Configuring Ubuntu Cloud Archive for OpenStack

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.

Getting ready

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:

  1. 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
  2. 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.

There’s more…

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
