访问att.iTems循环中的stat.sisits

Question

我正在尝试创建一个脚本，该脚本将禁用/启用repolist中列出的所有CentOS7存储库。

我想在尝试对其进行编辑之前先检查回购文件 - 使用替换。

我的想法是拥有一个2D列表包含文件的名称以及是否存在。例如[centos-base.repo，true]

我已经成功创建了一个将执行此操作的脚本，但是它使用了include_tasks。理想情况下，我想在一个文件中拥有所有功能。

我收到此错误：

TASK [DEBUG  Indexes] ******************************************************************************************************************************************
fatal: [localhost]: FAILED! => {"msg": "The task includes an option with an undefined variable. The error was: 'results' is undefined\n\nThe error appears to be in '/root/defaultRepoTest.yml': line 41, column 5, but may\nbe elsewhere in the file depending on the exact syntax problem.\n\nThe offending line appears to be:\n\n\n  - name: DEBUG  Indexes\n    ^ here\n"}

从显示结果从输出中移出打印语句

TASK [DEBUG Show results] **************************************************************************************************************************************

代码文件： ---

  vars:
    repoList:

      - CentOS-Debuginfo.repo

    reposPresent: []

    enable: 0

  tasks:

  - name: Check if path exists
    stat:
      path: /etc/yum.repos.d/{{ item }}
    register: outcome
    with_items: "{{ repoList }}"

  - name: DEBUG Show outcome
    debug:
      msg: "{{ outcome }}"

  - name: DEBUG Show results
    debug:
      msg: "{{ outcome.results}}"

  - name: DEBUG  Indexes
    debug:
      msg: "{{ results.stat.exists }}"
    with_items: "{{ outcome }}"

我一定不能正确访问该元素。我希望调试索引语句能打印一个布尔值列表。然后，我可以将它们添加到2D列表中。

Answer 1

您的最后一个调试任务应该是

    - name: DEBUG  Indexes
      debug:
        msg: "{{ item.stat.exists }}"
      with_items: "{{ outcome.results }}"
