【问题描述】：

我编写了 ansible-playbook 来收集来自许多网络设备的结果。下面的剧本工作正常。但是如果我必须用很多命令来收集结果。假设有 20 个命令，我必须创建许多任务来将结果写入我的剧本中的文件。

目前，我手动创建要写入日志文件的任务。以下是 3 个命令的示例。

- name: run multiple commands and evaluate the output
  hosts: <<network-host>>
  gather_facts: no
  connection: local

  vars:
    datetime: " lookup('pipe', 'date +%Y%m%d%H') "
    backup_dir: "/backup/"

  cli:
    host: " ansible_host "
    username: <<username>>
    password: <<password>>

  tasks:
  - sros_command:
     commands:
       - show version
       - show system information
       - show port
     provider: " cli "
  register: result

- name: Writing output
  local_action:
    module: lineinfile
    dest: " backup_dir / inventory_hostname - datetime .txt"
    line: " inventory_hostname :# show version\n result.stdout[0] "
    create: yes
  changed_when: False

- name: Writing output
  local_action:
    module: lineinfile
    dest: " backup_dir / inventory_hostname - datetime .txt"
    line: " inventory_hostname :# show system information\n result.stdout[1] "
    create: yes
  changed_when: False

- name: Writing output
  local_action:
    module: lineinfile
    dest: " backup_dir / inventory_hostname - datetime .txt"
    line: " inventory_hostname :# show port\n cmd_result.stdout[2] "
    create: yes
  changed_when: False

是否可以在一个任务中循环命令和结果？

请多多指教。

谢谢

【参考方案1】：

在以上三个任务中单独尝试这一项任务..

- name: Writing output
  local_action:
    module: lineinfile
    dest: " backup_dir / inventory_hostname - datetime .txt"
    line: " inventory_hostname :# show  item.command \n cmd_result.stdout item.outnum  "
    create: yes
  changed_when: False
  with_items:
      -  command: version, outnum: [0] 
      -  command: system information, outnum: [1] 
      -  command: port, outnum: [2]

嗨阿普，谢谢你的帮助我收到错误“致命：[Network1]：失败！=> “msg”：“模板字符串时模板错误：预期令牌'打印语句结束' ， 拿到 ''。字符串： inventory_hostname :# show item.command \n cmd_result.stdout item.outnum ""

谢谢它对我很有帮助。

【参考方案2】：

下面的剧本对我有用

- name: Writing output
  local_action:
    module: lineinfile
    dest: " backup_dir / inventory_hostname - datetime .txt"
    line: " inventory_hostname :# show  item.command \n item.cmdoutput"
    create: yes
  changed_when: False
  with_items:
    -  command: "version", cmdoutput: " cmd_result.stdout[0] " 
    -  command: "system information", cmdoutput: " cmd_result.stdout[1] " 
    -  command: "port", cmdoutput: " cmd_result.stdout[2] "
