Google Cloud Storage moun + nginx user

Question

I'm able to mount my Google Cloud Storage with gcsfuse but I need nginx to write in it. How do I do that? I've added nginx to the mounting users group and nothing. Probably because the mount has 755 on all folders? Any idea would be appreciated.

By default only the user who mounted the file system has access to it. As per the documentation you can use "-o allow_other" to allow other users to access the file system.

gcsfuse also allows you to directly set owners for the inodes using the --uid and --gid flags.
