tnode1에 Ubuntu OS일 경우에만 FQDN 과 OS 버전 출력

7. 반복문+조건문을 함께 사용

아래의 여러 서비스들의 상태를 체크하는 시나리오를 구성한다.

  • rsyslog
  • ssh
  • cron
  • nginx

여러 서비스를 반복으로 체크하면서 Active상태와 Inactive상태의 서비스를 분류하여 출력한다.

첫번째 task에서 의 ``은 loop의 값

  • systemctl is-active rsyslog, systemctl is-active ssh, systemctl is-active cron ,systemctl is-active nginx

두번째 이후에서의 `` 은 결과 객체 전체

  • item.item = "rsyslog"
  • item.rc =0

  • item.stdout = "active"

8. apache2 패키지를 apt 모듈을 통해서 설치 시, 핸들러를 호출하여 service 모듈로 apache2를 재시작해보자

apt cache를 업데이트 한 후 apache2 패키지를 인스톨한다.

다만 handler의 경우 요청하는 태스크의 변화가 있을시에만 호출되므로 처음 실행에 정상적으로 인스톨이 되었다면 다음 작업부터는 이미 apache2가 정상적으로 인스톨 되어있으므로 핸들러가 호출되지 않는다.

9. block rescure always 키워드를 사용한 플레이북을 작성하여 테스트

block

  • Print a message 실행 : 정상 실행됨
  • Force a failure 실행 : 실패하였으므로 rescue로 넘어감
  • Never print this : 위의 Force a failure 태스크에서 실패하였으므로 절대 실행하지 않음

rescue

  • Print when errors 실행
  • Force a failure in middle of recovery! >:-) : 실패
  • ‘Never print this’ : 마찬가지로 위의 태스크가 실패하였으므로 절대 실행하지 않음

always

  • Always do this : 위 태스크의 실패여부와 상관없이 항상 실행됨
