Detailed Description

Heat provides orchestration of composite cloud applications using the CloudFormation API and templates for OpenStack. Heat has requested OpenStack incubation and is currently an OpenStack related project.

Benefit to Fedora

Heat provides a standardized method for OpenStack users to launch multiple applications in an OpenStack cloud from a template file describing the cloud application.


The feature is currently going through package review. the Heat implementation is high quality and secure, but still needs much work before it will be acceptable for incubation by the OpenStack community.

How To Test

  • Install and configure Folsom OpenStack on the system.
  • To test the feature, the Heat community recommends running through the Getting Started Guide.
  • The started guide explains the expected results of the feature.

User Experience

  • The user will notice an AWS CloudFormation API available via the heat CLI command.


Heat does not have any dependencies, so no negative user change will be noticed.

Heat depends on a functional OpenStack implementation, but currently work well with Essex. We will also work well with Folsom when it becomes more stable.

The full list of packages Heat depends upon are:

  • python-crypto
  • python-eventlet
  • python-glance
  • python-greenlet
  • python-httplib2
  • python-iso8601
  • python-keystoneclient
  • python-kombu
  • python-lxml
  • python-memcached
  • python-migrate
  • python-novaclient
  • python-paste
  • python-qpid
  • python-routes
  • pysendfile
  • python-sqlalchemy
  • python-webob

Contingency Plan

The feature could be removed entirely as a contingency plan if there are packaging or dependency problems with no ill effects.


  • All documentation is in the Heat project's Wiki.
