Ansible Playbook 将 telnet show 运行 命令保存到文件语法错误

Question

我的 Ansible 剧本的语法存在问题。我正在尝试使用 show 命令使用 ansible 的 telnet 模块，遵循这个资源：https://docs.ansible.com/ansible/latest/modules/telnet_module.html#telnet-module 它工作正常但我的问题是当我尝试添加寄存器以将输出存储到变量以便稍后将其保存到文本文件时它给我一个错误，说该变量不存在指示复制任务的错误行.

我尝试添加空格并稍作更改，但仍然显示错误

- hosts: telnet
  gather_facts: true
  connection: local

  tasks:
   - name: run show commands
     telnet:
       user: cisco
       password: cisco
       login_prompt: "Username: "
       prompts:
         - "[>#]"
       commands:
         - terminal length 0
         - show version
     register: output


   - copy:
       content: "{{ output.stdout[0] }}"
       dest: "/home/user/telnettest.txt"

Answer 1

将此块放在您的 2 个任务之间，然后再次 运行，并使用输出编辑您的第一个 post。

 - debug:
     msg: "{{ output }}"

这是可能的：

- copy:
    content: "{{ output.output }}"
    dest: "/home/user/telnettest.txt"

为了获得漂亮的输出，请在您的 /etc/ansible/ansible.cfg、Ansible 2.5+

中进行设置

stdout_callback = yaml
bin_ansible_callbacks = True
