<title>Providing User Data to Instances</title>
<para><literal>User Data</literal> is a special key in the metadata
service which holds a file that cloud aware applications within
the guest instance can access. For example the <link
xlink:href="https://help.ubuntu.com/community/CloudInit"
>cloudinit</link> system is an open source package from Ubuntu
that handles early initialization of a cloud instance that makes
use of this <literal>user data</literal>.</para>
<para>This user-data can be put in a file on your local system and
then passed in at instance creation with the flag
<literal>--user-data &lt;user-data-file&gt;</literal> for
example:<screen>
<prompt>$</prompt> <userinput>nova boot --image ubuntu-cloudimage --flavor 1 --user-data mydata.file</userinput></screen></para>
