Ansible: 重用剧本中的角色时处理程序的问题

创建于 2016-03-22  ·  2评论  ·  资料来源: ansible/ansible
问题类型：
  • 错误报告
    Ansible 版本：
ansible 2.0.0.2
  config file = /home/mickael/git/emq-devops/ansible/ansible.cfg
  configured module search path = Default w/o overrides
Ansible 配置：

不适用

环境：

从 Ubuntu 14.04 运行 Ansible
管理操作系统：CentOS 7

概括：

在 playbook 中重用角色时，处理程序未在处理程序任务中使用预期角色的变量值。

（我不确定这是否是预期的行为。我怀疑在定义处理程序时会替换处理程序中使用的变量）

重现步骤：

克隆https://github.com/mickael-ange/ansible-reports并运行：

ansible-playbook playbooks/test-handlers-01.yml
预期成绩：

第二个处理程序调用将有item=test2 。

实际结果：

实际结果是两个处理程序调用都使用相同的变量值 ( item=test1 )，即使变量test_name已在剧本中重新定义。

我最近可能已经解决了这个问题，但我会尽快调查。

这仍然与 Ansible 2.1 相同
如果处理程序看起来像，我真的不能多次使用相同的角色

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

每次我在剧本中这样称呼这个角色时， docker_varnish_container_name变量都是不同的

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

但是它会停止名称在剧本中定义为第一个的容器。

我尝试在处理程序的名称中使用变量，但在这种情况下根本不会触发它们。

更新：
这只有在我有这个角色时才有效

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

这在剧本中

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