nfs share / guest to host

[aheissenberger]

I have allready added nfs-utilities to the ISO but have some troubles to forward the nfs ports to osx.

/etc/sysconfig/nfs:
RQUOTAD_PORT=875
LOCKD_TCPPORT=32803
LOCKD_UDPPORT=32769
MOUNTD_PORT=892
STATD_PORT=662

this plus 111 TCP/UDP, 2049 TCP/UDP are forwarded by virtual box to local host.

I have no problem to mount the share local inside the vm but mounting the share from OSX gives me:

sudo mount -o resvport,vers=3 127.0.0.1:'/var/lib/docker/share' '/Users/ah/tmp/mnt'
mount_nfs: can't mount /var/lib/docker/share from 127.0.0.1 onto /Users/ah/tmp/mnt: No such file or directory

Did you consider using the 9p filesystem?
It just requires a TCP connection (no portmapper etc.) and is dead simple to setup on the server side.
See https://gist.github.com/jpetazzo/5668338 for an example (that has to be adapted of course, since the example involves containers).

I have not found a 9p Server/Client for OSX

Argh, I thought that diod might be available for OSX.
It should be straightforward to compile, but I never tried that (I don't
use OSX). :-(

I have go it working:

1. I am using a host only network on eth1
2. exporting a share from OSX does work
3. exporting a share from docker vm works

open problems:

1. exporting a share from OS only works if security is set to no - which I only can set with "NFS Manager" - not able to get this configuration in my /etc/exports config:
   /Users/ah/SVN-Checkouts/DEV/dev -network 192.168.56.0 -mask 255.255.255.0

You can find a working new boot2docker which adds the hostonly adaper and the ISO which include the nfs utilities here:
https://github.com/aheissenberger/boot2docker

do not forget to start the nfs client or server inside the VM:
sudo /usr/local/etc/init.d/nfs-server start
sudo /usr/local/etc/init.d/nfs-client start

Here is the patch to use it - but the code is not finally cleaned up and you need to rebuid the ISO:

Here is the link to the bug preventing tiny core to support NAT and hostonly in a VM:
https://bugs.busybox.net/show_bug.cgi?id=6788

my code above contains the fix already

Thanks a ton for your efforts @aheissenberger !

[aheissenberger]

@schickling the existing code in in my repository creates an ISO with nfs support but at the moment you have to manuel mount the shares.

@steeve would be nice if the docker remote client could tell the daemon to handle the mounting if the hostpath contains an IP - e.g:
docker run -v 192.168.56.1:/var/logs:/var/host_logs:ro ubuntu bash

[schickling]

@aheissenberger Will you open a PR with your NFS settings?

I made diod work in OSX, see #89, and https://github.com/kainz/diod.
