為什么會出現錯誤“您無權訪問/在此服務器上。”？

Question

我嘗試在docker上運行我的網站，這是我的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'

當我運行“ docker-compose up -d --build”並打開url localhost：8000時，發生錯誤“ Forbidden。您無權訪問此服務器上的/”。 容器的日志為：

當我將docker-compose.yml與yii2 basic一起使用時，一切正常。 請幫助我解決此問題。 我的操作系統是Ubuntu-18.04。

yii2 docker鏡像基於php鏡像，並且在Dockerfile中包含以下幾行：

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

這與日志中的警告一致。

將其添加到Dockerfile時，應該沒問題（假設您的源代碼位於當前目錄中）。

如果要將Docker容器用作開發環境，則可以將源代碼的文件夾安裝到/var/www/html 。 在這種情況下，您必須添加一個卷：

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