如何使Docker apache2虚拟主机工作

我是docker的新手，我想在我的docker机器上设置一个virtualhost，以便以这种方式访问它

http://myapp.dev

或

*.myapp.dev

（接受任何子域）

我尝试了几件事，似乎都不管用

在

docker compose.yml

文件中设置虚拟主机环境变量

在我的项目根目录下创建一个apache2配置文件，并将其链接为docker compose中的一个卷（例如：

/php apache.conf:/et/apache2/site enabled/000 default.conf

并在我的主机的

/etc/hosts

文件中添加了

127.0.0.1 myapp.dev

这听起来很普通，所以我肯定错过了什么。 非常感谢您的帮助，以下是我的配置：

docker compose.yml

：

version: '3.5'
services:
    php-apache:
        build:
            context: ./php-apache
            args:
                uid: ${UID}
        container_name: laravel-app
        environment:
            - VIRTUAL_HOST=myapp.dev
            - VIRTUAL_PORT=8000
            - APACHE_RUN_USER=#${UID}
            - APACHE_RUN_GROUP=#${UID}
        volumes:
            - ./:/var/www/html
            # tried with the above line w/o success
            - ./php-apache.conf:/etc/apache2/site-enabled/000-default.conf
        ports:
            -  8000:80
        networks:
            backend:
                aliases:
                    - laravel-app
    mysql-db:
        image: mysql:5.7
        container_name: mysql-db
        volumes:
            - ./run/var:/var/lib/mysql
        environment:
            - MYSQL_ROOT_PASSWORD=my_rootpwd
            - MYSQL_DATABASE=my_db
            - MYSQL_USER=my_user
            - MYSQL_PASSWORD=my_pwd
        networks:
            backend:
                aliases:
                    - db
networks:
    backend:
        name: backend-network
