services:
backend:
build: backend
ports:
- 80:80
- 9229:9229
- 9230:9230

db:
image: mysql:8.0.19

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 containers running and the port mapping as below:
$ docker ps
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
f3e1183e709e react-express-mysql_frontend "docker-entrypoint.s…" 8 minutes ago Up 8 minutes 0.0.0.0:3000->3000/tcp react-express-mysql_frontend_1

a434bce6d2be mysql:8.0.19 "docker-entrypoint.s…" 8 minutes ago Up 8 minutes 3306/tcp, 33060/tcp react-express-mysql_db_1
After the application starts, navigate to http://localhost:3000 in your web browser.
The backend service container has the port 80 mapped to 80 on the host.
$ curl localhost:80
{"message":"Hello from MySQL 8.0.19"}
Stop and remove the containers
$ docker-compose down
