The compose file defines an application with an services `frontend`.
|
||
|
|
When deploying the application, docker-compose maps port 80 of the frontend service container to port 80 of the host as specified in the file.
|
||
|
|
|
||
|
|
## Deploy with docker-compose
|
||
|
|
|
||
|
|
```
|
||
|
|
$ docker-compose up -d
