For those of us that need to share files with a windows host.

Agreed. The kernel module is in the OS, but not the mount tool. Very helpful for vagrant users on windows

After a bit of research in order to get mount.cifs, we'll need to add cifs-utils, to add cifs-utils, we'll need all of Samba (I think you can see where this is going). Unfortunately (at this time, never say never) we aren't ready to give that mouse that cookie.

Are you sure about that? Seems to run ok for me with zero deps:

Build cifs-utils in a container and copy it into /tmp on the host.

$ docker run -t -i -v /tmp:/host_tmp fedora /bin/bash

# yum groupinstall -y "Development Tools" "Development Libraries"
# yum install -y bzip2
# curl http://ftp.samba.org/pub/linux-cifs/cifs-utils/cifs-utils-6.3.tar.bz2 | bunzip2 -c - | tar -xvf -
# cd cifs-utils-6.3/
# ./configure && make
# cp mount.cifs /host_tmp/
# exit

Works fine!

$ sudo mkdir /mnt/foo
$ sudo /tmp/mount.cifs //198.51.100.23/foo /mnt/foo -oguest
$ mount | grep /mnt/foo

//198.51.100.23/foo on /mnt/foo type cifs (rw,relatime,vers=1.0,cache=strict,domain=TEST,uid=0,noforceuid,gid=0,noforcegid,addr=198.51.100.23,unix,posixpaths,serverino,acl,rsize=1048576,wsize=65536,actimeo=1)

lib requirements

$ ldd /tmp/mount.cifs 
    linux-vdso.so.1 (0x00007fffe09fe000)
    libcap.so.2 => /lib64/libcap.so.2 (0x00007fb55c5ec000)
    libc.so.6 => /lib64/libc.so.6 (0x00007fb55c23f000)
    libattr.so.1 => /lib64/libattr.so.1 (0x00007fb55c039000)
    /lib64/ld-linux-x86-64.so.2 (0x00007fb55c7f2000)

If you still don't want to include it because of bloat (totally understandable), at least there's a recipe for folks who want to build it themselves :)

Currently Azure with its "Azure File Service" only supports SMB with CIFS so in order to get a shared mount with CoreOS this will be needed.

Exactly, cifs-utils >= 6.0 is required to connect using SMB version 2.1. Managed the mount to "Azure File Service" this week using Ubuntu 14.04.1 that ships with a recent version. Found this issue while my investigation if CoreOS provides this requirement.

So I've got the mount.cifs file created and it works manually. As far as I'm aware, I cannot use a units file to mount the CIFS share ala http://blog.scottlowe.org/2015/02/20/config-mount-nfs-coreos/, as I don't have the mount.cifs binary in /sbin, right?

Can I use a service file to auto mount at boot? Any other recommendations?

@carpenike: Yes, you should probably use a one-shot service which fetches (if not present) and runs mount.cifs. At least that's what I am doing. (Consider running a docker container for getting the binary, as explained above).

To start on boot, you need to setAfter=network.target in the Unit section and WantedBy=multi-user.target in the Install section.

If the mount is needed by one or more particular services, you might as well do the mount on demand. Just add a Requires and an After with the mount service in the depending service(s).

Do you have a service file already? I tried getting one working earlier and will post it when I get home if you don't.

@carpenike: You can run a docker image in ExecStartPre to get you the mount.cifs binary. I found this one. The following copies the binary to /opt/bin:

ExecStartPre=/usr/bin/docker run -v /opt/bin:/target sigma/mount.cifs-copy /target

sepiroth887 · 2015-11-24T18:21:33Z

btw, the binary from ubuntu:14.04 cifs-utils (mount.cifs) is compatible with coreOS. I started out using the mount.cifs_copy image but later just tried it and it works just fine.

Using it for really simple use cases so not sure whether all features have the required libraries.
Tested on 766.(3-5).0

If you want to use Azure with CoreOS, this is probably a requirement.

phagunbaya · 2016-05-09T11:27:45Z

bobintornado · 2016-05-12T09:18:56Z

+1

Since the kernel is already supporting CIFS since release 899.1.0 (also CEPH, NFS and 9P), I think it make senses to add in the support from the tooling side.

Plus it's a must to have to run a CoreOS Kubernete cluster on Azure.

edevil · 2016-06-19T19:50:24Z

I'm also interested in mounting Azure shares on my CoreOS kubernetes nodes.

monaka · 2016-07-11T04:06:45Z

Off topic: @edevil I found an hacky workaround against this issue and tried to run K8s nodes. But there have the another issue. You must apply a patch to K8s if you want to use Azure File.

monaka · 2016-07-11T05:43:27Z

I put the workaround on https://gist.github.com/monaka/5cb1f33e5317e29285843f158a387c9b .
This will enable to execute "mount -tcifs" (So you're close to azureFile volumes on K8s).
Hope some helps.

jcrowthe · 2017-03-31T23:19:44Z

@monaka Any update to this issue? I am exploring using Azure File storage with CoreOS, which still requires SMB support.

monaka · 2017-04-01T01:19:29Z

@jcrowthe The issue was fixed if you want to use CIFS on K8s (Hyperkube).
See kubernetes/kubernetes@3aaf0a8

And the workaround I posted above will work (probably).

veeresh1982 · 2017-10-16T23:00:34Z

Is they any plan/ETA to get mount.cifs installed on coreos ?

rasmus · 2017-12-28T18:40:09Z

Would really like to get get an ETA/no-go on this one? A "priority/P1" from two years ago doesn't really bode well.

dtretyakov · 2018-01-25T10:36:33Z

@crawford, it's really valuable when using CoreOS in Azure to be able to mount Azure File Shares to the host.

What problem prevents adding cifs-utils into CoreOS distributions?

r7vme · 2018-07-18T17:34:12Z

Good evening.

Just adding huge +1 to have mount.cifs in CoreOS.

I think this now affects many people that run CoreOS + Kubernetes on Azure and will be using Azure File backend.

Workarounds with putting mount.cifs into /opt/bin does not work, becuase Kubernetes uses mount -t cifs. By default mount will look only in /sbin for helpers. In CoreOS /sbin is read-only, which makes impossible to make mount -t cifs work.

To test that this is the case, i did following hack:

mkdir /sbin2
cp -a /sbin/* /sbin2
# remove symlink
rm -r /sbin
mv /sbin2 /sbin
# Copy mount.cifs binary from kubelet container
docker cp k8s-kubelet.service:/sbin/mount.cifs /sbin
