Get PHP container on port 8000 after php artisan serve - php

Question

I can't container to listen on port 8000, even after adding the port mapping on my docker-compose.yml file.
All relevant files can be found here: https://github.com/salvatore-esposito/laravel-dockerized
I ran the following commands: docker-compose exec app php artisan serve and it has run successfully.
Anyway if I go inside the container, curl works as expected, but it doesn't work from the outside. The connection gets refused.
I fetched the ip using docker-machine ip
Please note that I mapped the outside-inside port in my container via docker-compose.yml even if in the repository there si no map.
I tried to copy all files to a built image and launch:
docker run --rm -p 8000:8000 --name laravel salvio/php-laravel php artisan serve
and
docker exec -it laravel bash
Once more time if a run "curl localhost:80" and "curl localhost:8000" the former doesn't work and the latter it does whereas if I take the container's ip via docker inspect name_container and digit curl ip_of_container:8000 nothing.

When using docker-compose exec a command keeps running until it's interactive session is stopped(by using ctrl-c or closing the terminal) because it isn't running as a service. To be able to keep the following command running
docker-compose exec app php artisan serve
you would have to open 2 terminals, 1 with the command and 1 to connect to the container and ping port 8000
If you want to access your container port 8000 you would have to expose the port 8000 in the Dockerfile:
# rest of docker file
# Copy existing application directory permissions
#COPY --chown=www-data:www-data ./code /var/www/html
# Change current user to www-data
#USER www-data
# Expose port 9000 and start php-fpm server
EXPOSE 80
EXPOSE 80000
and map it to your host in docker-compose(file):
app:
build:
context: .
dockerfile: .config/php/Dockerfile
image: salvio/php-composer-dev
container_name: app
restart: unless-stopped
tty: true
environment:
SERVICE_NAME: app
SERVICE_TAGS: dev
working_dir: /var/www/html
ports:
- "80:80"
- "8000:8000"
volumes:
- ./code/:/var/www/html
- .config/php/php.ini:/usr/local/etc/php/conf.d/local.ini
networks:
- myproject-network
Please keep in mind php artisan serve binds to localhost:8000. This means this is only reachable within the container. Use
php artisan serve --host 0.0.0.0
to bind to the shared network interface. Checkout the following resources:
