탬플릿(파일)을 작성해서 스택을 배포
스택 : 리소스들의 집합
탬플릿 : 변수등을 이용해서 리소스에 대한 정의
탬플릿 → 스택 → 리소스
탬플릿 작성 : openstack stack create
※ 정적스택 : 탬플릿에 리소스의 형태 및 크기를 고정
※ 동적스택 : 정적스택에 사용량에 대한 조건도 지정

| description | 중요 | 주석을 달아주는 부분 탬플릿의 용도 및 주의사항 등 |
| parameters | 중요 | 탬플릿에서 사용할 변수를 선언 탬플릿의 재사용성을 증가 |
| resources | 핵심 | 각 리소스에 대한 선언 종류, 개수, 할당량 등을 설정 |
| outputs | 선택 | 작업 결과에 대해 출력 값(항목) 설정 |
탬플릿 생성 (p678) https://docs.openstack.org/heat/ocata/template_guide/hot_spec.html
생성시 .yml .yaml 확장자로 생성
yaml 언어를 사용 (ansible에서도 사용, 들여쓰기 횟수에 따른 레벨 구분)
아래 .vimrc 파일을 생성하여 vim 에디터에서 yaml 들여쓰기 적용할 수 있음.
heat-stack.yml 파일에 파라미터 값을 변수로 선언해둠으로써 재사용이 용이하게 됨.

인스턴스 생성
