```
|
||||
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

||||
