任务结果到文件

Question

我有一个简单的剧本，运行Cisco nxos命令，剧本成功运行。想知道代码是什么，将所有结果保存到一个文件中，而不管我有多少主机，并使用Survey输入文件名。

目前，这是我的代码：

---

- name: run multiple commands on remote nodes
  nxos_command:
    commands:
      - show clock
      - show int status
      - show cdp neigh
      - show int desc
      - show port-channel summ
      - show vpc
      - show vpc role    

尝试使用代码

---

- name: run multiple commands on remote nodes
register: myshell_output

nxos_command:
 commands:
   - show clock
   - show int status
   - show cdp neigh
   - show int desc
   - show port-channel summ
   - show vpc
   - show vpc role
   

   - name: Saving data to local file
     copy:
       content: "{{ myshell_output.stdout|join('\n') }}"
       dest: "/tmp/hello.txt"
     delegate_to: localhost

它给了我一个错误：

FAILED! => {"msg": "The task includes an option with an undefined variable. The error was: 'ansible.utils.unsafe_proxy.AnsibleUnsafeText object' has no attribute 'stdout'\n\nThe error appears to be in '/tmp/awx_1869_7__9l_9l/project/roles/bcpcommands/tasks/main.yml': line 3, column 3, but may\nbe elsewhere in the file depending on the exact syntax problem.\n\nThe offending line appears to be:\n\n\n- name: run multiple commands on remote nodes\n  ^ here\n"}

主机通常我把它限制在极限柱上。文件的理想输出可能包含我输入的主机名和命令？

谢谢

你可能搞错了缩痕。尝试；

- hosts: my_host
  tasks:
    - name: run multiple commands on remote nodes
      nxos_command:
        commands: "{{ item }}"
      loop:
        - show clock
        - show int status
        - show cdp neigh
        - show int desc
        - show port-channel summ
        - show vpc
        - show vpc role
      register: myshell_output

    - debug:
        msg: "{{ myshell_output }}"

    - name: Saving data to local file and include hostname
      copy:
        content: "{{ myshell_output.stdout|join('\n') }} hostname: {{ inventory_hostname }}"
        dest: "/tmp/hello.txt"
      delegate_to: localhost

编辑主机名。

调试任务必须输出“stdout”消息。如果该任务不存在，那么您的复制任务将失败。
