How to install Contrail on a single node Ubuntu system.

I wanted to install and test out a contrail set on a single node system.

I first started with a clean Ubuntu server. Contrail seems to have support on 12.04LTS version of code (12.04.03 to be precise). So I downloaded the amd64-iso file and did a fresh install on a system.

After it came up I did some package adds to get the machine prepped.

First I made sure I was root.
sudo su
I gave root a password. This is to be used later when Contrail tries to install packages using root.

This are the files I noticed while looking at different blogs on the website. I'm not sure if all these dependencies are needed. This is what worked for me. (I'm pretty sure git isn't needed here, but I use git for other projects so I did it anyways.)

apt-get install  -y git-core ant build-essential pkg-config linux-headers-3.2.0-35-virtual
apt-get install -y scons git python-lxml wget gcc patch make unzip flex bison g++ libssl-dev autoconf automake libtool pkg-config vim python-dev python-setuptools python-paramiko

apt-get update

Then I went onto the Juniper website and downloaded the software.

You DON'T have to install Openstack first to get this going.

This package has Contrail plus the Openstack Havana version built in.

I ftp or scp this file onto my ubuntu server.

I place it in the /tmp directory.

Next I install the package.

dpkg -i contrail-install-packages_1.05.1-234~havana_all.deb

The packages get placed in a contrail directory.

cd /opt/contrail/contrail_packages

Then I run the setup shell script.


After this, you'll need to create or modify a script. This tells contrail how install the compute, storage and control nodes. Since this is an all-in-one system, I going to clone the single box example and modify it.

cd /opt/contrail/utils/fabfile/testbeds/


Next I edit the file.


In order to execute this file, you need to back up a few directories (I know it's lame, the command doesn't seem to execute in the correct directory.)

cd /opt/contrail/utils

Next you will issue the fabric command

fab install_contrail

fab setup_all

After a few minutes, the scripts will run and more packages will be installed and configured to the specifications of your testbed file.

The server will reboot automatically.

After it comes back up sudo su when you login again

Then you need to source your authentication files.

keystonerc  and openstackrc  are located in /etc/contrail

source /etc/contrail/keystonerc
source /etc/contrail/openstackrc

Here are some commands  you can issue after installation to check the state of openstack

You are now ready to login to the Horizon Dashboard to configure your Openstack platform.


To log into your contrail controller change the port number to 8143


Next time I'll show how create a MP-BGP connection to a MX gateway to all traffic from the virtual network to connect to a physical network.
