Angular 5 + Laravel: Create a Debian Docker Container to Run

I'm developing an app where I'm using Angular 5 + Laravel and I want to know how can I generate a container and run on a debian image.

I was trying something like this in Dockerfile.txt:

FROM debian

WORKDIR /

ADD . /
## I want to exec the back-end server and run the Angular app so I'm trying to access the folder and exec each one of them manually
RUN cd angular-module ng serve --open cd laravel-module php artisan serve

EXPOSE 4200
