从 json 获取值

Question

我是新来的，也是 ansible 剧本的新手。我正在尝试获取我们的 F5 GTM/DNS 设备用于查询的所有 IP（不重要）。我在我的剧本中运行这个任务...

  tasks:
    - name: get gtm servers
      bigip_device_info:
        gather_subset: gtm-servers
        provider: "{{ providerA }}"
      register: out

下面是两个gtm-servers的输出，有很多。有两种不同类型的 gtm-servers，“product: bigip”和“product: generic-host”。如果是 bigip，我需要获取两个 IP（10.1.1.1 和 10.1.1.2）。如果它是通用主机，我不需要它。

    },

我已经试过了...

- name: fetch server ips
  set_fact:
    server_ips: "{{ out.gtm_servers | json_query('[*].{name: name}') }}"

但是当然它只会获取列表中的第一个名称，而不是包含 IP 的嵌套 addresses:name。而且我迷失了只获取 bigip IP 而不是通用主机 IP。非常感谢任何帮助。

例如

    - set_fact:
        server_ips: "{{ gtm_servers|
                        json_query('[?product==`bigip`].addresses[].name') }}"

给予

server_ips:
  - 10.1.1.1
  - 10.1.1.2
