Juno host or Controller, but just as demonstration. Might be I did something wrong , might be due to some other reason but kernel version 3.10.0-123.20.1.el7.x86_64 seems to be the first brings success on RDO Juno Compute nodes.
Follow http://lxer.com/module/newswire/view/209851/index.html up to section
"Set up Nova-Docker on Controller&&Network Node"
***************************************************
Set up Nova-Docker Driver on Compute Node
***************************************************
# yum install python-pbr
# yum install docker-io -y# git clone https://github.com/stackforge/nova-docker# cd nova-docker
# git checkout stable/juno
# python setup.py install
# systemctl start docker
# systemctl enable docker
# chmod 660 /var/run/docker.sock
# mkdir /etc/nova/rootwrap.d************************************************
Create the docker.filters file:
************************************************
vi /etc/nova/rootwrap.d/docker.filters
Insert Lines
# nova-rootwrap command filters for setting up network in the docker driver
# This file should be owned by (and only-writeable by) the root user
[Filters]
# nova/virt/docker/driver.py: 'ln', '-sf', '/var/run/netns/.*'
ln: CommandFilter, /bin/ln, root
*****************************************
Add line /etc/glance/glance-api.conf
*****************************************
container_formats=ami,ari,aki,bare,ovf,ova,docker
:wq
******************************
Update nova.conf
******************************
vi /etc/nova/nova.conf
set "compute_driver = novadocker.virt.docker.DockerDriver"
************************
Restart Services
************************
usermod -G docker nova
systemctl restart openstack-nova-compute (on Compute)
systemctl status openstack-nova-compute
systemctl restart openstack-glance-api (on Controller&&Network )
At this point `scp /root/keystonerc_admin compute:/root` from Controller to
Compute Node
*********************************************************************************
Test installation Nova-Docker Driver on Compute Node (RDO Juno , CentOS 7,
kernel 3.10.0-123.20.1.el7.x86_64 )
**********************************************************************************
*******************************************
Setup Ubuntu 14.04 with SSH access
*******************************************
First on Compute node
# docker pull rastasheep/ubuntu-sshd:14.04
# . keystonerc_admin
# docker save rastasheep/ubuntu-sshd:14.04 | glance image-create
--is-public=True --container-format=docker --disk-format=raw --name
rastasheep/ubuntu-sshd:14.04Second on Controller node launch Nova-Docker container , running on Compute, via dashboard and assign floating IP address
Verify `docker ps ` on Compute Node

Reading package lists... Done
If network operations like `apt-get install ... ` run afterwards with no problems
Nova-Docker driver is installed and works on Compute Node
**************************************************************************************
Finally I've set up openstack-nova-compute on Controller , to run several instances with Qemu/Libvirt driver :-
