How to execute laravel app in docker container?

  docker, question

I tried to access the execution results in the docker container from this machine. The following is my attempt:

step1.
A php-composer image was created using dockerFile.

FROM php:7
 
 RUN apt-get update
 RUN apt-get install curl
 RUN curl -sS  https://getcomposer.org/installer -o  composer-setup.php
 RUN php  composer-setup.php --install-dir=/usr/local/bin --filename=composer
 RUN apt-get install -y git

step2.
Create a container and execute laraverapp with the following command:

docker run -p 127.0.0.1:3000:8000 --name MyTest -dt php-composer to create a container
 docker cp laravelApp/ d4bbb5d36312:/usr/
 docker exec -it MyTest bash
 cd usr/laravelApp
 php artisan serve

Next, on terminal, I will see information about the successful execution of laravel app:

Laravel development server started: <http://127.0.0.1:8000>

However, when I visited 127.0.0.1:3000 with my browser, I could not get the result of execution.

May I ask why?

Monitoring in Containerhttp://127.0.0.1: 8000 only accepts requests in containers and needs to be started in the following way:

php artisan serve --host=0.0.0.0
