| The OpenStack charms will be managed under a 6 monthly release cycle aligned to Ubuntu’s. During this cycle, feature development and bug fixes will be made against ‘next’ branches, leaving the trunk branches in a stable state. Bug fixes, when appropriate, may be backported to the stable trunk branch under a similar process to the Ubuntu SRU process. | {{{ openstack-origin: distro }}} |

| Charm users will discover bugs in the OpenStack charms; Fixes for such bugs must be made in the /next branch first. After review and merging into /next, fixes may also be targeted to the stable branch with the following requirements: | Supported values for Ubuntu 12.04 LTS include: |

| * A bug report must be present for the problem, with appropriate procedure on how to reproduce the bug to support verification testing. * The branch should contain the minimal fix for the bug; branches should not included unrelated bug fixes or features. * Unit tests and amulet tests should be included to prevent regressions in the future. * Small new features may be introduced, so long as they don’t change default configuration and have limited scope for regression of the charm codebase. * New unit and amulet tests may also be added to stable branches. |

Charm Use: OpenStack Origin
The majority of OpenStack charms support the configuration option 'openstack-origin'. This option allows the charm to source various different releases of OpenStack from the Ubuntu distribution, the Ubuntu Cloud Archive and from various other sources.
Ubuntu
To use the version of OpenStack that shipped as part of an Ubuntu release, simple set:
openstack-origin: distro
This format also supports testing of charms with versions of OpenStack in the SRU process:
openstack-origin: distro-proposed
As a reference, here are the mappings between OpenStack release and Ubuntu release:
Ubuntu Release |
Ubuntu Codename |
OpenStack Release |
12.04 |
Precise |
Essex |
14.04 |
Trusty |
Icehouse |
15.04 |
Vivid |
Kilo |
15.10 |
Wily |
Liberty |
16.04 |
Xenial |
Mitaka |
NOTE: Xenial/Mitaka is still in development.
Ubuntu Cloud Archive
The Ubuntu Cloud Archive provides backports of OpenStack releases to Ubuntu 14.04 LTS and to Ubuntu 12.04 LTS.
Ubuntu 14.04
Supported values for Ubuntu 14.04 LTS include:
openstack-origin: cloud:trusty-juno openstack-origin: cloud:trusty-kilo openstack-origin: cloud:trusty-liberty
Again, proposed updates in the stable release update process may also be tested:
openstack-origin: cloud:trusty-juno/proposed openstack-origin: cloud:trusty-kilo/proposed openstack-origin: cloud:trusty-liberty/proposed
Ubuntu 12.04
Supported values for Ubuntu 12.04 LTS include:
openstack-origin: cloud:precise-icehouse
Again, proposed updates in the stable release update process may also be tested:
openstack-origin: cloud:precise-icehouse/proposed
Using PPA's
The openstack-origin option also supports use of PPA's, however the name of the PPA must include the release codename of the OpenStack release it contains, for example:
openstack-origin: ppa:james-page/liberty-testing
Using 'deb...' source entries
The openstack-origin option also supports direct entry of 'deb...' source entries, with an optional GPG key for authentication of packages, for example:
openstack-origin: "deb http://ppa.launchpad.net/james-page/liberty-testing/ubuntu trusty main|448413DC"
The above example manual configures the sources file with the equivalent of the example given for PPA's. Again the provided value must contain the release of OpenStack that the archive contains.
