I think this has something to do with the Dockerfile not properly giving the user permissions to write and store data. Can you share the dockerfile?

here is the dockerfile which is being used by docker-compose. it works when running docker-compose locally

docker-compose.yml: harmony/docker-compose.yml at main · bugzilla/harmony
dockerfile: harmony/Dockerfile at main · bugzilla/harmony

Hello,

Please try setting a RAILWAY_RUN_UID service variable to 0

Best,
Brody

it did something.

It changed the error to: Effective UID must be 10001!

Hello,

You would need to remove that artificial limitation as your app does need to run as root (UID 0) to read and write with the volume, as the volume is mounted as root and that is not configurable.
