ntc-ansible "response" 和 "module_args" (如何访问?)

ntc-ansible "response" and "module_args" (how access?)

我在 Ansible 中使用 networktocode ntc-ansible 模块来控制 Cisco IOS 设备(目前是交换机)。我可以成功地使用 ntc_show_Command 获取 'show version' 和 'show ip int brief' 并将结果放入本地文件。但是当我在 ansible-playbook 命令末尾使用 -vvv 时,我在终端中看到了结构化的 JSON 输出。如何从 ntc_show_command 访问 "module_args" 和 "response",即。如果我使用 "show ip int brief" 并且我想知道 int gi1/0/5 的状态。我怎样才能访问它?然后...我使用什么 playbook 命令 would/could 来获取我正在寻找的特定数据?

这是我使用-vvv 运行 剧本时可以看到的输出,但我不知道如何访问结构化数据

        "module_args": {

    },

        {
            "intf": "Vlan1",
            "ipaddr": "y.y.y.y",
            "proto": "down",
            "status": "administratively down"
        },
        {

            "ipaddr": "x.x.x.x",
            "proto": "up",
            "status": "up"
        },
TRUNCATED...

这是本地文件中 Show ip int brief 的输出。

Interface              IP-Address      OK? Method Status                
Protocol
Vlan1                  172.16.x.xxx    YES NVRAM  administratively down down
Vlan2                  192.168.x.xxx   YES NVRAM  up                    up
Vlan10                 10.10.yy.xxx      YES NVRAM  administratively down down

这是我的戏...

UPDATE 我根据这样的建议更新了代码:

我取得了进步,但我似乎仍然缺少一些重要的东西。我的第一个调试语句(如下)正在输出完整的输出(此处未显示),这是有效的。我可以set_fact成功到'interfaces'。我可以遍历 interfaces 变量并检测使用 when 语句设置的条件,我将其更改为查找所有 up/up 接口。但是...我的输出(如下所示未显示您显示的详细信息。我的输出显示(item=None)所有符合条件的项目,但不是您的输出显示的详细信息(您的原始答案中的第二个代码块)。
已更新 - 我将调试变量修改为 'item.intf',现在我得到了 intf 名称,但仍然不是所有细节。

**问题:如何获取仅显示符合条件的接口的输出?这个结构化数据可以保存到文件中吗?

更新 2::: 我能够使用复制模块将 {{ interfaces }} 作为结构化数据复制到文件中,但是当我尝试只显示接口而不显示其余数据时,而是使用 {{ interfaces.intf }我得到一个错误。 (见下文)

问题:如何获得仅显示接口名称的输出/文件?
问题:如何获得仅显示 up/up 接口名称的输出/文件?

我的第二个调试语句(下方)正在输出这个,它标识了 up/up 接口: UPDATED

skipping: [VTgroup_SW] => (item=None)
ok: [VTgroup_SW] => (item=None) => {
    "item.intf": "Vlan2"
}
skipping: [VTgroup_SW] => (item=None)

skipping: [VTgroup_SW] => (item=None)
ok: [VTgroup_SW] => (item=None) => {

剧本补充 更新 2

您需要注册输出,然后开始使用调试和 set_fact 来检索您要检索的数据结构元素:

这里我注册输出然后只检索'FastEthernet4'接口

- name: Cisco IOS Automation
  hosts: pynet-rtr1
  connection: local
  gather_facts: no

  tasks:
    - name: VERIFY INTERFACES
      ntc_show_command:
        connection: ssh
        platform: "cisco_ios"
        command: 'show ip interface brief'
        host: "{{ ansible_host }}"
        username: "{{ ansible_user }}"
        password: "{{ ansible_ssh_pass }}"
        use_templates: True
        template_dir: '/home/kbyers/ntc-templates/templates'
      register: output

    - debug:
        var: output

    - set_fact:
        interfaces: "{{ output.response }}"

    - debug:
        var: item
      when: '"FastEthernet4" in item.intf'
      loop: "{{ interfaces }}"

您可以再次执行另一个 set_fact 并仅保存此 FastEthernet4 接口,然后查看 'proto' 和 'status' 字段(即 'up' 和 'up').

这是执行结束时的样子:
