php - 在lumen 5.6应用中找不到驱动程序错误(在docker + alpine linux + nginx + php-fpm 7.2中运行)

Question

我试图将数据库访问权限添加到我的Lumen 5.6应用程序中，该应用程序当前在以下LEMP Stack中的docker中运行:

Alpine Linux

PHP-FPM 7.2.x

NGINX

我的撰写文件如下所示:

version: '2.1'

services:

  webhooks-mysql:
    container_name: webhooks-mysql
    image: mysql:5.7
    restart: always
    environment:
      MYSQL_ROOT_PASSWORD: 123456
      MYSQL_DATABASE: webhooks
      MYSQL_USER: webhooks
      MYSQL_PASSWORD: 123456
    healthcheck:
      test: ["CMD", "mysqladmin" ,"ping", "-h", "localhost"]
      timeout: 20s
      retries: 10
    ports:
    - "33401:3306"

  webhooks-service:
    container_name: webhooks-service
    depends_on:
      webhooks-mysql:
        condition: service_healthy
    build: .
    mem_limit: 64M
    ports:
      - "9050:80"
    volumes:
      - ./:/app:cached

并且我的.env中包含以下内容:

APP_NAME=webhooks
APP_ENV=local
APP_DEBUG=true
APP_KEY=base64:123456=
APP_TIMEZONE=UTC

DB_CONNECTION=mysql
DB_HOST=webhooks-mysql
DB_DATABASE=webhooks
DB_USERNAME=webhooks
DB_PASSWORD=123456

最后;我的容器具有所有require依赖项:

php7 php7-fpm php7-mysqli php7-pdo php7-openssl php7-mbstring
php7-xml php7-tokenizer php7-json php7-openssl php7-curl php7-zlib 
php7-xml php7-phar php7-intl php7-dom php7-xmlreader php7-ctype 
php7-mbstring php7-gd php7-zip git nginx supervisor curl zip unzip

以及以下 Composer 软件包:

  "require": {
    "php": ">=7.1.3",
    "laravel/lumen-framework": "5.6.*",
    "vlucas/phpdotenv": "~2.2",
    "wikimedia/ip-set": "^1.2",
    "doctrine/dbal": "^2.8"
  }

当我尝试在容器中运行迁移时，出现以下错误:

/app # php artisan migrate

In Connection.php line 664: could not find driver (SQL: select * from information_schema.tables where table_schema = webhooks and table_name = )

In PDOConnection.php line 50: could not find driver

任何想法为什么我会收到此错误？

我已经验证了php-mysql / pdo扩展已加载，env值正确，等等...我似乎无法弄清楚。

由于docker镜像已被完全剥离，因此您可能会遇到更多依赖关系，我遇到了相同的问题并通过添加扩展名pdo_mysql以及现有扩展名(pdo，mysqli和mbstring)进行了修复。
