How to proxy to localhost app ?

[sucrecacao]

Hello,

I have only one server which runs nginx proxy manager and a simple web app running on localhost:5000

Is it possible to create a proxy from $my_server_ip_address -> localhost:5000 ?

For now I'm exposing my web on $my_server_ip_address:5000 and use proxy manager to proxy $my_server_ip_address:80 and $my_server_ip_address:443 to $my_server_ip_address:5000 and handle SSL certificate. Is this an OK configuration? I though it would be cleaner to not expose my web app at all to the web.

NPM runs in a docker container, which has its own ip address. So set the forward host as localhost:5000 in NPM won't work. Actually, if you set the forward host to localhost:81, NPM will proxy its own admin UI.

My solution is Setting a docker network and set the gateway (the host of docker) as forward host.

For example, I am hosting a service on port 8888 , so my docker-compose.yml is:

version: '3'
services:
  nginx:
    image: 'jc21/nginx-proxy-manager:latest'
    container_name: 'nginx'
    restart: unless-stopped
    ports:
      - '80:80'
      - '443:443'
    volumes:
      - ./NginxProxyManager/data:/data
      - ./NginxProxyManager/letsencrypt:/etc/letsencrypt
    networks:
      backend:
        ipv4_address: 172.16.0.4
 
networks:
  backend:
    ipam:
      config:
      - subnet: 172.16.0.0/24

And set the forward host in NPM to 172.16.0.1, port 8888.
