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.
ℹ️ INFO For compatibility purpose between
AMD64andARM64architecture, we use a MariaDB as database instead of MySQL. You still can use the MySQL image by uncommenting the following line in the Compose file#image: mysql:8.0.27
$ docker compose up -d
