我正在尝试将https请求从某个容器发送到Web（而不是另一个容器），但是失败。
由于容器使用iptable，我尝试将端口：443重定向到端口：8443
我试图将其添加到Dockerfile
RUN iptables -t nat -A PREROUTING -p tcp --dport 443 -j REDIRECT --to 8443
bu我收到此消息：
/bin/sh: iptables: not found
请求：
consumer_response = requests.get('{}/consumers/'.format(admin_api), params=params, verify=(running_env != RUNNING_ENV_LOCAL))
错误：
HTTPSConnectionPool(host='MyHost', port=443): Max retries exceeded with url: /consumers/?custom_id=org%orgid%2Fuser%userid (Caused by NewConnectionError('<urllib3.connection.VerifiedHTTPSConnection object at 0x7f1ad2264090>: Failed to establish a new connection: [Errno 111] Connection refused',))"
我希望得到200：OK，但实际输出是：
HTTPSConnectionPool(host='MyHost', port=443): Max retries exceeded with url: /consumers/?custom_id=org%orgid%2Fuser%userid (Caused by NewConnectionError('<urllib3.connection.VerifiedHTTPSConnection object at 0x7f1ad2264090>: Failed to establish a new connection: [Errno 111] Connection refused',))"
