Compose sample application

React application with a NodeJS backend and a MySQL database

Project structure:

docker-compose.yaml

services:
  backend:
    build: backend
    ...
  db:
    image: mysql:5.7
    ...
  frontend:
    build: frontend
    ports:
    - 80:9000
    ...

The compose file defines an application with three services frontend, backend and db. When deploying the application, docker-compose maps port 80 of the frontend service container to port 9000 of the host as specified in the file. Make sure port 80 on the host is not already being in use.

Deploy with docker-compose

$ docker-compose up -d

Expected result

Listing containers must show containers running and the port mapping as below:

$ docker ps
CONTAINER ID        IMAGE                           COMMAND                  CREATED             STATUS              PORTS                NAMES

After the application starts, navigate to http://localhost:80 in your web browser to get a colorful message.

My New React App

The backend service container has the port 80 mapped to 8080 on the host.

$ curl localhost:8080
Hello Docker World
