Unable to use volume provided by vieux/sshfs

[chrsch]

Goal: Assign sshfs based volume to a docker container.
Note 1: sshfs is accessible as tested with other sftp client
Note 2: The problem is related to the password: If it contains specific chars e. g. } )

Step 1: Install plugin
docker plugin install vieux/sshfs

Step 2: Create volume
docker volume create -d vieux/sshfs --name sshfs -o sshcmd=user-id@sftp.somehost.com:/some/path/ -o password=xxx

Step 3: Check if volume is mounted and can be used
docker run --rm -v sshfs:/data busybox ls /data

Expected result:
List of directories and files from '/some/path/'

Received result:

docker: Error response from daemon: error while mounting volume '/mnt/sda1/var/lib/docker/plugins/49b619c1775bf25bc55b481477ea744a3a080c3f7fd66fcce28f6596c4dbe7ae/rootfs/mnt/volumes/426d940205d7b244b5baa035db7f7686': VolumeDriver.Mount: exit status 2.

@chrsch can you try with vieux/sshfs:next ? I believe @tiborvass fixed this issue already.

Thanks.

[chrsch]

@vieux Yes it is fixed the way @tiborvass modified it. Thanks.

I'm getting the error even if I use vieux/sshfs:next:

Error response from daemon: error while mounting volume '/mnt/volumes/a9308e0c6ba90e1e44c4d39ba66998a5': VolumeDriver.Mount: exit status 1%!(EXTRA []interface {}=[])

$ docker volume inspect sshvolume

[
{
"Driver": "vieux/sshfs:next",

"allow_other": "yes",
"password": "xxxx",
"sshcmd": "admin@10.87.74.162:/home/admin"
},

}
]

Commands I used:

docker volume create -d vieux/sshfs:next -o sshcmd=admin@10.87.74.162:/home/admin -o password=xxxx -o allow_other=yes sshvolume

docker run -it -v sshvolume:/app ubuntu:16.10 /bin/bash

@Abhisek- hi, I just removed the next tag, it's quite old, do you have the same error with vieux/sshfs:latest ? if so, can you please enable debug and retry ?

[paniabhisek]

@vieux hi, for vieux/sshfs:latest, yesterday I was getting the same error. but luckily today I'm getting different error :)

Commands I've executed:

docker plugin install vieux/sshfs:latest DEBUG=1
docker volume create -d vieux/sshfs -o sshcmd=admin@10.74.30.156:/pt sshvolume
docker run -it --privileged -v sshvolume:/pt --name ssh-new1 ad13c28ad7a8 /bin/bash

For the above I'm getting

C:\Program Files\Docker Toolbox\docker.exe: Error response from daemon: VolumeDriver.Mount: sshfs command execute failed: exit status 1 (read: Connection reset by peer).
See 'C:\Program Files\Docker Toolbox\docker.exe run --help'.

But If I execute without using the volume and run sshfs within container it works fine:

docker run -it --privileged --name ssh-new1 ad13c28ad7a8 /bin/bash
sshfs -o allow_other admin@10.74.30.156:/pt /pt

I've also tried

docker volume create -d vieux/sshfs -o allow_other -o sshcmd=admin@10.74.30.156:/pt sshvolume

but no luck till now

[paniabhisek]

If I do docker run -it -v sshvolume:/pt --name ssh-new ssh-new /bin/bash without --privileged, I get

C:\Program Files\Docker Toolbox\docker.exe: Error response from daemon: error while mounting volume '/mnt/sda1/var/lib/docker/plugins/646e80e39e7f1505

Any idea ?
