[BUG] matrix container - default permissions issues

[tylerstraub]

Greetings. I am going through the process of attempting a Matrix Synapse implementation using the A75G Docker package on the Unraid platform.

The first thing I have noticed is that there seems to be some sort of permissions issue happening out of box with the /data volume mapping.

I'm going through the process of troubleshooting it now myself and haven't solved it just yet. But I wanted to report what I'm seeing here in case the maintainer wants to try to adjust the package or add some additional setup instructions.

Thank you!

Here was how I resolved the issue:

Made sure that the folder ownership was correct (I'm not sure if this step was necessary):
chown -R 991:991 /mnt/user/appdata/matrix

Edited my log.config file that matrix autogenerated in the /data volume and changed the path of the homeserver.log file to go inside of /data:

ex

        filename: /data/homeserver.log     

Restarted the Docker container, this resolved my issue. I think the following Github issue has some relevant data as to how this may have occurred: matrix-org/synapse#9970

Hope this helps!

chown -R 991:991 /mnt/user/appdata/matrix

This solved my issue as well. No files were being generated for me to edit until the permissions issue was resolved. Thanks for posting.
