Unable to mount FS as a non root user

I have a nginx image that runs as non root (user is nginx UID 101 GID 101 )in kubernetes. This image also has gcsfuse installed in it.

As the image runs with nginx user, I would like this user to mount a GCS bucket. When I try this, it fails

nginx@clamav-mirror-frontend-f5f6f8f8-9hlgs:/$ id
uid=101(nginx) gid=101(nginx) groups=101(nginx)

nginx@clamav-mirror-frontend-f5f6f8f8-9hlgs:/$ gcsfuse test-clamav-mirror /data

I went through this documentation and tried the following but the same result

nginx@clamav-mirror-frontend-f5f6f8f8-9hlgs:/$ gcsfuse -o rw,_netdev,allow_other,uid=101,gid=101 test-clamav-mirror /data

Is this even possible or am I missing some config ?

Figured it out.

The path that I want to mount my bucket on /data needed to be owned by ngnix user. It was previously owned by root. The moment I gave ownership to nginx it now successfully mounts.
