Moved listings for property keys and values into the CLI. Removed listing from Image, and replaced with reference. Edited Image Guide section, and added Compute config and image-show example. Partial-Bug: #1304114 Change-Id: I84bd59bab2eda16adbe80641fcb95c55959f5d9d

|
|
<para>Image metadata can help end users determine the nature of an image, and is used by
|
|
associated OpenStack components and drivers which interface with the Image Service.</para>
|
|
<para>Metadata can also determine the scheduling of hosts. If the <option>property</option> option
|
|
is set on an image, and Compute is configured so that the
|
|
<systemitem>ImagePropertiesFilter</systemitem> scheduler filter is enabled (default), then the
|
|
scheduler only considers compute hosts that satisfy that property.</para>
|
|
<note><para>Compute's <systemitem>ImagePropertiesFilter</systemitem> value is specified in the
|
|
<option>scheduler_default_filter</option> value in the
|
|
<filename>/etc/nova/nova.conf</filename> file.</para></note>
|
|
<para>You can add metadata to Image Service images by using the <option>--property
|
|
<replaceable>key</replaceable>=<replaceable>value</replaceable></option> option with the
|
|
<command>glance image-create</command> or <command>glance image-update</command> command. More
|
|
than one property can be specified. For example:</para>
|
|
<screen><prompt>$</prompt> <userinput>glance image-update <replaceable>img-uuid</replaceable> --property architecture=arm --property hypervisor_type=qemu</userinput></screen>
|
|
<para>Common image properties are also specified in the
|
|
<filename>/etc/glance/schema-image.json</filename> file. For a complete list of valid property
|
|
keys and values, refer to the <link
|
|
xlink:href="http://docs.openstack.org/cli-reference/content/"><citetitle>OpenStack
|
|
Command-Line Reference</citetitle></link>.</para>
|
|
<para>All associated properties for an image can be displayed using the <command>glance
|
|
image-show</command> command. For example:</para>
|
|
<screen><prompt>$</prompt> <userinput>glance image-show myCirrosImage</userinput>
