<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.
|
|
You can store virtual machine images made available through the
|
|
Image Service 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> back end. This means that images
|
|
uploaded to the Image Service are 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>Before you proceed, ensure that the system has sufficient
|
|
space available in this directory to store virtual machine
|
|
images and snapshots. At an absolute minimum, several gigabytes
|
|
of space should be available for use by the Image Service in a
|
|
proof of concept deployment. To see requirements for other back
|
|
ends, see <link
