stackrc DevStack settings
-------------------------
``stackrc`` is the primary configuration file for DevStack. It contains
all of the settings that control the services started and the
repositories used to download the source for those services. ``stackrc``
sources the ``localrc`` section of ``local.conf`` to perform the default
overrides.
DATABASE\_TYPE
Select the database backend to use. The default is ``mysql``,
``postgresql`` is also available.
ENABLED\_SERVICES
Specify which services to launch. These generally correspond to
screen tabs. The default includes: Glance (API and Registry),
Keystone, Nova (API, Certificate, Object Store, Compute, Network,
Scheduler, VNC proxies, Certificate Authentication), Cinder
(Scheduler, API, Volume), Horizon, MySQL, RabbitMQ, Tempest.

Other services that are not enabled by default can be enabled in
``localrc``. For example, to add Swift, use the following service
names:
::
enable_service s-proxy s-object s-container s-account
A service can similarly be disabled:
::
disable_service horizon
Service Repos
The Git repositories used to check out the source for each service
are controlled by a pair of variables set for each service.
``*_REPO`` points to the repository and ``*_BRANCH`` selects which
branch to check out. These may be overridden in ``local.conf`` to
pull source from a different repo for testing, such as a Gerrit
branch proposal. ``GIT_BASE`` points to the primary repository
server.
::
NOVA_REPO=$GIT_BASE/openstack/nova.git
NOVA_BRANCH=master
To pull a branch directly from Gerrit, get the repo and branch from
the Gerrit review page:
::
git fetch https://review.openstack.org/p/openstack/nova refs/changes/50/5050/1 && git checkout FETCH_HEAD
The repo is the stanza following ``fetch`` and the branch is the
stanza following that:
::
NOVA_REPO=https://review.openstack.org/p/openstack/nova
NOVA_BRANCH=refs/changes/50/5050/1
