Configure Subdomains Nginx-proxy and Docker-compose

Question

I want to configure Nginx to access hosted services with a subdomain of my server. Those services and Nginx are instantiated with Docker-compose.

In short, when typing jenkins.192.168.1.2, I should access to Jenkins hosted on 192.168.1.2 redirected with Nginx proxy.

It is not working working a top domain name, but not locally with for example 192.168.1.2.

Can anyone help me with this query?

Thanks

Answer 1

Try any of the following methods:

you can just set your nginx to redirect like so:

location /jenkins {
    proxy_pass http://jenkins:8080;
    ...
}

location /other-container {
    proxy_pass http://other-container:8080;
}

which would allow you to access jenkins at 192.168.1.2/jenkins

---

Or you can serve your different containers through different ports. E.g:

server {
    listen 8081;
    location / {
        proxy_pass http://jenkins:8080;
        ...
    }
}

server {
    listen 8082;
    location / {
        proxy_pass http://other-container:8080;
        ...
    }
}

And then you can access Jenkins on port address 192.168.1.2:8081/.

I hope it will help you resolve your query.

If you are already using docker-compose I recommend using the jwilder nginx-proxy container.

https://github.com/jwilder/nginx-proxy

This allows you to add unlimited number of web service containers to the backend of the defined nginx proxy, for example:

nginx-proxy:
  image: jwilder/nginx-proxy
  ports:
    - "80:80"
    - "443:443"
  volumes:
    - "/etc/nginx/vhost.d"
    - "/usr/share/nginx/html"
    - "/var/run/docker.sock:/tmp/docker.sock:ro"
    - "nginx_certs:/etc/nginx/certs:rw"
nginx:
  build:
   context: ./docker/nginx/
   dockerfile: Dockerfile
  volumes_from:
     - data
  environment:
     VIRTUAL_HOST: www.host1.com
nginx_2:
  build:
   context: ./docker/nginx_2/
   dockerfile: Dockerfile
  volumes_from:
     - data
  environment:
     VIRTUAL_HOST: www.host2.com
apache_1:
  build:
   context: ./docker/apache_1/
   dockerfile: Dockerfile
  volumes_from:
     - data
  environment:
     VIRTUAL_HOST: www.host3.com
