docker sshfs plugin issue

Posted on September 22, 2019

Hello. I have 2 servers, running on Centos 7.7 and docker 19.03 CE. I tried to use sshfs volumes, but something goes wrong.
I successfully creates volume with this command:[lanadmin@mordred ~]$ docker volume create --driver vieux/sshfs -o sshcmd=lanadmin@10.220.127.247:/home/test -o password=mypass sshvolume

But when i tries to use this volume in container i have an error like this:

[lanadmin@mordred ~]$ docker run -it -v sshvolume:/etc busybox ls /etc
docker: Error response from daemon: failed to copy file info for /var/lib/docker/plugins/518a1874166cf493dd0700d9efec1c3e2d7649cb4a560d44a2af1a6aa16f0526/propagated-mount/5cd59d97ef5e801349f7c06a8f2c113d: failed to chown /var/lib/docker/plugins/518a1874166cf493dd0700d9efec1c3e2d7649cb4a560d44a2af1a6aa16f0526/propagated-mount/5cd59d97ef5e801349f7c06a8f2c113d: lchown /var/lib/docker/plugins/518a1874166cf493dd0700d9efec1c3e2d7649cb4a560d44a2af1a6aa16f0526/propagated-mount/5cd59d97ef5e801349f7c06a8f2c113d: permission denied. See 'docker run --help'.

Also if i tries to use empty directory everything work fine.

And the most funny thing is when i put some file in /home/test there is no error with coping files when container runs and i have this files in /home/test:

lanadmin@ganimed ~]$ ls -lah /home/test/ 
итого 8,0K 
drwxrwxrwx. 2 lanadmin lanadmin 4,0K сен 21 23:15 . 
drwxr-xr-x. 5 root root 4,0K сен 21 18:48 .. 
-rwxr-xr-x. 1 lanadmin lanadmin 0 сен 21 23:15 hostname 
-rwxr-xr-x. 1 lanadmin lanadmin 0 сен 21 23:15 hosts 
-rw-rw-r--. 1 lanadmin lanadmin 0 сен 21 23:14 notest.file 
-rwxr-xr-x. 1 lanadmin lanadmin 0 сен 21 23:15 resolv.conf

Can anyone help me with that?

Hello,

It looks like a permissions issue, have you tried mounting a different folder besides /etc like /tmp for example?

I’ve tried recreating the setup at my end and it worked as expected with when using root:

[root@docker-test ~]# docker run -it -v sshvolume_test2:/etc busybox ls /etc
group        hosts        mtab         passwd       shadow
hostname     localtime    network      resolv.conf
[root@docker-question ~]#

Regards, Bobby
