Compose sample application
React application with a Spring backend and a MySQL database
Project structure:

services:

build: backend
...
db:
image: mysql:8.0.19

frontend:
build: frontend
ports:
- 3000:3000
...
The compose file defines an application with three services frontend, backend and db.
When deploying the application, docker-compose maps port 3000 of the frontend service container to port 3000 of the host as specified in the file.
Make sure port 3000 on the host is not already being in use.
Deploy with docker-compose
$ docker-compose up -d

Expected result
Listing containers must show three containers running and the port mapping as below:
$ docker ps
ONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
