Open Stack

Hi Fabrizio,


Thanks for your reply. I’ve installed OpenStack Kilo on CentOS 7 with KVM
and nova-network (alongside nova, glance, keystone, horizon). And I want to
add a Compute node with docker 1.6 hypervisor to the first node (I have
nova-compute, nova-network and nova-docker on this server).

Yep, Glance can recognize docker images.

Yesterday, I could successfully download and run tutum/wordpress with
OpenStack. But when I want to use my own docker image I receive the
following error (surely I can run it with docker run):

PS: I've overcome the previously mailed error by running docker container
with “/bin/bash” and creating a new image from it and then upload that
image to glance.

Reza
