`DevStack `__ - `Overview `__ - `Changes `__ - `FAQ `__ - `git.openstack.org `__ - `Gerrit `__ 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. :: ENABLED_SERVICES=g-api,g-reg,key,n-api,n-crt,n-obj,n-cpu,n-net,n-cond,cinder,c-sch,c-api,c-vol,n-sch,n-novnc,n-xvnc,n-cauth,horizon,rabbit,tempest,$DATABASE_TYPE Other services that are not enabled by default can be enabled in ``localrc``. For example, to add Swift, use the following service names: :: enable_service s-proxy s-object s-container s-account A service can similarly be disabled: :: disable_service horizon Service Repos The Git repositories used to check out the source for each service are controlled by a pair of variables set for each service. ``*_REPO`` points to the repository and ``*_BRANCH`` selects which branch to check out. These may be overridden in ``local.conf`` to pull source from a different repo for testing, such as a Gerrit branch proposal. ``GIT_BASE`` points to the primary repository server. :: NOVA_REPO=$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
