Compose: nginx cannot get to client IP ?

[yi-huan]

Description of the issue

I use "docker-compose up" to run the php-nginx cannot obtain the client IP, the display is the gateway IP.

I've searched a lot of options, but I can't solve them.

Original ip is not passed to containers
Unable to retrieve user's IP address in docker swarm mode
Real remote IP adress

Mode 1

---

When I use "host" network mode, I don't know how to access my nginx.
./docker-compose.yml

version: '3.6'

services:
  php:
    image: php:7-fpm
    volumes:
      - ./web:/usr/share/nginx/html
    network_mode: "host"
  nginx:
    image: nginx:1-alpine
    volumes:
      - ./web:/usr/share/nginx/html
      - ./nginx.vh.default.conf:/etc/nginx/conf.d/default.conf:ro
    network_mode: "host"

docker-compose network_mode
ports

http://localhost/ cannot be accessed

---

Mode 2

---

host

I'm writing by this example, but I can't run it.
./docker-compose.yml

version: '3.6'

services:
  php:
    image: php:7-fpm
    volumes:
      - ./web:/usr/share/nginx/html
    networks:
      hostnet: {}
  nginx:
    image: nginx:1-alpine
    volumes:
      - ./web:/usr/share/nginx/html
      - ./nginx.vh.default.conf:/etc/nginx/conf.d/default.conf:ro
    networks:
      hostnet: {}
networks:
  hostnet:
    external: true
    name: host

use docker-compose up

use docker stack

Authenticate proxy with nginx

I tried to add the following to the location ~* \.php$ { } on the ./nginx.vh.default.conf file.

proxy_set_header  Host              $http_host;   # required for docker client's sake
proxy_set_header  X-Real-IP         $remote_addr; # pass on real client's IP
proxy_set_header  X-Forwarded-For   $proxy_add_x_forwarded_for;

But the client IP obtained is still the gateway IP.
