I would like to mount an AWS EFS location with the efs driver which internaly uses nfs. Now the question is: How do I automatically mount a location with specific uid and gid? With sshfs e.g. I would just define uid, gid as mount options, but it's not implemented in nfs.
A regular Linux NFS server would do the trick with the following combination of
man 5 exports:
all_squash- Map all uids and gids to the anonymous user.
anongid- These options explicitly set the uid and gid of the anonymous account.
With Amazon EFS you'll need locally mounted
bindfs layer to change permissions as the server export options cannot be changed.
Please take a look at this Unix & Linux StackExchange question.
It looks like the
bindfs currently lacks ability to map all users/groups into one but I guess it could be added to the code quite easily.
