不允许Playbook保存telnet显示运行命令到文件语法错误

Question

我正面临着我的游戏手册的语法问题。我试图使用ansible的telnet模块显示命令，如下所示：module.html#telnet-module --它工作得很好--但我的问题是，当我试图添加寄存器将输出存储到一个变量以保存到文本文件中时，它会给我一个错误，说明变量不存在，指示复制任务的错误行。

我尝试过添加空格，并对其做了一些更改，但错误仍在显示。

- 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

在两个任务之间放置这个块，并再次运行它，并使用输出编辑第一个帖子。

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

这是可能的：

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

若要在/etc/ansible/ansible.cfg中设置此输出，请使用Ansible 2.5+

stdout_callback = yaml
bin_ansible_callbacks = True
