标签未应用于 Ansible 包含的角色

  • 772

我创建了一个简单的 Ansible 剧本：

---
- hosts: all

  tasks:
    - name: Install Icinga2 on Windows
      include_role:
        name: my.icinga2.role
        apply:
          tags:
            - install-icinga2

该角色包含此任务文件：

---
- include_tasks: vars.yml
  tags: ['always']

- include_tasks: install.yml
  tags: ['install-icinga2-stack', 'install-icinga2']

- include_tasks: ido-install.yml
  when: icinga2_ido_enable == true
  tags: ['install-icinga2-stack', 'install-icinga2-ido']  

- include_tasks: configure.yml
  tags: ['install-icinga2-stack']

[...]

这是我执行剧本时的结果：

me@ansible:~/ansible$ ansible-playbook plays/icinga2-client-win.yml -i staging.ini --limit windows

为什么包含configure.yml角色任务文件，因为只有在我应用install-icinga2-stack标签并且我正在应用install-icinga2时才应该包含它？

此外，我意识到不包含ido-install.yml角色任务文件只是因为icinga2_ido_enable变量不在true此剧本中（默认为false），而不是因为未应用其标签之一（这应该是我想要的） .

我哪里错了？

    在include_role中应用标签意味着标签

    将应用于包含内的任务。

    换句话说，被包含角色中的任务将继承应用的标签。期望应用的标签会选择任务是一种误解。要在命令行或 Ansible 配置设置中选择任务使用--tags和，请使用和选项。--skip-tagsTAGS_RUNTAGS_SKIP

    include_role的文档中没有明确提到一个重要的事实。仅当整个任务为 时，参数应用tags: always标签才有效。这仅在示例中显示。

        - name: Apply tags to tasks within included file
      include_role:
        name: install
        apply:
          tags:
            - install
      tags:
        - always

    例子

    让我们有 2 个任务的角色 1

        shell> cat roles/role1/tasks/main.yml 
    - debug:
        msg: 'This is task 2'
      tags: task2
    
    - debug:
        msg: 'This is task 3'
      tags: task3

    和一本剧本

        shell> cat play1.yml 
    - hosts: localhost
      tasks:
        - debug:
            msg: 'This is task 1'
          tags: task1

        - include_role:
            name: role1
            apply:
              tags: role1
          tags: always

    如果我们在没有任何选项的情况下运行剧本，则所有任务都包括在内

        shell> ansible-playbook play1.yml | grep msg
        "msg": "This is task 1"
        "msg": "This is task 2"
        "msg": "This is task 3"

    请参阅下面的其他变体

        shell> ansible-playbook play1.yml --tags task1 | grep msg
        "msg": "This is task 1"
    shell> ansible-playbook play1.yml --tags task2 | grep msg
        "msg": "This is task 2"
    shell> ansible-playbook play1.yml --tags role1 | grep msg
        "msg": "This is task 2"
        "msg": "This is task 3"
    shell> ansible-playbook play1.yml --skip-tags role1 | grep msg
        "msg": "This is task 1"
    shell> ansible-playbook play1.yml --tags role1 --skip-tags task2 | grep msg
        "msg": "This is task 3"

    注意。标签列表未按预期工作。

        shell> ansible-playbook play1.yml --list-tags
    playbook: play1.yml
      play #1 (localhost): localhost    TAGS: []
          TASK TAGS: [always, task1]

    （备案：带有应用标签的 include_role 不起作用 #52063）
