I created a dockerFile and docker-compose.yml:

Dockerfile

FROM php:7
 RUN apt-get update -y && apt-get install -y libmcrypt-dev openssl
 RUN docker-php-ext-install pdo mcrypt mbstring
 RUN curl -sS  https://getcomposer.org/installer | php -- --install-dir=/usr/local/bin --filename=composer
 WORKDIR /app
 COPY . /app
 
 CMD php artisan serve --host=0.0.0.0 --port=8000
 EXPOSE 8000

docker-compose.yml

version: '3'
 services:
 web:
 build:
 context: .
 dockerfile: ./Dockerfile
 ports:
 - 3021:8000
 volumes:
 - ./laravel-app:/app

When I executedocker-compose up –force-recreate -dAfter that, laravel app will127.0.0.1:3021On the correct implementation.

I’ve seen many docker-composer articles on the Internet that encourage the minimization of container, so I want to ask.Is there any way to rewrite this docker-compose.yml using php and composer’s official image?

The following are my attempts:

version: '3'
 
 services:
 php:
 image: php:7-fpm
 ports:
 - "3021:8000"
 volumes:
 - ./laravel-app:/app
 composer:
 image: composer:latest
 volumes:
 - ./laravel-app:/app
 working_dir: /app
 command: ["install","php artisan serve --host=0.0.0.0"]
 depends_on:
 - php

After completing this docker-compose.yml, I will execute itdocker-compose up –force-recreate -d, however127.0.0.1:3021However, no information was captured on the website.

I’ll follow updocker-compose psAnddocker-compose log, found that composer’s container was not started with the following error information

Invalid argument php artisan serve --host=0.0.0.0. Use "composer require php artisan serve --host=0.0.0.0" instead to add packages to your composer.json.

May I know how to amend it?
