Rendering & Preview
Preview rendered templates before deployment.
Preview Mode
Preview renders your template with actual variable values, showing exactly what will be deployed.
- Open template in editor
- Fill in variable values in sidebar
- Click Preview
- Review rendered configuration
Tip
Use preview with different variable combinations to verify all code paths.
Validation
NetStacks validates templates for:
- Syntax Errors - Invalid Jinja2 syntax
- Undefined Variables - Variables used but not defined
- Type Mismatches - Wrong variable types
- Empty Outputs - Templates that render to nothing
Validation runs automatically on save and shows errors inline in the editor.
