Ubuntu下自建Invoice Ninja：创建账户后白屏问题求助

我正尝试在Ubuntu系统上通过Docker部署自建Invoice Ninja实例，克隆了dockerfiles/debian和invoiceninja两个仓库，文件结构如下：

invoiceninja/nginx  
invoiceninja/php  
invoiceninja/scripts  
invoiceninja/supervisor  
invoiceninja/Dockerfile  
invoiceninja/docker-compose.yml  
invoiceninja/app  
invoiceninja/bootstrap  
invoiceninja/config  
invoiceninja/database  
// Other Invoice Ninja files and folders  

我根据需求修改了docker-compose.yml、Dockerfile和nginx/laravel.conf文件，构建过程成功完成，但创建账户后应用显示白屏。

以下是我的修改内容：

修改后的Dockerfile #

# Copy local Invoice Ninja code
COPY . /var/www/html

# PHP modules (ensure these include all required extensions)
ARG php_require="bcmath gd mbstring pdo_mysql zip"
ARG php_suggest="exif imagick intl pcntl soap saxon-12.5.0"
ARG php_extra="opcache"

# Install system dependencies
RUN apt-get update && apt-get install -y --no-install-recommends \
    mariadb-client \
    gpg \
    supervisor \
    fonts-noto-cjk-extra \
    fonts-wqy-microhei \
    fonts-wqy-zenhei \
    xfonts-wqy \
    && apt-get clean \
    && rm -rf /var/lib/apt/lists/*

# Install PHP extensions (this includes zip, bcmath, gd)
COPY --from=ghcr.io/mlocati/php-extension-installer /usr/bin/install-php-extensions /usr/local/bin/

RUN install-php-extensions \
    ${php_require} \
    ${php_suggest} \
    ${php_extra}

# Install Composer
COPY --from=composer:latest /usr/bin/composer /usr/bin/composer

# Install dependencies
RUN composer install --no-dev --prefer-dist --optimize-autoloader

# Create symlink for frontend
RUN ln -s /var/www/html/resources/views/react/index.blade.php /var/www/html/public/index.html \
    && php artisan storage:link \
    && mv /var/www/html/public /tmp/public

USER www-data

修改后的docker-compose.yml #

services:
  app:
    build:
      context: .  # Use local files instead of pulling from a remote image
    restart: unless-stopped
    env_file:
      - ./.env
    volumes:
      - .:/var/www/html
      - app_cache:/var/www/html/bootstrap/cache
      - app_public:/var/www/html/public
      - app_storage:/var/www/html/storage

修改后的laravel.conf #

location ~ \.php$ {
    fastcgi_pass invoiceninja-app-1:9000;
    fastcgi_param SCRIPT_FILENAME $realpath_root$fastcgi_script_name;
    include fastcgi_params;
}

.env文件内容 #

DB_HOST="invoiceninja-mysql-1"
DB_DATABASE="ninja"
DB_USERNAME="ninja"
DB_PASSWORD="ninja"
DB_PORT="3306"
MYSQL_ROOT_PASSWORD="root"

压缩文件解压后运行以下命令即可启动：

docker-compose up --build -d

恳请帮忙运行并定位问题，若能提供修复建议将不胜感激。谢谢！
