Heat-Translator

Revision as of 18:16, 19 May 2016 by Spzala (talk | contribs) (Enhancements made under 0.4.0 release)

Tool to translate non-heat templates to Heat Orchestration Template.

Overview

Heat-Translator is an Openstack project and licensed under Apache 2. It is a command line tool which takes non-Heat templates as an input and produces a Heat Orchestration Template (HOT) which can be deployed by Heat. Currently the development and testing is done with an aim to translate OASIS Topology and Orchestration Specification for Cloud Applications (TOSCA) templates to HOT. However, the tool is designed to be easily extended to use with any format other than TOSCA.

Architecture

Heat-Translator tool takes an in-memory graph from TOSCA Parser as an input, maps it to Heat resources and then produces a HOT.

Enhancements made under 0.3.0 release

OpenStack Nova flavor for TOSCA flavor constraints - until now there was a pre-defined set of flavors to use with translation but with this feature flavors are fetched dynamically from Nova, based on constraints defined in the TOSCA template, when run heat-translator in an OpenStack environment.

New option to only validate template - allows user to only validate TOSCA template file without running translation.

New option to save translation output to desired file – produces a ready to deploy HOT template.
