Parser for TOSCA Simple Profile in YAML.

Overview

The TOSCA Parser is an OpenStack project and licensed under Apache 2. It is developed to parse TOSCA Simple Profile in YAML. It reads the TOSCA templates and creates an in-memory graph of TOSCA nodes and their relationship.

Architecture

The TOSCA Parser takes TOSCA YAML template as an input, with optional input of dictionary of needed parameters with their values, and produces in-memory objects of different TOSCA elements with their relationship to each other. It also creates a graph of TOSCA node templates and their relationship. The support for parsing template within TOSCA CSAR is under development.

The ToscaTemplate class located in the toscaparser/tosca_template.py is an entry class of the parser and various functionality of parser can be used by initiating this class. In order to see an example usage, refer to the heat-translator class TranslateTemplate located in the translator/osc/v1/translate.py module.

The toscaparser/elements sub-directory contains various modules to handle various TOSCA type elements like node type, relationship type etc. The entity_type.py module is a parent of all type elements. The toscaparser directory contains various python module to handle service template including topology template, node templates, relationship templates etc. The entity_template.py is a parent of all template elements.

Development Meetings

The development team meets every Thursday at 1600UTC on IRC #openstack-heat-translator channel. Since the heat-translator and tosca-parser projects development team works closely, there is no separate IRC channel for TOSCA-Parser.
