我如何使用ansible解析显示版本（cisco ios）中的元数据
How can I parse metadata from show version (cisco ios) using ansible
这是我的剧本
output.stdout 的 return 是一个列表，这就是为什么我用索引 0
来调用它
- name: "GENERATE VERSION REPORT"
hosts: all
gather_facts: false
roles:
- ansible-network.network-engine
tasks:
- name: CAPTURE SHOW VERSION
ios_command:
commands:
- show version
register: output
- name: Display output
debug:
var: output.stdout
- name: PARSE THE RAW OUTPUT
command_parser:
file: "/home/nettools/ansible/parsers/show_version.yaml"
content: "{{ output.stdout[0] }}"
- name: DISPLAY THE PARSED DATA
debug:
var: version_facts
这是 show_version.yaml 文件
我使用 regex101.com 检查，一切正常，但我得到所有键的空值。

为什么我得到的是空值？
我想你必须设置导出选项：
- name: match version values
pattern_group:
- name: match name
pattern_match:
regex: "^(\S+) uptime is"
content: "{{ item }}"
register: name
export: yes
如果没有这个指令，包含的变量和值将不会被发送回剧本进行进一步处理。
其次，我没有看到该实用程序包含以下内容：“{{ item }}”？
- name: match version values
pattern_group:
- name: match name
pattern_match:
regex: "^(\S+) uptime is"
register: name
我建议你玩剧本 -vvv（非常冗长）来解决一些匹配问题
所以我看到你设置了导出到 playbook json_template，我觉得也是对的..

我认为 ^ 它不被视为行首
你能试试：regex: "\n(\\S+) uptime is"
我在 pattern_group @frenchy 中使用 export yes 并在 facts 和
它运作良好。你说得对，我不需要物品。
