Question

我正在Ansible剧本中设置一个新剧本，该剧本在一组机器上进行一些操作。这些操作需要以串行模式1 x 1播放。

我的工作在第一台机器上运行良好，但在其他机器上，似乎变量没有值。

  - name: "My play"  
    hosts: my_hosts_group   
    tags: [test]   
    serial: 1  
    become: yes   
    become_user: root   
    tasks:
        - shell: echo {{  MYVARIBLE.MYSOFTWARE.souche_path }} > /home/USER/test.txt
          register: result
        - debug: var=result

这是我的数据模型：

MYVARIBLE:
  MYSOFTWARE:
    souche_path: "/mybinpath/mybin"

对于第一台机器，它运行良好，并且我收到此消息：

ok: [host1] => {
    "changed": false, 
    "result": {
        "changed": true, 
        "cmd": "echo my_variable_value > /home/USER/test.txt", 
        "delta": "0:00:00.005541", 
        "end": "2019-04-26 16:27:09.415017", 
        "failed": false, 
        "rc": 0, 
        "start": "2019-04-26 16:27:09.409476", 
        "stderr": "", 
        "stderr_lines": [], 
        "stdout": "", 
        "stdout_lines": []
    }
}

但是要给他一个人，我得到这个：

fatal: [host2]: FAILED! => {}

MSG:

The task includes an option with an undefined variable. The error was: 'MYVARIABLE' is undefined

The error appears to have been in '/my playbook/install.yml': line 85, column 7, but may
be elsewhere in the file depending on the exact syntax problem.

The offending line appears to be:

  tasks:
    - shell: echo {{  MYVARIBLE }} >  /home/USER/test.txt
      ^ here
We could be wrong, but this one looks like it might be an issue with
missing quotes.  Always quote template expression brackets when they
start a value. For instance:

    with_items:
      - {{ foo }}

Should be written as:

    with_items:
      - "{{ foo }}"

exception type: <class 'ansible.errors.AnsibleUndefinedVariable'>
exception: 'MYVARIBLE' is undefined

我已在并行模式下播放它，并且运行良好。因此，我可以确定问题在于变量仅在第一个循环中被赋值。

我想念什么吗？
