include_tasks

  • “include_tasks”를 활용한 skipping 줄이기
    4대정도의 서버에서는 크게 문제가 없겠지만 다수의 서버가 동작하는 환경에서 배포판에 맞지 않는 명령어를 전달하여 이를 확인한 뒤, skipping 하는 작업은 서버에 부담을 작용할 것이다. 이를 줄이기 위하여 “include_tasks”를 사용할 수 있다.

skipped가 전혀 발생하지 않았음!

Handers

  1. 직전 실행했던 파일의 결과를 확인하고 정상적으로 설치가 되었다면 웹을 통해 확인하기
  2. "1"에 문제가 없다면 removenginx.yaml 실행하기
  3. if 파일에 handler를 적용하여 각 노드에서 nginx가 설치된 뒤 어떤 버전인지 여부를 debug로 출력시켜 주세요.

주의해야 할 점! centos, ubuntu에서 공통적으로 nginx의 버전을 확인할 수 있는 명령??

  • 정상 배포 확인
  • removenginx
vagrant@control:~$ ansible-playbook removenginx.yaml
