Conflicts with Vagrant nfs mounts about docker-machine-nfs HOT 7 CLOSED

Hi Sebastian!
Could you please do the following:

• Clear exports file
• Run your Vagrant project with nfs mount, so it will create exports entry
• Post contents of exports file here

I want to see vagrants configuration, but don't have it installed

from docker-machine-nfs.

Hey @sebas5384 ,

Do you know what the default ip vagrant is using? Because exports conflict can happen without vagrant too if you use multiple docker-machine boxes. The thing with docker-machine is that it doesn't lock the ip address to a box (see docker/machine#1709). So it could be that when you start vagrant and later machine (and vice-versa) the ip changes constantly.

What I do to prevent this is following work around (docker/machine#1709 (comment)).

Try this and let us know.

That being all said, the management of the /etc/export in docker-machine-nfs is very basic, so it can be improved to avoid such things. But for for our (Adlogix/Adsdaq) needs it's not high priority.

Cheers

@krasilich and @tonivdv thanks your quick response!!

@krasilich here's my /etc/exports file when I have my vagrant's projects running.

$ cat /etc/exports
# VAGRANT-BEGIN: 501 6991d57f-1e23-42a1-a13a-d14d18659ec0
"/Users/sebas/Virtual/projects/myprojectwithvagrant" 192.168.22.11 -alldirs -mapall=501:20
# VAGRANT-END: 501 6991d57f-1e23-42a1-a13a-d14d18659ec0

@tonivdv I'll try to do that and I'll let you know.

Again thanks.

I tried to create a new machine with different CIDR, "192.168.98.1/24" instead of "192.168.22.1/24" like my vagrant's projects do:

$ docker-machine create -d virtualbox --virtualbox-hostonly-cidr "192.168.98.1/24" default98
$ docker-machine start default98
(default98) Starting VM...
Started machines may have new IP addresses. You may need to re-run the `docker-machine env` command.

$ eval "$(docker-machine env default98)"
$ docker-machine-nfs default98

exports:6: /Users conflicts with existing export /Users/sebas/Virtual/projects/myprojectwithvagrant

but still same error, maybe I'm doing something wrong :/

from docker-machine-nfs.

Hey @sebas5384 ,

I could be wrong but it could be related to the fact that one machine tries to share /Users/sebas/Virtual/... and the other /Users only. I would have to test this to confirm.

@tonivdv yep! that was the problem :(

So now I just comment the Vagrant mount whenever I want to use the docker-machine with nfs.

I can't figure it out which project should deal with this, but I feel like Vagrant isn't removing the Vagrant mount when the virtual machine is down. That could resolve this issue, ... I think.

Thanks for the help!

It's Local that should be using a more specific path, their path overlaps everything.
