Php Docker mysql找不到驱动程序

我正在尝试在容器中运行laravel应用程序，但在迁移中找不到驱动程序。 Laravel 8、mysql 8、php 8

docker compose

它缺少一些扩展，我不知道是什么，也许我正在安装与PHP8不兼容的pdo？正确创建了用户和数据库

错误

注意：我在stackoverflow上尝试了许多不同答案的解决方案

谢谢大家!

phpinfo（）具有PDO（启用sqlite）、PDO_sqlite（3.27.2）和mysqlnd 8.0.6 这是我能看到的唯一的db驱动程序，可能与我使用docker compose添加的local.ini有关

这是local.ini

您能否通过以下示例之一确认驱动程序是否已实际安装来帮助我们？正如引用的注释中所指出的，结果如下：在var_dump（已定义（PDO:：MYSQL_ATTR_LOCAL_infle））上抛出一个错误；//mysql，未定义常量，加载扩展的PDO，true，PDO_-mysql（FALSE！），加载的扩展：核心ctype curl date dom fileinfo filter ftp hash iconv json libxml mbstring mysqlnd openssl pcre PDO PDO_sqlite Phar posix readline反射会话SimpleXML钠SPL sqlite3标准标记器xml xmlreader xmlwriter zlib--我有一些您可能会感兴趣的东西，但这可能与php的local.ini有关。不一定尝试删除docker-compose.yml中创建卷装入到.ini文件的行。确保重建图像以确保容器不读取文件。我看不出你的设置有任何明显的错误，我怀疑你是对的，有什么东西正在覆盖初始配置。您可能必须

rm

该卷才能将其与容器完全分离。
