<h2>stackrc <small>DevStack settings</small></h2>
<p><code>stackrc</code> 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.
<code>stackrc</code> sources the <code>localrc</code> section of
<code>local.conf</code> to perform the default overrides.</p>
</div>
<dl>
<dt>DATABASE_TYPE</dt>
<dd>Select the database backend to use. The default is <code>mysql</code>,
<code>postgresql</code> is also available.</dd>
<dt>ENABLED_SERVICES</dt>
<dd>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.
<pre>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,$DATABASE_TYPE</pre>
Other services that are not enabled by default can be enabled in
<code>localrc</code>. For example, to add Swift, use the following service names:
<pre>enable_service s-proxy s-object s-container s-account</pre>
A service can similarly be disabled:
<pre>disable_service horizon</pre></dd>
<dt>Service Repos</dt>
<dd>The Git repositories used to check out the source for each service
are controlled by a pair of variables set for each service.
<code>*_REPO</code> points to the repository and <code>*_BRANCH</code>
selects which branch to check out. These may be overridden in
<code>local.conf</code> to pull source from a different repo for testing,
such as a Gerrit branch proposal. <code>GIT_BASE</code> points to the primary repository server.
<pre>NOVA_REPO=$GIT_BASE/openstack/nova.git
NOVA_BRANCH=master</pre>
To pull a branch directly from Gerrit, get the repo and branch from the
Gerrit review page:
<pre>git fetch https://review.openstack.org/p/openstack/nova refs/changes/50/5050/1 && git checkout FETCH_HEAD</pre>
The repo is the stanza following <code>fetch</code> and the branch
is the stanza following that:
<pre>NOVA_REPO=https://review.openstack.org/p/openstack/nova
NOVA_BRANCH=refs/changes/50/5050/1</pre></dd>
