OpenStack Templates & Orchestration

OpenStack “Heat” templates provide a means of defining and managing groups of resources (instances, ports, block devices, etc). This is a relatively new service for TIG (we just rolled it out August 2014) so this documentation will evolve as our understanding evolves. for now the official documentation, such as it is, is likely the best source of information:

• Introductory user documentation is here: http://docs.openstack.org/user-guide/content/heat-stack-create.html

Note: while the documentation above focuses on the CLI there is an interface in the WebUI under “Orchestration” “Stacks”.

• A trivial example template is here: http://docs.openstack.org/icehouse/install-guide/install/apt/content/heat-verify.html

• The full template spec is here: http://docs.openstack.org/developer/heat/template_guide/index.html
