【问题描述】：

我正在尝试一劳永逸地完成一些任务并在此之后收集结果。这是我的剧本：

---
- hosts: node2
  gather_facts: yes 
  tasks:
    - name: 'Some long script no 1 on node2'
      shell: "time sleep $[ ( $RANDOM % 20 )  + 20 ]s" 
      async: 40
      poll: 0
      register: script1 

    - name: 'Another long script no 2 on node2'
      shell: "time sleep $[ ( $RANDOM % 20 )  + 20 ]s" 
      async: 40
      poll: 0
      register: script2

- hosts: node2
  tasks:
    - name: "Collect results"
      async_status:
        jid: loop_item.ansible_job_id
      loop:
        - script1
        - script2
      loop_control:
        loop_var: loop_item
      register: async_poll_results
      until: async_poll_results.finished
      retries: 30

当我运行它时，我收到以下错误：

PLAY [node2]     ****************************************************************************************************************************
TASK [Gathering Facts] ******************************************************************************************************************
ok: [hostname]

TASK [Some long script no 1 on node2] ***************************************************************************************************

failed: [hostname] (item=script2) => {"ansible_job_id": "loop_item.ansible_job_id", "attempts": 1, "changed": false, "finished": 1, "loop_item": "script2", "msg": "could not find job", "started": 1}
to retry, use: --limit @xxxxxxxxx

PLAY RECAP ******************************************************************************************************************************
hostname         : ok=4    changed=2    unreachable=0    failed=1

真的不知道为什么我会收到这个“找不到工作”。我首先尝试在本地运行这个“收集”任务，然后我发现这个作业结果存储在 node2 上，所以我在那里运行它。尝试收集或不收集事实。也试过了

hostvars['hostname'][loop_item][ansible_job_id]

但这给了我和这里一样的错误。

任何帮助将不胜感激！

PS。我正在运行 ansible 2.6.1

【解决方案1】：

如果有人在这里搜索此错误消息，“找不到工作”还有另一个原因。如果作业以become 运行，那么应该是async_status。如果您尝试 async_status for become-job 而不将 become 添加到 async_status 模块，它将失败并显示此消息。

你帮了我很多谢谢。

【解决方案2】：

请尝试以下正确报价::

   - hosts: localhost
     gather_facts: false
     tasks:
      - name: 'Some long script no 1 on node2'
        shell: "time sleep $[ ( $RANDOM % 20 )  + 20 ]s"
        async: 40
        poll: 0
        register: script1

      - name: 'Another long script no 2 on node2'
        shell: "time sleep $[ ( $RANDOM % 20 )  + 20 ]s"
        async: 40
        poll: 0
        register: script2

   - hosts: localhost
     tasks:
      - name: "Collect results"
        async_status:
           jid: "{{ loop_item.ansible_job_id }}"
        loop:
           - "{{ script1 }}"
           - "{{ script2 }}"
        loop_control:
           loop_var: loop_item
        register: async_poll_results
        until: async_poll_results.finished
        retries: 30
