来自输出的 Ansible 断言匹配字符串

问题描述

我有一个剧本可以从开关中检索“显示版本”输出，并且使用断言我想在输出中匹配一个字符串“NXOS：版本 9.3(6)”。如果成功，则打印成功消息，否则打印失败消息。使用以下脚本，我总是收到失败的消息。

--- 
- 
  connection: network_cli
  gather_facts: false
  hosts: LAB_LF
  tasks:
    - 
      name: "show commands"
      nxos_command: 
        commands: 
        - command: show version
      register: show_version
      ignore_errors: true

    - 
      debug: 
        msg: "{{ show_version }}"
      name: "display the output from switch"
    - 
      assert: 
        that:
          - "'NXOS: version 9.3(6)' in show_version.stdout"
        success_msg: "Passed: All Leaf have current OS"
        fail_msg: "Failed: wrong os"
      ignore_errors: yes
      when: inventory_hostname in groups['LAB_LF0304']
      name: "assert the output from switch"

开关的打印输出如下。由于数据结构很重要，我正在粘贴完整显示的输出
