为什么仅在构建 docker 图像时出现此错误

Question

我已经将我的 Laravel 应用程序从 6 更新到 7，然后是 8，没有出现任何问题。但是，当我尝试构建我的 docker 图像时，它在 composer install --no-dev -o 命令处失败了。如果我运行在我的终端中执行相同的命令，则没有错误。错误是

In Request.php line 335:
                                                                               
  Argument 1 passed to Symfony\Component\HttpFoundation\Request::create() mus  
  t be of the type string, null given, called in /app/vendor/laravel/framewor  
  k/src/Illuminate/Foundation/Bootstrap/SetRequestForConsole.php on line 32

用于构建镜像的命令是@docker build $(DOCKER_BUILD_ARG) -t $(IMAGE_TAG) -f $(DOCKERFILE) . 这似乎是 laravel 框架文件的问题。我用谷歌搜索了这个错误，但没有找到任何解决方案。我尝试运行 composer dump autoload，php artisan cache:clar 和 php artisan config:clear，none 这些解决了我的问题。

我的 docker 文件如下所示：

FROM armcanada/php7-mssql:latest

# Copy files
ADD . /app/
ADD php.ini /etc/php.ini
ADD arm-http.conf /etc/httpd/conf.modules.d/arm-http.conf

# Install app dependencies
RUN composer install --no-dev -o

# Fix permissions
RUN chmod -R 777 ./storage
RUN chmod -R 777 ./bootstrap/cache

# Cache route & views
RUN php artisan route:cache
RUN php artisan view:cache

CMD ["start_httpd"]

和我的 composer.json:

Answer 1

当我在运行 composer install 之前有 .env 文件时，我遇到了同样的错误，然后它工作正常

Answer 2

我设法通过编辑 app/config.php 文件解决了这个问题。错误是 url 键为空，所以我向 env() 函数添加了一个默认值：

'url' => env('APP_URL', 'default'),

为什么仅在构建 docker 图像时出现此错误

Why is this error occuring only when building the docker image

laravel

composer-php

docker
