基于寄存器变量的输出创建新变量

Question

我希望任何人都能帮助我。我是新来的ansible，过去几天我一直在寻找解决方案，但没有运气。我想根据任务中寄存器变量的输出创建一个变量。

下面是我使用的变量：

ports:
 access:
 - int:
   - "Ethernet1/0"
   - "Ethernet1/1"
   voice: 10
   data: 100
 - int:
   - "Ethernet2/0"
   - "Ethernet2/1"
   voice: 11
   data: 101
 trunk:
 - int:
   - "Ethernet0/0"
   - "Ethernet0/1"
   allowed_vlans: "10,100,11,101"
   range: "range e0/0 - 1"

- name: show interface swicthport
  ios_command:
    provider: "{{ provider }}"
    commands:
    - show interface {{ item.1 }} switchport
  register: show_out
  with_subelements:
  - "{{ ports.trunk }}"
  - int
- debug: var=show

下面是调试的输出：

                ]
            ], 
            "warnings": []
        }, 

根据输出，如何设置一个值"Trunking已启用: ALL“的变量？

谢谢，谢谢您的回复。

编辑： @Konstantin我感谢您的帮助和耐心。你的回答是对的，只是我的问题不清楚，你对with_subelements的看法也是对的，不需要使用它。我编辑下面的任务。

- name: show interface swicthport
  ios_command:
    provider: "{{ provider }}"
    commands:
    - show interface switchport | include Name|Trunking VLANs Enabled
  register: show_out

调试输出：

TASK [debug] *******************************************************************
ok: [acc_sw_01] => {
"show_out": {
    "changed": false, 
    "stdout": [
        "Name: Et0/0\nTrunking VLANs Enabled: 11\nName: Et0/1\nTrunking VLANs Enabled: ALL"
    ], 
    "stdout_lines": [
        [
            "Name: Et0/0", 
            "Trunking VLANs Enabled: 11", 
            "Name: Et0/1", 
            "Trunking VLANs Enabled: ALL", 
        ]
    ], 
    "warnings": []
  }
}

如何根据输出创建字典或散列列表？类似于：

- name: "Et0/0"
  trunkning_vlans_enabled:11
- name: "Et0/1"
  trunking_vlans_enabled: all

  or     

  Eth0/0:
    trunking_vlans_enable: 11
  Eth0/1:
    trunkning_vlans_enable: all

谢谢

不确定您真正想要的是什么，但可以从下面的示例开始：

---
- hosts: localhost
  gather_facts: no
  vars:
    show_out:
      results:
        - item: Ethernet0/0
          stdout_lines: [
                [
                    "Name: Et0/0",
                    "Switchport: Enabled",
                    "Trunking VLANs Enabled: ALL",
                    "Appliance trust: none"
                ]
            ]
        - item: Ethernet0/1
          stdout_lines: [
                [
                    "Name: Et0/1",
                    "Switchport: Enabled",
                    "Trunking VLANs Enabled: ALL",
                    "Appliance trust: none"
                ]
            ]
  tasks:
    - debug:
        msg: "{{ show_out.results | map(attribute='stdout_lines') | map('first') | map('intersect',['Trunking VLANs Enabled: ALL']) | list }}"
