OpenStack All in One
With this guide, you'll be able to deploy an OpenStack Juno with last OSS version of MidoNet and test it in a single Virtual Machine.
This tutorial is tested against Ubuntu 14.04, but it should work for CentOS 7 too.
If you experience the annoying unable to resolve host '<your-hostname>' , execute the following:
sed -i "1c\127.0.0.1 $(hostname) localhost" /etc/hosts
Install puppet in your machine and the midonet puppet modules:
(run as root)
apt-get -y update
apt-get install -y puppet
puppet module install midonet-midonet_openstack
puppet module install --force midonet-neutron
We need to force-install neutron, because we have our own fork for Juno releases and a neutron module will be already installed after the installation of midonet-midonet_openstack because of puppetlabs-openstack dependency. This step won't be needed since Kilo.
Create a macvlan l2 device an associate an IP address to it. This trick will allow you to copy-paste the configuration files of this tutorial without the need of modify the IP addresses and networks to your Virtual Machine network stack to the hiera.yaml configuration file. It just works.
ip l add osservices link eth0 type macvlan
ip a add 172.28.28.4/24 dev osservices
Configure hiera. Hiera should load the module_data module to leverage all the configuration options already stored in puppet-midonet/data files. So you only have to define the ones you want to override. Hiera common.yaml will live in /var/lib/hiera
cat <<EOF > /etc/puppet/hiera.yaml

Make sure /var/lib/hiera exists:

- openstack::network::api: api network is the one from which an OpenStack client access to OpenStack APIs
- openstack::network::external: is the range of the public external OpenStack network. With MidoNet lives purely in the overlay. That means that you can put any value here, while you are coherent with the values of openstack::network::external::*
- openstack::network::management: is the network from which OS services communicate each other. In this all-in-one or in trivial deployments use to be the same network as openstack::network::api
- openstack::network::data: is the underlay network that gives access from OS compute nodes to Internet. OS private networks (and MidoNet's external one) are tunneled upon this network. In this example, we use the same one as openstack::network::external, because we don't use it at all (single machine, no need of tunnel zones)
- openstack::network::neutron::private: Is the default-created tenant network. Can be any value.
Create the site.pp file:
cat <<EOF > /etc/puppet/manifests/site.pp
# Most images does not have the fqdn infored via 'facter'. This line
# tricks the deployment using fqdn as the same value as hostname
if empty(\$::fqdn) {
\$fqdn = \$::hostname
}
include midonet_openstack::role::allinone
EOF
Run the site.pp file:
$ puppet apply --verbose /etc/puppet/manifests/site.pp
By default, Horizon only will allow users from '172.28.28.4' access to it. We have to patch apache configuration files to be accessible from anywhere
$ sed -i "/^ALLOWED_HOSTS/c\ALLOWED_HOSTS = ['*']" /etc/openstack-dashboard/local_settings.py
$ sed -i "/ServerAlias 172.28.28.4/a\ \ ServerAlias *" /etc/apache2/sites-available/15-horizon_vhost.conf
$ hostnamectl set-hostname $(facter hostname)
And restart apache
$ service apache2 restart
Nova VNC is listening on port 6080 of 172.28.28.4, in order to make VNC reachable from outside we need to add a prerouting rule:
$ iptables -t nat -I PREROUTING -p tcp --dport 6080 -d {host_IP} -j DNAT --to 172.28.28.4
There is a bug in Horizon that don't let tenants see ports attached to a Virtual Machines when they are trying to associate them to a Floating IP. Create the following patch file to fix this bug.

If you restart the Virtual Machine, virtual macvlan device osservices, from where all the OpenStack services are attachedd, will not exist (we created manually). Define this upstart script to let your Virtual Machine create this machine every time the machine spawns:
cat <<EOF > /etc/init/adapt.conf

NOT READY!!!
This way you'll be able to run last version of puppet modules in GitHub instead of Puppet Forge
First clone midonet_openstack and move to the examples/allinone directory:
$ git clone git://github.com/midonet/puppet-midonet_openstack
$ cd puppet-midonet_openstack/examples/allinone
There is a Vagrantfile which defines the deployment.
Just run:
$ vagrant up
Choose the bridged interface and wait until the deployment finishes. The default user/password is midogod/midogod.
Go to the IP address of the bridged interface in your navigator to access through Horizon.
