Ubuntu is the reference platform for OpenStack. We follow the Ubuntu release cycle very closely, and do most of our QA on Ubuntu.

If you want to run OpenStack on Ubuntu, there are a few options, depending on your stability requirements and which version of Ubuntu you're running.

Trunk PPA

A PPA<<FootNote(Personal Package Archive: an extra apt repository you can add to your sources.list to get access to software not in Ubuntu.)>> where we will upload a new version for every single commit on trunk.

Information and instructions for use can be found on Launchpad for Nova, and similarly for Swift and Glance. Swift has documented the process for building and deploying custom Debian packages at http://swift.openstack.org/debian_package_guide.html.

Release PPA

Information and instructions for use can be found on Launchpad for Nova, and similarly for Swift and Glance..

A PPA<<FootNote(Personal Package Archive: an extra apt repository you can add to your sources.list to get access to software not in Ubuntu.)>> where we will upload only final releases.

Generating packages manually

Prerequisites

You'll need to install some packages on the build machine. Some of them are in the nova-core trunk PPA, so add it as a repository:

sudo add-apt-repository ppa:nova-core/trunk
sudo apt-get update

To grab all the build dependencies of nova:

sudo apt-get build-dep nova

You'll need Sphinx 1.0 or greater for doing the build or the documentation generation will fail and the build will abort. You can check what version of Sphinx is being used by your version of Python by doing:

python -c "import sphinx; print sphinx.__version__"

Finally, you'll need the following packages on your system to be able to generate the packages:

sudo apt-get install dpkg-dev quilt debhelper

Generating binary packages

Combine the main nova code with the packaging scripts:

bzr export nova lp:nova
bzr export nova-packaging lp:~openstack-ubuntu-packagers/ubuntu/natty/nova/ubuntu
mv nova-packaging/debian nova

Edit the changelog entry. The following commands will specify a Lucid package with version "2011.1-0ubuntu2-local1" and a changelog entry "Local build for internal testing"

cd nova
dch -v 2011.1-0ubuntu2-local1 -D lucid "Local build for internal testing"

If you're building for Lucid, you need to issue the following command to apply the debian/patches/nova-manage_flagfile_location.patch patch file before building the packages.

QUILT_PATCHES=debian/patches quilt push -a

Generate the packages:

./builddeb.sh

The packages will appear in the parent of the nova directory.

Uploading custom packages to PPA

Create a PPA with the following PPA dependencies:

• nova-core/build-depends
• nova-core/release

Then issue the following commands from the root of your nova directory.

GPGKEY=... # Your registered OpenGPG key
LPNAME=... # Your Launchpad username
DIST="lucid" # The Ubuntu distribution you are targetting
VERSTRING="2011.3-my-custom-build-0ubuntu1" # Custom version string here
dch  -v "$VERSTRING" -D $DIST "Your changelog comment here"

# If building for Lucid, apply the patch manually, otherwise skip this step
QUILT_PATCHES=debian/patches quilt push -a

dpkg-buildpackage -S -sa -rfakeroot -tc -D -k$GPGKEY 
cd ..
# Upload the packages
dput ppa:${LPNAME}/ppa nova_${VERSTRING}_source.changes
