Add validation for substitute_mappings and a test example. The substitution is responsibility of an orchestrator so work needs to be done in heat-translator to translate substitute_mapping in HOT. Partially example of substitute_mappings is given in the test/data/topology_template/subsystem.yaml Refer to the spec section 'Using node template substitution for model composition' and related sections to read detail on the substitute_mappings. The related heat-translator blueprint is https://blueprints.launchpad.net/heat-translator/+spec/ nested-templates Partially-Implements: blueprint tosca-substitution-mappings Co-Authored-By: Sahdev Zala <spzala@us.ibm.com> Change-Id: I7baadef4f0b4c7cd426f710f4c74c198d02bc030 Signed-off-by: shangxdy <shang.xiaodong@zte.com.cn>
TOSCA Parser
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 or TOSCA Cloud Service Archive (CSAR) file 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 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 of TOSCA Parser from a separate tool, refer to the OpenStack heat-translator class TranslateTemplate located in the translator/osc/v1/translate.py module. The toscaparser/shell.py module of tosca-parser also provides a good reference on how to invoke TOSCA Parser from Command Line Interface.
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.
