Highlight the use of the 'file' Glance backend for storage and the default location that images will be stored under this scheme. Also provide some guidance on the amount of space this will require. Change-Id: I412c938d5f2151b3f3f76d47542d25d67c1c9869 Closes-bug: #1239516 backport: havana

<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 REST 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.
