Openstack kilo playing nicely with docker

This has been tested on Centos 7, Ubuntu should be absolutely same thing. Start up virtual machine, I am running Centos 7 (6 cores + 8Gigs of RAM assinged) through parallels on mac, smaller VM will work too.
To make things simpler, I will disable selinux on Centos 7 and make Dan Walsh cry, so either run setenforce 0, or edit /etc/sysconfig/selinux (set to disabled and reboot).

#Update system before we start
sudo yum install epel-release
sudo yum -y update
sudo yum -y install python-pip python-devel git openssh-server
sudo yum groupinstall "Development Tools"
sudo setenforce 0
sudo mkdir /opt/stack && chown deki:deki /opt/stack/ -R
git clone https://git.openstack.org/stackforge/nova-docker /opt/stack/nova-docker
git clone https://git.openstack.org/openstack-dev/devstack /opt/stack/devstack
#Switch to kilo stable branch
cd /opt/stack/nova-docker && git checkout -b kilo origin/stable/kilo
cd /opt/stack/devstack && git checkout -b kilo origin/stable/kilo
cd /opt/stack/nova-docker
./contrib/devstack/prepare_devstack.sh

Now the important bit, as stack.sh will not work without it:
Edit file: /opt/stack/nova-docker/novadocker/virt/docker/driver.py
Change:
from nova.openstack.common import fileutils to from oslo_utils import fileutils
To simplify further, I will not make any other modifications to devstack, so

cd /opt/stack/devstack 
#Run stack.sh and have a cup of coffee
./stack.sh

It should complete and show something like:

##This is your host IP address: 10.211.55.34
##2015-08-05 09:40:07.103 | Skip setting lvm filters for non Ubuntu systems
##This is your host IPv6 address: ::1
##Horizon is now available at http://10.211.55.34/
##Keystone is serving at http://10.211.55.34:5000/
##The default users are: admin and demo
##The password: mysecretpassword
##2015-08-05 09:40:07.108 | stack.sh completed in 278 seconds.

In my case I had to restart firewall, not sure yet why, so do:

sudo service firewalld status
#
#If it shows:
#Loaded: loaded (/usr/lib/systemd/system/firewalld.service; disabled)
#   Active: inactive (dead)
#run:
sudo service firewalld start

So lets verify all is well:

docker version
# Lets try it out:
. openrc admin
docker pull larsks/thttpd
docker save larsks/thttpd | glance image-create \
--name larsks/thttpd \
--is-public true \
--container-format docker \
--disk-format raw

. openrc demo
nova boot --image larsks/thttpd \
--flavor m1.small test0

#Wait a bit and nova list will show:
[deki@localhost devstack]$ nova list
+--------------------------------------+-------+--------+------------+-------------+------------------+
| ID                                   | Name  | Status | Task State | Power State | Networks         |

+--------------------------------------+-------+--------+------------+-------------+------------------+

#then:
[deki@localhost devstack]$ nova floating-ip-create

+----+------------+-----------+----------+--------+

nova floating-ip-associate test0 172.24.4.1
#and finally try it out and behold:
curl http://172.24.4.1
#will return bellow:

You have a web server.

  
  

    
This is a statically compiled version of thttpd 
    put together to build a demonstration container for my
    Heat templates for Kubernetes.  But maybe 
    you'll find it useful for other things.
