 The compose file defines an application with one service `angular`. The image for the service is built with the Dockerfile inside the `angular` directory (build parameter).
 
 When deploying the application, docker compose maps the container port 4200 to the same port on the host as specified in the file.
 Make sure port 4200 is not being used by another container, otherwise the port should be changed.
