This adds the launch-instance topic from the OpenStack
Installation Guide to the heat install-guide per [1],
as a follow-up to [2].

Includes various minor edits.

Launch an instance
~~~~~~~~~~~~~~~~~~
In environments that include the Orchestration service, you can create a stack
that launches an instance.
Create a template
-----------------
The Orchestration service uses templates to describe stacks.
To learn about the template language, see `the Template Guide
<http://docs.openstack.org/developer/heat/template_guide/index.html>`__
in the `Heat developer documentation
<http://docs.openstack.org/developer/heat/index.html>`__.
* Create the ``demo-template.yml`` file with the following content:
.. code-block:: yaml
heat_template_version: 2015-10-15
description: Launch a basic instance with CirrOS image using the
``m1.tiny`` flavor, ``mykey`` key, and one network.
parameters:
NetID:
type: string
description: Network ID to use for the instance.
resources:
server:
type: OS::Nova::Server
properties:
image: cirros
flavor: m1.tiny
key_name: mykey
networks:
- network: { get_param: NetID }
outputs:
instance_name:
description: Name of the instance.
value: { get_attr: [ server, name ] }
instance_ip:
description: IP address of the instance.
value: { get_attr: [ server, first_address ] }
Create a stack
--------------
Create a stack using the ``demo-template.yml`` template.
#. Source the ``demo`` credentials to perform
the following steps as a non-administrative project:
.. code-block:: console
$ . demo-openrc
#. Determine available networks.
.. code-block:: console
$ openstack network list
+--------------------------------------+-------------+--------------------------------------+
| ID | Name | Subnets |
+--------------------------------------+-------------+--------------------------------------+
| 4716ddfe-6e60-40e7-b2a8-42e57bf3c31c | selfservice | 2112d5eb-f9d6-45fd-906e-7cabd38b7c7c |

+--------------------------------------+-------------+--------------------------------------+
.. note::
This output may differ from your environment.
#. Set the ``NET_ID`` environment variable to reflect the ID of a network.
For example, using the provider network:
.. code-block:: console
$ export NET_ID=$(openstack network list | awk '/ provider / { print $2 }')
#. Create a stack of one CirrOS instance on the provider network:
.. code-block:: console
$ openstack stack create -t demo-template.yml --parameter "NetID=$NET_ID" stack
+--------------------------------------+------------+--------------------+---------------------+--------------+
| ID | Stack Name | Stack Status | Creation Time | Updated Time |
+--------------------------------------+------------+--------------------+---------------------+--------------+
| dbf46d1b-0b97-4d45-a0b3-9662a1eb6cf3 | stack | CREATE_IN_PROGRESS | 2015-10-13T15:27:20 | None |
+--------------------------------------+------------+--------------------+---------------------+--------------+
#. After a short time, verify successful creation of the stack:
.. code-block:: console
$ openstack stack list
+--------------------------------------+------------+-----------------+---------------------+--------------+
| ID | Stack Name | Stack Status | Creation Time | Updated Time |
+--------------------------------------+------------+-----------------+---------------------+--------------+
| dbf46d1b-0b97-4d45-a0b3-9662a1eb6cf3 | stack | CREATE_COMPLETE | 2015-10-13T15:27:20 | None |
+--------------------------------------+------------+-----------------+---------------------+--------------+
#. Show the name and IP address of the instance and compare with the output
of the OpenStack client:
.. code-block:: console
$ openstack stack output show --all stack

+--------------------------------------+---------------------------+--------+---------------------------------+
#. Delete the stack.
.. code-block:: console
