Nginx Issue

[AhmedBoody]

Hi Erik, thanks for the great course, one of the bests on Pluralsight in my view. I try to follow it carefully to develop my own project and there is still one problem I cannot solve. When running project from docker-compose & past URL "http://id-local.globomantics.com:5200" it doesn't work & display a message "This page isn’t working"

Docker Compose :

version: '3.4'

services:
  reverseproxy:
    build:
      context: .
      dockerfile: nginx/nginx.Dockerfile
    depends_on:
      - globomantics.identityserver
    ports:
      - "5200:5100"

  globomantics.identityserver:
    image: ${DOCKER_REGISTRY-}globomanticsidentityserver
    build:
      context: .
      dockerfile: Globomantics.IdentityServer/Dockerfile
    environment:
      - ASPNETCORE_URLS=http://*:5000
    ports:
      - "5000:5000"

nginx.local.conf:

Hi Ahmed - Thanks for the kind words. I think the problem is that your nginx service and nginx conf file don't agree with one another. In your compose file you have 5200:5100 as the port mapping, but then in the nginx conf file you have listen 5001. The 5100 and 5001 values should be the same. I suspect that will do the trick. Let me know how it goes.

@dahlsailrunner Thanks for your quick response, I was shocked when I saw ports were not the same,as usual, the bug in front of our eyes but we go beyond it 😄
