data volume permissions

[fsaintma]

Hi

When I launch your Docker image with a volume to map the JanusGraph data directory on my computer (the directory on my computer don't exist yet) I obtain this result and the storage is not initialized correctly

$ docker run --rm --name janusgraph-default -v ${PWD}/graph:/var/lib/janusgraph docker.io/janusgraph/janusgraph:latest
chown: changing ownership of '/var/lib/janusgraph': Operation not permitted
chmod: changing permissions of '/var/lib/janusgraph': Operation not permitted
waiting for storage...

$ ls -la
drwxr-xr-x  2 root     root      4096 mai   27 12:06 graph

The only workaround I found is to create/modify manually the directory before the Docker command with the good permissions (uid/gid = 999).
Could we have a directory initialized with the good permissions ?
Thanks for your help.
Best regards.
