Multiple docker services to listen on same host and port

问题

i am new to nginx and I am not sure is this normal behavior...

Here is the lib I am using: https://github.com/jwilder/nginx-proxy

I will explain here what I trying to accomplish...

I have 2 additional services service1 and service2 those services are simple node.js images with API endpoints

service1 have routes:
- service1/api/first
- service1/api/second
`

`
service2 have routes:
- service2/api/third
- service2/api/fourth
`

So is possible to be able to access this services from same host, like this:
localhost/service1/api/first
localhost/service2/api/third
?

I tried like this:

My `docker-compose.yml` file:


version: '2'
services:
  nginx-proxy:
    image: jwilder/nginx-proxy
    container_name: nginx-proxy
    ports:
      - "80:80"
    volumes:
      - /var/run/docker.sock:/tmp/docker.sock:ro

  whoami:
    image: jwilder/whoami
    environment:
      - VIRTUAL_HOST=whoami.local
  service1:
    image: mynode:1.1
    volumes:
        - .:/app
    restart: always
    environment:
      - VIRTUAL_HOST=service1.local
      - VIRTUAL_PORT=8080
  service2:
    image: mynodeother:1.2
    volumes:
        - .:/app
    restart: always
    environment:
      - VIRTUAL_HOST=service2.local
      - VIRTUAL_PORT=8081

Here is generated config file from command docker exec nginx-proxy cat /etc/nginx/conf.d/default.conf: http://pushsc.com/show/code/58f739790a58d602a0b99d22

Also when I visit localhost in browser I get:

Welcome to nginx!

If you see this page, the nginx web server is successfully installed and working. Further configuration is required.

Thank you for using nginx.

Try not to use IP addresses inside nginx config file. Also, you should use the same port number for both services: 8080 (if this is the port that nodejs application is listening).

Then you should properly define your routes to each service using location in each server context.

So, you should modify /etc/nginx/conf.d/default.conf inside nginx container like this:

# service1.local
upstream service1.local {
            ## Can be connect with "nginxproxy_default" network
            # nginxproxy_service1_1
            server service1:8080;
}

server {
    server_name service1.local;
    listen 80 ;
    access_log /var/log/nginx/access.log vhost;
    location /service1 { #note this line
        proxy_pass http://service1.local;
    }
}

# service2.local
upstream service2.local {
            ## Can be connect with "nginxproxy_default" network
            # nginxproxy_service2_1
            server service2:8080; #same port
}

server {
    server_name service2.local;
    listen 80 ;
    access_log /var/log/nginx/access.log vhost;
    location /service2 { #note this line
        proxy_pass http://service2.local;
    }
}
