5.2.1. General Guidelines for Heat

This section contains general Heat Orchestration Template guidelines and requirements. Heat Template Compliance

The Heat Orchestration Template requirements with RFC 2119 keywords MUST and MUST NOT can be validated against a set of Heat Templates via the VNF Validation Program (VVP).

NOTE: Not all requirements are currently testable via VVP.

The VVP validation scripts project contains python validation scripts that will parse Heat Orchestration Templates in a given directory to ensure that they comply with ONAP Heat Orchestration Template requirements.

For instructions on how to use the VVP validation scripts, please see the validation scripts README YAML Format

Requirement: R-95303 ../../_images/arrow-right-circle.svg
target: VNF
keyword: MUST
validation_mode: static
A VNF’s Heat Orchestration Template MUST be defined using valid YAML.

YAML (YAML Ain’t Markup Language) is a human friendly data serialization standard for all programming languages. See http://www.yaml.org/.

YAML rules include:

  • Tabs are not allowed, use spaces ONLY
  • You must indent your properties and lists with 1 or more spaces
  • All Resource IDs and resource property parameters are case-sensitive. (e.g., “ThIs”, is not the same as “thiS”)
