk and nfs shares debian mediaserver with docker compose (including nextcloud docker)
the nfs share is set to 775. I linked it in my debian server through /etc/fstab. I can write to the folder without a problem.
In my docker compose file i linked /mnt/photos:/photos to the nextcloud container. When i login to my container i cannot write files to the folder.
When i change the share to 777, i can write files, but nextcloud setup stops and says my permissions are wide open, so it won’t continue the setup.
I turn it back to other:read/execute and the container cannot write to the folder anymore.
What am i doing wrong?
Nextcloud uses the www-data user internally. Id is 33. You should be able to “chown 33 dirname” on the nfs server. That may work?
I want to try that, but i’ve got to add: i want to access this folder from my desktop too. i added it the same way in /etc/fstab and it worked instantly
That’s what group permissions are for. You can add yourself to the www-data group and
chown www-data:www-data path. Then you and the container should be able to operate on the contents.Do not forget to log out and log back in after you add yourself to a new group. Your desktop environment is a program, and it won’t know about the update until you spawn a new graphical shell with the updated permissions.
Or just start a new login shell.

Try telling Docker its rw explicitly:
- /mnt/photos:/photos:rw
It should be rw by default but I can’t see what else could be happening. What account runs docker? What account runs nextcloud inside the container?
how can i check which accounts are used? I think my normal user account sets up docker, with uid & gid = 1000. I don’t think i created an account in the container so probably root.
The official NC docker container uses the “www-data” internally to run the services. This will get important if you ever want to run tasks via “docker compose exec”.
When I run:
docker exec -it nextcloud bashI get:root@nextcloud:/var/www/html#, does this mean it uses www?
You need to allow nextcloud to control the file permissions. You can do this with the no_root_squash option in the /etc config file
I added this! Your solution + chmod 0770 on my folder made it work. Thanks for helping!
