Heat-Translator

Tool to translate non-heat templates to Heat Orchestration Template (HOT).

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 project is mainly built of two components:

  1. Parser - parser for a particular template format e.g. TOSCA parser
  2. Generator - takes an in-memory graph from Parser, maps it to Heat resources and software configuration and then produces a HOT.

How To Use

Please refer to doc/source/usage.rst

Directory Structure

Three main directories related to the heat-translator are:

  1. toscalib: It is TOSCA parser for TOSCA Simple Profile YAML. It validates tosca input file and creates an in memory graphs.
  2. hot: It is the generator, that has logic of converting TOSCA in memory graph to HOT yaml files.
  3. common: It has all the file that can support the execution of parser and generator.
