apache - 为什么我收到错误 "You don' t have permission to access/on this server."？

Question

我尝试在 docker 上运行我的网站，这是我的 docker-compose.yml:

version: '2'
services:
  php:
    image: yiisoftware/yii2-php:7.1-apache
  volumes:
    - ~/projects/my-project-name.local/composer- 
    docker/cache:/root/.composer/cache:delegated
    - ./:/app:delegated
  ports:
    - '8000:80'

当我运行“docker-compose up -d --build”并打开一个 url localhost:8000 时，发生错误“Forbidden.You don't have permission to access/on this server.”
容器的日志是:

当我使用与 yii2 相同的 docker-compose.yml 时，一切正常。
请帮我解决这个问题。我的操作系统是 Ubuntu-18.04。

yii2 docker 镜像基于 php 镜像，在其 Dockerfile 中有以下几行:

# Copy the app code into the image
COPY . /var/www/html

这与日志中的警告一致。

当你把它添加到你的 Dockerfile 中时，你应该没问题(假设你的源代码在当前目录中)。

如果你想使用 docker 容器作为开发环境，你可以将源代码的文件夹挂载到 /var/www/html .在这种情况下，您必须添加一个卷:

volumes:
  - .:/var/www/html # Add this line
