- API server¶
HTTP REST API service for heat.
An abbreviated form of “AWS CloudFormation”.
When a resource must wait for another resource to finish creation before being created itself. Heat adds an implicit dependency when a resource references another resource or one of its attributes. An explicit dependency can also be created by the user in the template definition.
Used to affect the run-time behavior of the template. Provides a way to override the default resource implementation and parameters passed to Heat. See Environments.
- Heat Orchestration Template¶
A particular template format that is native to Heat. Heat Orchestration Templates are expressed in YAML and are not backwards-compatible with CloudFormation templates.
An acronym for “Heat Orchestration Template”.
