Only root can write to OSX volumes / Can't change permissions within about docker-machine-nfs

[kusmierz]

edit /etc/exports and find line something like this:

/Users 192.168.99.100 -alldirs -mapall=501:20

and change to:

/Users 192.168.99.100 -alldirs -maproot=0

or just try to run

docker-machine-nfs default -f --nfs-config="-alldirs -maproot=0"

Hey @evbo ,

Can you share how you configured nfs for your box. because in the comment you share the user did do it with -maproot=0 , which is now possible since #17

[tonivdv]

Were you able to test this?

[evbo]

sorry, I'm not entirely sure what it means to set maproot. However, I did attempt to apply what I thought it meant to my local machine but it had no affect. Is there a more explicit guide for adding that setting? It's possible I just misread it as I have never edited those configurations on my mac before, nor do I know how to test them other than it works or not. Thanks for the follow up and sorry again for being belated on the reply!

Hello,

If I use the default configuration (-alldirs -mapall=501:20), the postgres user from the official postgres Docker image can not write to the OS X file system (permission denied).

If I use the -alldirs -maproot=0 NFS configuration, then all is fine, the user from Docker can write to my local file system, but the file now belong to user 999. In the Finder, there is a one-way sign on the directory icon, meaning that the file does not belong to me.

Is there something I miss here?
Thank you for your help!

Hey @tuscland ,

Got users that had the same issue with mysql images. I'm not using shared volumes with mysql on os X. I use data containers and then it's no issue.

Not sure if that's helpful for you, but I ignore how to make it work like you describe :(

Cheers

Thanks, I'll try data containers!
