Setup the most recent Nova Docker Driver via Devstack on Fedora 21

*********************************************************************************
UPDATE as 03/26/2015
To make devstack configuration persistent between reboots on Fedora 21, e.g. restart-able via ./rejoin-stack.sh, following services must be enabled :-
*********************************************************************************
systemctl enable rabbitmq-server
systemctl enable openvswitch
systemctl enable httpd
systemctl enable mariadb
systemctl enable mysqld

File /etc/rc.d/rc.local should contain ( in my case ) :-

ip addr flush dev br-ex ;
ip addr add 192.168.10.15/24 dev br-ex ;
ip link set br-ex up ;
route add -net 10.254.1.0/24 gw 192.168.10.15 ;

System is supposed to be shutdown via :-
$sudo ./unstack.sh
********************************************************************************

This post follows up http://blog.oddbit.com/2015/02/06/installing-nova-docker-on-fedora-21/  however , RDO Juno is not pre-installed and Nova Docker driver is built first based on the top commit of https://git.openstack.org/cgit/stackforge/nova-docker/ , next step is :-

$ git clone https://git.openstack.org/openstack-dev/devstack
$ cd devstack

Creating local.conf under devstack following any of two links provided
and run ./stack.sh performing AIO Openstack installation, like it does
it on Ubuntu 14.04. All steps preventing stack.sh from crash on F21 described right bellow.

# yum -y install git docker-io fedora-repos-rawhide
# yum –enablerepo=rawhide install python-six  python-pip python-pbr systemd
# reboot
# yum – y install gcc python-devel ( required for driver build )

$ git clone http://github.com/stackforge/nova-docker.git
$ cd nova-docker
$ sudo pip install .

To raise to 1.9 version python-six dropped to 1.2 during driver’s build

yum –enablerepo=rawhide reinstall python-six

Run devstack with Lars’s local.conf
per http://blog.oddbit.com/2015/02/11/installing-novadocker-with-devstack/
or view  http://bderzhavets.blogspot.com/2015/02/set-up-nova-docker-driver-on-ubuntu.html   for another version of local.conf

**************************************************************************************
After stack.sh completion disable firewalld, because devstack has no interaction with fedoras firewalld bringing up openstack daemons requiring corresponding ports  to be opened.
***************************************************************************************

#  systemctl stop firewalld
#  systemtcl disable firewalld

$ cd dev*
$ . openrc demo
$ neutron security-group-rule-create –protocol icmp \
–direction ingress –remote-ip-prefix 0.0.0.0/0 default
$ neutron security-group-rule-create –protocol tcp \
–port-range-min 22 –port-range-max 22 \
–direction ingress –remote-ip-prefix 0.0.0.0/0 default
$ neutron security-group-rule-create –protocol tcp \
–port-range-min 80 –port-range-max 80 \
–direction ingress –remote-ip-prefix 0.0.0.0/0 default

Uploading docker image to glance

$ . openrc admin
$  docker pull rastasheep/ubuntu-sshd:14.04
$  docker save rastasheep/ubuntu-sshd:14.04 | glance image-create –is-public=True   –container-format=docker –disk-format=raw –name rastasheep/ubuntu-sshd:14.04

Launch new instance via uploaded image :-

$ . openrc demo
$  nova boot –image “rastasheep/ubuntu-sshd:14.04” –flavor m1.tiny
–nic net-id=private-net-id UbuntuDocker

To provide internet access for launched nova-docker instance run :-
# iptables -t nat -A POSTROUTING -o eth0 -j MASQUERADE
Horizon is unavailable , regardless installed
