<title>Configure the Image Service</title>
|
|
<para>The OpenStack Image Service enables users to discover,
|
|
register, and retrieve virtual machine images. Also known as
|
|
the glance project, the Image Service offers a
|
|
<glossterm baseform="RESTful">REST</glossterm> API that
|
|
enables you to query virtual machine image metadata and
|
|
retrieve an actual image. Virtual machine images made
|
|
available through the Image Service can be stored in a variety
|
|
of locations from simple file systems to object-storage
|
|
systems like OpenStack Object Storage.</para>
|
|
<important>
|
|
<para>
|
|
For simplicity this guide configures the Image Service to use the
|
|
<literal>file</literal> backend. This means that images uploaded to
|
|
the Image Service will be stored in a directory on the same system that
|
|
hosts the service. By default this directory is
|
|
<filename>/var/lib/glance/images/</filename>.
|
|
</para>
|
|
<para>
|
|
Ensure that the system has sufficient space available under this
|
|
directory to store virtual machine images and snapshots before
|
|
proceeding. At an absolute minimum several gigabytes of space should
|
|
be available for use by the Image Service in a proof of concept
|
|
deployment.
