I'm run : 

docker run --rm --name ceph-dashboard -p 15000:5000 --volumes-from deis-store-monitor-data ianblenke/ceph-dash

but, request and response:

{
    code: 400,
    message: "rados error: error calling connect: errno EINVAL"
}

and logs:

server name not found: iZ25cyxglzdZ (Name or service not known)
unable to parse addrs in 'iZ25cyxglzdZ,iZ25pw48p7cZ,iZ25upc1oz5Z'

please help me, thanks

Your server names aren't resolvable. The shortes path to fixing this for your deployment would be to add the hostnames and their IP addresses to /etc/hosts in that ceph-dash container. That could be as easy as a volume mount to /etc/hosts that you create ahead of starting that container.

Hope this helps.

Note that your container's /etc/hosts file is different than your underlying docker hosts' /etc/hosts file.

I'm betting that you added the host names to your docker host, and your docker containers have no way of resolving them.
