<para>To create a stack, or template, from an <link

|
xlink:href="https://github.com/openstack/heat-templates">example template
|
|
file</link>, run following command:</para>
|
|
<screen><prompt>$</prompt> <userinput><?db-font-size 75%?>heat stack-create mystack --template-file=/path/to/heat/templates/WordPress_Single_Instance.template \
|

|
<para>The <literal>--parameters</literal> values that you specify
|
|
depend on which parameters are defined in the
|
|
template. If the template file is hosted on a website,
|
|
you can specify the URL with
|
|
<literal>--template-url</literal> parameter
|
|
instead of the <literal>--template-file</literal>
|
|
parameter.</para>

<para>The command returns the following output:</para>
