DevOps 철학

  • 문화(Culture) - 하나의 문화를 만들어 나가기
  • 자동화(Automation) - 자동화를 통해 효율성과 빠른 속도를 지향하기
  • 측정(Measurement) - 지표를 측정하여 지속적으로 개선하기
  • 공유(Share) - 공유를 통한 발전
  • 축적(File Up & Pile Up) - 기록을 축적하고 더욱 개선하기

lifecycle​

  • create_before_destory : 리소스 수정 시 신규 리소스를 우선 생성하고 기존 리소스를 삭제
  • prevent_destroy: 해당 리소스를 삭제하려 할 때 명시적으로 거부
  • ignore_changes : 리소스 요소에 선언된 인수의 변경 사항을 테라폼 실행 시 무시
  • precondition : 리스트 요소에 선언된 인수의 조건을 검증
  • postcondition: Plan과 Apply 이후의 결과를 속성 값으로 검증
