Description Qian Cai 2016-04-14 18:09:57 UTC 
Description of problem:
# /usr/lib/docker-latest/docker-latest-novolume-plugin
# ls /var/run/docker/plugins/
docker-novolume-plugin.sock

It would be better to created a socket called docker-latest-novolume-plugin.sock instead for consistent to match the value passed into /etc/sysconfig/docker-latest conf file. If they don't match, it will error out,

#  docker-latest run -v /:/test fedora sh
docker: Error response from daemon: plugin docker-latest-novolume-plugin failed with error: plugin not found.

Version-Release number of selected component (if applicable):
docker-latest-novolume-plugin-1.10.3-9.el7.x86_64

How reproducible:
always

fixed in upcoming ...
Comment 4 Qian Cai 2016-04-19 18:09:35 UTC 
Still error out,

# docker-latest info
Error response from daemon: plugin docker-latest-novolume-plugin failed with error: plugin not found

The socket file was created under,
/run/docker-latest/plugins/docker-latest-novolume-plugin.sock

However, docker-latest daemon still look for one under,
/run/docker/

A workaround is,

# ln -s /run/docker-latest/plugins /run/docker/plugins
# docker-latest info
<Working fine.>

Sigh, the plugin directory seems hard-coded to /run/docker since passed -exec-root /run/docker-latest does not help.
Comment 5 Daniel Walsh 2016-05-04 17:34:58 UTC 
This package should not exist. There should be no plugins that are called docker-latest.  docker-latest should only change docker code and the docker-storage-setup.
Comment 6 Antonio Murdaca 2016-05-04 17:37:58 UTC 
I have an idea why the socket is created in the wrong directory though. Will look more into it later today.

Plugin subpackages only have docker- prefixed now.
Comment 8 Daniel Walsh 2016-05-04 20:25:30 UTC 
Lets close this as fix now.
Comment 9 Luwen Su 2016-05-05 03:20:02 UTC 
Fine to me in docker-latest-1.10.3-22.el7.x86_64
