Releases
========
The `project creator's guide
<https://docs.openstack.org/infra/manual/drivers.html#release-management>`__
provides information on release management. As Kayobe is not an official
project, it cannot use the official release tooling in the
``openstack/releases`` repository.
There are various `useful files
<http://git.openstack.org/cgit/openstack-infra/project-config/tree/roles/copy-release-tools-scripts/files/release-tools/>`__
in the ``openstack-infra/project-config`` repository. In particular, see the
``releases.sh`` and ``make_branch.sh`` scripts.
Preparing for a release
=======================
Synchronise kayobe-config
-------------------------
Ensure that configuration defaults in ``kayobe-config`` are in sync with those
under ``etc/kayobe`` in ``kayobe``. This can be done via:
.. code-block:: console
cp -aR kayobe/etc/kayobe/* kayobe-config/etc/kayobe
Commit the changes and submit for review.
Synchronise kayobe-config-dev
-----------------------------
Ensure that configuration defaults in ``kayobe-config-dev`` are in sync with
those in ``kayobe-config``. This requires a little more care, since some
configuration options have been changed from the defaults. Choose a method to
suit you and be careful not to lose any configuration.
Commit the changes and submit for review.
Add a prelude to release notes
------------------------------
It's possible to add a prelude to the release notes for a particular release
using a ``prelude`` section in a ``reno`` note.
Creating a stable branch
========================
Stable branches should be cut for each Kayobe deliverable (``kayobe``,
``kayobe-config``, ``kayobe-config-dev``).
To create a branch ``<new branch>`` at commit ``<ref>``:
.. code-block:: console
cd /path/to/repo
git checkout -b <new branch> <ref>
git review -s
git push gerrit <new branch>
After creating the branch, on the new branch:
* update the ``.gitreview`` file on the new branch, for example:
https://review.openstack.org/609735
* update the references to upper-constraints to use the stable branch,
For example https://review.openstack.org/#/c/568804.
For the kayobe repo only, on the master branch:
* update the release notes for the new release series:
https://review.openstack.org/609742
Creating a release
==================
Prerequisites
-------------
Creating a signed tagged release requires a GPG key to be used. There are
various resources for how to set this up, including
https://help.ubuntu.com/community/GnuPrivacyGuardHowto. Your default Gerrit
email should be added to the key, and the key should be trusted ultimately, see
https://wiki.openstack.org/wiki/Oslo/ReleaseProcess#Setting_Up_GPG for
information.
Tagging a release
-----------------
Tags should be created for each deliverable (``kayobe``, ``kayobe-config``,
``kayobe-config-dev``). Currently the same version is used for each.
The ``tools/release.sh`` script in the ``kayobe`` repository can be used to tag
a release and push it to Gerrit. For example, to tag and release the ``kayobe``
deliverable version ``4.0.0`` in the Queens series from the tip of the
``stable/queens`` branch:
.. code-block:: console
./tools/release.sh kayobe 4.0.0 origin/stable/queens queens
Post-release activites
----------------------
An email will be sent to the release-announce mailing list about the new
release.
.. TODO: Setup RTD integration for release notes.
The release notes need to be rebuilt manually since there is no readthedocs
webhook integration for these yet.
