Late Friday night July 3rd 2015, or early evening to my US counterparts, we finished the edits on the OpenStack Cloud Computing Cookbook, 3rd Edition. Wow – 3 Editions.
I started writing the first edition back in 2011. Back then, OpenStack Diablo was THE production ready release. It had many promises and I was keen to learn more after dipping my toes into the OpenStack water with the Bexar release months before. Of course, I pronounced this wrong. So much for a country who frowns upon our additional characters in the English language.
This book was very popular and has taken me on a journey I wasn’t expecting. As time went on, Diablo wasn’t as hot property as it sounds and after being approached by none other than Cody Bunch who convinced me to write another, the 2nd Edition was needed. This was another 10 months getting a “few updates” in the book. This was published in June 2013 and was based on Grizzly.
Fast forward towards the end of 2014 and through a mental lapse, Cody yet again thought it might be a good idea to do another. Along the way of ideas, we picked up the esteemed Egle Sigler. Putting in a few more updates and with 50% more help, this would be a breeze to get the book updated for Juno. Or so we thought.
About 8 months later, we made it. We have updated sections that include how to install the very latest OpenStack Kilo using Ansible. Over 110 recipes has had an upgrade, rewrite or is a brand new addition to the book. We listened and we have a book that takes you through all the essential components and much more. We take you through step by step instructions on how you could run this in your datacentres.
We wouldn’t have made this possible without the immense valuable feedback from our tech reviewers. Thank you for keeping us on track and making this book even better than it was going to be:
And a big shout out to Tim Bell for writing an excellent foreword to the book. We are truly honoured. I’m expecting a signed copy from him in the post.
So go out and by the thing. You won’t regret it.
Ubuntu 14.04 LTS, the release used throughout this book, provides two repositories for installing OpenStack. The standard repository ships with the Icehouse release of OpenStack. Whereas a further supported repository, called the Ubuntu Cloud Archive, provides access to the latest release (at time of writing), Juno. We will be performing an installation and configuration of OpenStack Identity service (as well as the rest of the OpenStack services) with packages from the Ubuntu Cloud Archive to provide us with the Juno release of software.
Ensure you have a suitable server available for installation of the OpenStack Identity service components. If you are using the accompanying Vagrant environment as described in the Preface this will be the controller node that we will be using.
Ensure you are logged onto the controller node and that it has Internet access to allow us to install the required packages in our environment for running Keystone. If you created this node with Vagrant, you can execute the following command:
vagrant ssh controller
How to do it…
Carry out the following steps to configure Ubuntu 14.04 LTS to use the Ubuntu Cloud Archive:
- To access the Ubuntu Cloud Archive repository, we first install the Ubuntu Cloud Archive Keyring and enable Personal Package Archives within Ubuntu as follows:
sudo apt-get update sudo apt-get install -y software-properties-common ubuntu-cloud-keyring
- Next we enable the Ubuntu Cloud Archive for OpenStack Juno. We do this as follows:
sudo add-apt-repository -y cloud-archive:juno sudo apt-get update
How it works…
What we’re doing here is adding an extra repository to our system that provides us with a tested set of packages of OpenStack that is fully supported on Ubuntu 14.04 LTS release. The packages in here will then be ones that will be used when we perform installation of OpenStack on our system.
More information about the Ubuntu Cloud Archive can be found by visiting the following address: https://wiki.ubuntu.com/ServerTeam/CloudArchive. This explains the release process and the ability to use latest releases of OpenStack—where new versions are released every 6 months—on a long term supported release of Ubuntu that gets released every 2 years.
Using an alternative release
If you wish to optionally deviate from stable releases, it is appropriate when you are helping to develop or debug OpenStack, or require functionality that is not available in the current release.
To use a particular release of PPA, for example, the next OpenStack release Kilo, we issue the following command:
sudo add-apt-repository cloud-archive:kilo
