Allow the UID/GID to be changed

[derekoharrow]

I have a CIFS/SMB volume mounted on my docker host, accessed by many of my containers. For all the other containers, I can specify a UID/GID in the docker-compose file so that they have read/write access to this volume.
How do you specify the UID/GID for NextCloud? As it stands, it can read the volume but doesn't have write access.
Thanks

I see in the instructions that you can do the following:
docker exec --user www-data CONTAINER_ID php occ
But how do you specify the user in the docker-compose.yml file?

There is currently no way to change the UID and GID. I think this is supported by the parent image. But the entrypoint script does not properly support it.

this should be possible. this works for me:
docker run --user 1234 -p 8080:80 --sysctl net.ipv4.ip_unprivileged_port_start=0 nextcloud

@tilosp Thanks for your comment. Unfortunately I don't seem able to reproduce this.

My host system has a user with the ID 1000. When I run the following command, the files created in the /storage/docker/nextcloud/config belong to www-data root.

docker run \
-d \
--user 1000 \
--name=nextcloud \
--network=private-network \
-e NEXTCLOUD_DATA_DIR=/data \
-v /storage/docker/nextcloud/config:/var/www/html \
-v /storage/docker/nextcloud/data:/data \
nextcloud

Are you sure this worked on your end?

@caillou I'm using the suggestion by @tilosp via docker-compose. I can confirm that files uploaded to Nextcloud get the UID/GID as set in docker-compose.yaml. However, I converted an existing installation to this and didn't try upgrading the container to a newer version yet, so I cannot say anything about what permissions Nextcloud's own files will receive then.

when I use user: "${uid}:${guid}" field in a compose file with docker swarm (sudo docker stack deploy --compose-file...) I get permissions errors:

Can you tell me how you set the UID/GID in docker-compose?
