<title>Create and manage services and service users</title>
<para>The Identity Service enables you to define services, as
follows:</para>
<itemizedlist>
<listitem>
<para>Service catalog template. The Identity Service acts
as a service catalog of endpoints for other OpenStack
services. The
<literal>etc/default_catalog.templates</literal>
template file defines the endpoints for services. When
the Identity Service uses a template file back end,
any changes that are made to the endpoints are cached.
These changes do not persist when you restart the
service or reboot the machine.</para>
</listitem>
<listitem>
<para>A SQL back end for the catalog service. When the
Identity Service is online, you must add the services
to the catalog. When you deploy a system for
production, use the SQL back end.</para>
</listitem>
</itemizedlist>
<para>The <literal>auth_token</literal> middleware supports the
use of either a shared secret or users for each
service.</para>
<para>To authenticate users against the Identity Service, you must
create a service user for each OpenStack service. For example,
create a service user for the Compute, Block Storage, and
Networking services.</para>
<para>To configure the OpenStack services with service users,
create a project for all services and create users for each
service. Assign the admin role to each service user and
project pair. This role enables users to validate tokens and
authenticate and authorize other user requests.</para>

<para>To create a service, run this command:</para>
<screen><prompt>$</prompt> <userinput>keystone service-create --name <replaceable>service_name</replaceable> --type <replaceable>service_type</replaceable> --description <replaceable>service_description</replaceable></userinput></screen>
<para>The arguments are:</para>
<itemizedlist>
<listitem>
<para><code><replaceable>service_name</replaceable></code>.
The unique name of the new service.</para>
</listitem>
<listitem>
<para><code><replaceable>service_type</replaceable></code>.
The service type, such as
<code>identity</code>,
<code>compute</code>,
<code>network</code>,

service identifier string.</para>
</listitem>
<listitem>
<para><code><replaceable>service_description</replaceable></code>.
The description of the service.</para>
