Ansible: 플레이북에서 역할 재사용 시 핸들러 문제

에 만든 2016년 03월 22일 · 2코멘트 · 출처: ansible/ansible

문제 유형:

버그 신고
앤서블 버전:

ansible 2.0.0.2
  config file = /home/mickael/git/emq-devops/ansible/ansible.cfg
  configured module search path = Default w/o overrides

앤서블 구성:

해당 사항 없음

환경:

Ubuntu 14.04에서 Ansible 실행
OS 관리: CentOS 7

요약:

플레이북에서 역할을 재사용할 때 핸들러는 핸들러 작업 내에서 예상되는 역할의 변수 값을 사용하지 않습니다.

(예상된 동작인지 아닌지 잘 모르겠습니다. 핸들러가 정의될 때 핸들러에 사용된 변수가 대체되는 것이 의심됩니다.)

재현 단계:

https://github.com/mickael-ange/ansible-reports를 복제하고 다음을 실행합니다.

ansible-playbook playbooks/test-handlers-01.yml

예상 결과:

두 번째 핸들러 호출에는 item=test2 있습니다.

실제 결과:

실제 결과는 test_name 변수가 플레이북에서 재정의된 경우에도 두 핸들러 호출이 동일한 변수 값( item=test1 )을 사용한다는 것입니다.

최근에 수정했을 수도 있지만 가능한 한 빨리 살펴보겠습니다.

이것은 Ansible 2.1에서도 여전히 동일합니다.
핸들러가 다음과 같으면 실제로 동일한 역할을 두 번 이상 사용할 수 없습니다.

- name: delete varnish container
  docker:
    image: "{{ docker_varnish_image_tag }}"
    name: "{{ docker_varnish_container_name }}"
    state: absent
    docker_api_version: "{{ docker_api_version }}"

docker_varnish_container_name 변수는 플레이북에서 이 역할을 호출할 때마다 다릅니다.

- { role: docker_varnish, docker_varnish_container_name: varnish-apps }
- { role: docker_varnish, docker_varnish_container_name: varnish-cache }

하지만 플레이북에서 가장 먼저 정의된 이름의 컨테이너를 중지합니다.

핸들러 이름에 변수를 사용하려고 했지만 이 경우 전혀 트리거되지 않습니다.

최신 정보:
이 역할이 있는 경우에만 작동합니다.

- name: Set container name variable
  set_fact: docker_varnish_container_name={{container_name}}
  when: container_name is defined

그리고 이것은 플레이 북에서

- { role: docker_varnish, container_name: varnish-apps }
- { role: docker_varnish, container_name: varnish-cache }
