Running laravel with docker compose

Question

I have installed Laravel (v8) in my local. And now I want to run it from docker. So in the root folder of Laravel, I created two files:

• docker-compose.yml
• Dockerfile

this is the content of docker-compose.yml:

version: '3.9'
services:
    laravel:
        build: .

and this is the content of Dockerfile

FROM php:7.4-fpm

COPY . /var/www
COPY . /var/www/html

WORKDIR /var/www

CMD php artisan serve --port=8080
EXPOSE 8080

and then, I run: docker-compose up -d --build after done, I open in browser http://localhost:8080 but the page does not work and shows error_empty_response. when I try run php artisan serve --port=8080 from CLI, and reopen browser.. the page is worked.

what I'm missing? can you help me? thanks before
