Ansible：为什么我无法获得调试输出

我有以下剧本，我想获得调试输出：

---
- name: Install and configure chrony
  hosts: '{{ hostgroup  }}'
  gather_facts: no
  become: yes
  become_method: sudo

  tasks:
    - name: make sure chronyd is installed
      yum:
        name: chrony
        state: latest
        update_cache: yes
      register: command_output

    - name: Print result of install chronyd
      debug:
        var: command_output.stdout_lines

但这是我得到的：

[WARNING]: log file at /var/log/ansible.log is not writeable and we cannot create it, aborting

/usr/lib/python2.7/site-packages/requests/__init__.py:91: RequestsDependencyWarning: urllib3 (1.24.1) or chardet (2.2.1) doesn't match a supported version!
  RequestsDependencyWarning)

PLAY [Install and configure chrony] *********************************************************************************************************************************************************************************************************

TASK [make sure chronyd is installed] *******************************************************************************************************************************************************************************************************
ok: [serv8]

TASK [Print result of install chronyd] ******************************************************************************************************************************************************************************************************
ok: [serv8] => {
    "command_output.stdout_lines": "VARIABLE IS NOT DEFINED!"
}

PLAY RECAP **********************************************************************************************************************************************************************************************************************************
serv8               : ok=2    changed=0    unreachable=0    failed=0

我该如何修复剧本以获取调试输出？

答案1

改变

- name: Print result of install chronyd
  debug:
    var: command_output.stdout_lines

到

- name: Print result of install chronyd
  debug:
    var: command_output

stdout_lines属性仅存在于shell/command 模块上
