Rackspace Private Cloud v4.2.1 offers a technology preview implementation for OpenStack Orchestration (Heat), which enables you to manage infrastructure and applications within OpenStack clouds. OpenStack Orchestration is not currently recommended for Rackspace Private Cloud production environments.
OpenStack Orchestration is a service that orchestrates cloud applications onto cloud resources using the OpenStack Heat Orchestration Syntax (HOT) template format, through an OpenStack ReST API. OpenStack Orchestration also provides compatibility with the AWS CloudFormation template format. More information about Orchestration is available on the OpenStack wiki at
The Rackspace Private Cloud implementation of Orchestration includes the following components:
OpenStack Orchestration is not included in the default Controller and all-in-one installations, but you can add Orchestration to your private cloud at any time by applying the
heat-all role to your Controller node.
heat-allrole to the Controller node's run list.
#knife node run_list add
It will take chef-client several minutes to complete the installation tasks. chef-client will provide output to help you monitor the progress of the installation.
OpenStack Orchestration is accessible through the Horizon dashboard and through the command line interface.
Generally, interactions with Orchestration through the command line interface provides better error handling and user interaction. Refer to the Heat commands chapter of the OpenStack End User Guide for documentation of the heat client.
The Orchestration page is accessed through the Project tab of the navigation bar. A repository of templates is maintained at
https://github.com/openstack/heat-templates; you may also wish to develop your own for your environment. When a template is launched, it will create a "stack" of one or more instances, which may be configured to run applications.
Follow this procedure to launch a stack from a URL, a template file, or by entering template information directly through the Horizon dashboard.
When the stack is complete, it will appear in the Stacks list. Any instances have been created by the template will appear on the Instances page.
