Reverse proxy NGINX Docker container to localhost

So how do you route reverse proxy and NGINX container traffic to your local machine?

This setup is based on Docker Compose so let’s first setup our docker compose file config.

version: '3'
services:
  nginx:
    image: nginx
    ports:
      - "80:80"
    volumes:
       - ./dev-env/nginx/dev.conf:/etc/nginx/conf.d/default.conf

And now, let’s take a look at our NGINX configuration

server {
    listen       80;

    location / {
        proxy_pass   http://host.docker.internal:4200;
    }

}

By using the hostname `host.docker.internal`, Docker will resolve it our localhost’s IP and NGINX will route traffic to it.
