템플릿 모듈은 템플릿을 더 효율적으로 만들 수 있는 특정 기능을 수행하는 도우미 파일입니다. 예를 들어 리소스에 대해 고유 이름을 생성하는 모듈을 사용할 수 있습니다. Deployment Manager는 Python 또는 Jinja로 작성된 모든 모듈을 실행할 수 있습니다.
그런 후 이 템플릿을 가져와서 모듈로 사용할 수 있습니다. Jinja 템플릿에서는 다음과 같은 모듈을 사용할 수 있습니다.

그러면 구성에서 두 파일을 가져와야 합니다(helpers/common.jinja 파일 포함).

Deployment Manager 서비스가 구성을 확장하고 최종 구성이 다음과 같이 표시됩니다.
Python에서 도우미 템플릿(이 예시에서는 helpers/common.py로 이름이 지정됨)은 다음과 같이 표시됩니다.

다음은 보다 복잡한 도우미 모듈입니다.
