Vitrage Template Validation API

Vitrage Template Validation API

An API for validating templates

Problem description

We would like to be able to validate a single template (or several templates) through api before uploading it to Vitrage.

Proposed change

Create API to validate Vitrage templates in terms of content and syntax.

  1. By given a full path to template file, validate a single template.

  2. By given a full path to directory, validate all template files inside it.

The template validate API returns a result that contains the following fields:

  1. status - validation succeeded/failed

  2. file path - the full path to the template file

  3. description

  4. message - error message

  5. status code

Depends on the template validation blueprints


Tempest tests also need to be added in order to test:

  1. Validate single template

  2. Validate several templates

Documentation Impact

The new api should be documented
