Nginx Request redirection one container to another

Question

I am running two centos docker container using following compose file-

version: "2"
services:
  nginx:
    build:
      context: ./docker-build
      dockerfile: Dockerfile.nginx
    restart: always
    ports:
      - "8080:8080"
    command: "/usr/sbin/nginx"
    volumes:
      - ~/my-dir:/my-dir
  data:
    build:
      context: ./docker-build
      dockerfile: Dockerfile.data
    restart: always
    ports:
      - "8081:8081"
    command: "/usr/sbin/nginx"
    volumes:
     - ~/my-dir-1:/my-dir-1

I’m trying to redirect request http://host-IP:8080/my-data/ to the data container using nginx. Below is my Nginx configuration for nginx container

/etc/nginx/conf.d/default.conf

server {
    listen 8080;
  location / {
       root   /my-dir/;
       index  index.html index.htm;
       }
}

I am able to access my-dir directory using http://host-IP:8080 URL and my-dir-1 using http://host-IP:8081 URL, how can I configure Nginx to redirect request on data container using http://host-IP:8080/my-data URL

Answer 1

You can use a proxy

http {
  upstream data_container {
    server data:8081;
  }
  server {
    listen 8080;
    location / {
        root   /my-dir/;
        index  index.html index.htm;
    }
    location /my-data {
      proxy-pass http://data_container$request_uri;
    }
  }
}

Answer 2

try adding a / at the end of 8080 like below. It will no longer append "route" to the forwarded request now.

location /route {
    proxy_pass  http://127.0.0.1:8080/;
}
