Python 从每个正在运行的Docker容器中提取IP地址和端口

对于我的服务，我尝试创建一个Python脚本，从所有运行的Docker容器中提取IP地址和端口：

我使用了以下命令：

import os
import json


##1. Find all container ID
container_id = os.popen('docker ps -q').read()


##2. inspect all container
copy_2_json = os.popen('docker container inspect $(docker ps -q)').read()
print(json.loads(copy_2_json))

你能帮我处理一下我该怎么做吗？ 我试图将输出保存到文本文件，但也没有成功

以下是json文件的外观：
