Deploying a multi node setup of OpenStack Folsom on Ubuntu 12.04.1 LTS with one command
2012-12-01 14:45:13 +0000
We’re going to cook some OpenStack today, so get your ingredients ready:
- vagrant
- git
- A Hosted Chef Account (You can use your own chef server, of course. Installing a chef server e.g. via knife-server is out of scope of this tutorial, though)
- librarian-chef -
gem install librarian
- spiceweasel -
gem install spiceweasel
To be honest, if you count the environment set up commands it’s not one command but about five for the whole process. But after the environment set up you can repeat the process using the one setup command over and over again. This is pretty useful for environment specific testing, CI, etc.
Instead of using vagrant with VirtualBox you can of course use your favourite virtualisation solution for testing or use a bare metal setup. All you need is at least two running machines with Ubuntu 12.04 on them. Instead of
vagrant up
you would then useknife bootstrap
with thesingle-controller
andsingle-compute role
.
So let’s cook:
Checkout the Chef cookbooks and Vagrantfile
git clone https://www.github.com/cloudbau/openstack-chef-repo.git
librarian-chef update
Set up Chef server environment
Using hosted chef is the easiest way to get started, but you can of course use your own Chef server. The Vagrantfile uses 2GB per node at the moment. So be careful not to exceed your RAM if you increase the compute node count.
vi config.rb # Change the Chef server settings
Upload cookbooks to chef server
spiceweasel infrastructure.yml | sh
Deploy
Now deploy Openstack!
vagrant up
Get a coffee, tea or whatever you like while it’s cooking…
Use it
Open a browser window at http://10.0.112.10
to log in to your OpenStack dashboard. The default username and password is “admin” and “secrete”. If you want to change that, have a look at the attributes of the keystone cookbook.
What’s next
The community chef cookbooks are still under development and the version used here is a slightly modified so that it works with OpenStack Folsom. These changes will be merged back (pull requests are pending) to the community cookbooks and the cookbooks will certainly evolve and also cover OpenStack services like cinder and quantum.
