Redirect Traffic to Container From Nginx

General Discussions

Hello. I have used two docker-compose.yml files to create a meteor application using NginX and also nexcloud. I am able to see all my containers up and running. The meteor app is accessible using http and https, but my nextcloud and MariaDB are not accessible. I was told that I can modify the nginx.conf in my meteor app related container that redirects traffic to the next cloud container. Unfortunately I could not find a way to do so. I will be glad if you show me the way how to do so, in case someone knows about it. Thanks.

Hello,

How is your Docker Environment setup? Layer 7 Routing / Interlock? If yes you can do this in your docker-compose file, add this to the nginx service: com.docker.lb.redirects: “source,target”

If not here is something to help you:

Thanks a lot for your prompt response. Actually, The structure is as follows:
docker-compose.yml (1):
nginx (balances the load between the two nodes with the given URL to direct the traffic to the 80 and 443 ports)
node1
node2

docker-compose.yml (2):
next cloud
MariaDB

My problem is that I want to set up the nextcloud console to be redirected to port 8080 which I have set up the nextcloud on using one of the subdomains of nodes 1 and 2 URLs. Is there an easy fix for this issue?

Can you post the compose files?

Thanks. Sure. I have provided the two docker files below:

The main docker-compose for my web interface which is working normally:

version: "2"
services:
  nginx:
    build: ./nginx
    container_name: container-nginx
    restart: always
    links:
      - node1:node1
      - node2:node2
    ports:
      - "80:80"
      - "443:443"
    volumes:
      - "/etc/pki/tls/certs/:/etc/pki/tls/certs/"
      - "/etc/pki/tls/private/:/etc/pki/tls/private/"
  node1:
    image: robo-meteor-base
    container_name: app-node1
    restart: always
    env_file:
      - .env
    environment:
      - SETTINGS_FILE=/home/meteor/settings-production.json
      - ROOT_URL=https://www.example.com
      - MONGO_URL=mongodb://user:pass@example.com:27017/meteordb
      - BUNDLE_FILE=/home/meteor/code.tar.gz
    volumes:
      - ./images/production.tar.gz:/home/meteor/code.tar.gz
      - ./code/settings-production.json:/home/meteor/settings-production.json
  node2:
    image: robo-meteor-base
    container_name: app-node2
    restart: always
    env_file:
      - .env
    environment:
      - SETTINGS_FILE=/home/meteor/settings-production.json
      - ROOT_URL=https://www.example.com
      - MONGO_URL=mongodb://user:pass@example.com:27017/meteordb
      - BUNDLE_FILE=/home/meteor/code.tar.gz
    volumes:
      - ./images/production.tar.gz:/home/meteor/code.tar.gz
      - ./code/settings-production.json:/home/meteor/settings-production.json

The second docker-compose is for my next cloud to be accessed under a URL like https://www.example.com/nextcloud:

version: '2'

volumes:
  nextcloud:
  db:

services:
  mariadb:
    image: mariadb
    container_name: nextcloud_mariadb
    restart: always
    volumes:
      - ./db:/var/lib/mysql
    environment:
      - MYSQL_ROOT_PASSWORD=pass123
      - MYSQL_DATABASE=nextCloud
      - MYSQL_PASSWORD=admin
      - MYSQL_USER=admin

  nextcloud:
    image: nextcloud
    container_name: nextcloud_app
    ports:
      - 8080:80
    links:
      - mariadb
    volumes:
      - ./nextcloud:/var/www/html
    restart: always
