Docker – how to connect Laptop(localhost) to container

I want to know client_real_ip But always return 172.0.0.1 or My laptop_ip

How to solve ??

OS : m1 mac

–network host is not working

Here is my case

Client_ip : 111.111.1.1

MyLaptop_ip : 222.222.2.2

Docker_container_server_ip : 172.0.0.1

  1. The client will send a request to the container server

  2. Then the request will arrive at my laptop first and from my laptop it will be sent to the container.

  3. in container_server, request.client.host is always 172.0.0.1 or 222.222.2.2
    I don’t want this ip , I want to client_ip 111.111.1.1(real client ip)

I think we should be able to send the request coming to the laptop to the container as it is. So that Docker doesn’t convert it internally and send it

I think I need to tweak the docker settings, but I don’t know what to do.

    Host networking might help:

    Here is an example of a docker-compose.yml file:

    version: '3.4'

services:
  web:
    build: .
    command: runserver
    env_file:
      - .env
    volumes:
      - 'static:/opt/app/static:rw'
    ports:
      - 8080:8080
    network_mode: host  # Add this
volumes:
  static:

    A little update on your comment, please also consider this: container to host

    extra_hosts:
    - "host.docker.internal:host-gateway"

    It is because of the NAT that is done by Docker. Maybe this can help or you can also try https://docs.docker.com/network/host/.

    Note: Host networking mode only works on Linux Host. As for Docker for Mac and Windows has a small packaged Linux kernel on which it is actually run.
