Run multiple services with nginx reverse proxy

Requirement

• docker desktop
• basic knowledge of how docker works

Getting Started

What is nginx reverse proxy ?

• nginx reverse proxy can be simplified as client is accessing the site via nginx acting as the middleware between client and site

What is the benefit ?

• you can have multiple site under 1 nginx middleware

How to get started ?

• Create a new docker-compose.yml file
• Content of the docker-compose.yml

version: '3.7'

services:

  proxy:
    image: jwilder/nginx-proxy
    container_name: proxy-test
    ports:
      - "80:80"
      - "443:443"
    volumes:
      - /var/run/docker.sock:/tmp/docker.sock:ro

  container1:
    image: httpd:2.4
    container_name: container-1
    environment:
      - VIRTUAL_HOST:container1.com
    ports:
      - 8080:80

  container2:
    image: httpd:2.4
    container_name: container-2
    environment:
      - VIRTUAL_HOST:container2.com
    ports:
      - 8081:80

• after you have filled in the docker-compose.yml with the code above, save and run the file by using command

docker-compose up -d

• You can access the container by opening localhost:<port>, for this example it is running on localhost:8080 and localhost:8081

Conclusion

• As my writing has reached it's end, i would like to say thank you for reading this article and have a try playing around with nginx reverse proxy, maybe it will give you more ideas on how to manage your site deployment
