json - 如何使用匹配值在ansible中进行Json查询

Question

有人可以告诉我是否可以这样做吗？
我有以下 list

list:
  - dev
  - uat

我想遍历上面的列表并从下面的输出中获取相应 IpAddress 的值。

{
    "Tags": [
        {
            "ResourceType": "instance", 
            "ResourceId": "i-8dh7435490fjksfd", 
            "Environment": "production", 
            "IpAddress": "10.0.0.8"
        }, 
        {
            "ResourceType": "instance", 
            "ResourceId": "i-8dh7435dsj89jfe", 
            "Environment": "dev", 
            "IpAddress": "10.0.0.3"
        },
        {
            "ResourceType": "instance", 
            "ResourceId": "i-8dsdj456ovfvfd", 
            "Environment": "uat", 
            "IpAddress": "10.0.0.7"
        }
    ]
}

这是我正在寻找的输出

[
 "10.0.0.3",
 "10.0.0.7"
]

我正在尝试使用此过滤器 Tags| json_query('[*].IpAddress') 。但它给了我列表中的所有 IpAddress。

例如

- hosts: localhost
  vars:
    my_list: [dev, uat]
    my_Tags: [
        {
            "ResourceType": "instance", 
            "ResourceId": "i-8dh7435490fjksfd", 
            "Environment": "production", 
            "IpAddress": "10.0.0.8"
        }, 
        {
            "ResourceType": "instance", 
            "ResourceId": "i-8dh7435dsj89jfe", 
            "Environment": "dev", 
            "IpAddress": "10.0.0.3"
        },
        {
            "ResourceType": "instance", 
            "ResourceId": "i-8dsdj456ovfvfd", 
            "Environment": "uat", 
            "IpAddress": "10.0.0.7"
        }
    ]
  tasks:
    - debug:
        msg: "{{ my_Tags|selectattr('Environment', 'in', my_list)|
                 map(attribute='IpAddress')|list }}"

给

  msg:
  - 10.0.0.3
  - 10.0.0.7
