### Description

I install rocket chat on a Docker container, and get this error when using FileSystem (I was on GridFS by default but want to switch to FS due to a large MongoDB database size):

`LocalStore: cannot set store permissions 0744 (EPERM: operation not permitted, chmod '/app/files')`

The problem is that the folder inside the docker container has UID 1000. I can not change it with chown or chmod because the operation is not permitted. I tried to create the folder before I bind the volume and it has the rocketchat UID when I create but as soon as I bind the volume the UID changes to 1000.
