PHP Laravel容器化应用本地Docker正常，Azure部署后无法登录无日志

我正在将一款PHP Laravel应用通过Docker容器化，并部署为Azure Web App，应用使用Azure MySQL数据库。本地启动容器时可正常登录，laravel.log会生成日志；但相同镜像部署到Azure后，无法登录且laravel.log为空。

Dockerfile #

FROM php:8.2

RUN curl -sS https://getcomposer.org/installer | php -- \
     --install-dir=/usr/local/bin --filename=composer

COPY --from=composer:latest /usr/bin/composer /usr/bin/composer

RUN mkdir /app

COPY docker-entrypoint.sh /

RUN apt-get update && apt-get install -y zlib1g-dev \
    libzip-dev \
    libonig-dev \
    libxml2-dev \
    libpng-dev \
    unzip \
    dialog \
    npm \
    openssh-server \
    && echo "root:Docker!" | chpasswd \
    && chmod u+x ./docker-entrypoint.sh


RUN docker-php-ext-install pdo pdo_mysql sockets mbstring exif pcntl bcmath gd

ADD . /app

COPY sshd_config /etc/ssh/

WORKDIR /app

RUN mkdir -p storage/app/public/uploads

RUN mkdir -p storage/app/public/uploads/clients

RUN mkdir -p storage/app/public/uploads/projects

RUN chown -R www-data.www-data /app

RUN chmod -R 755 /app

RUN chmod -R 777 /app/storage

RUN composer install

EXPOSE 8000 2222

ENTRYPOINT ["/docker-entrypoint.sh"]

docker-entrypoint.sh #

#!/bin/bash

set -e
service ssh start
npm install --global gulp-cli@2.3
npm install
gulp
php artisan serve --host=0.0.0.0 --port=8000

已完成的排查：

• 检查容器内权限设置无异常
• 安装mariadb-client执行数据库查询，确认数据库连接正常
