Docker – pdo_mysql（nginx + PHP7 + MariaDB + phpMyAdmin）Symfony + Doctrine

将pdo_mysql安装到我的docker容器中有点问题。

在Symfony中，我得到这个错误：

PDOException PDOException DriverException HTTP 500内部服务器错误驱动程序发生exception：无法find驱动程序

Symfony – config.yml

doctrine: dbal: driver: pdo_mysql 

Dockerfile

 FROM phpdockerio/php7-fpm:latest # Install selected extensions and other stuff RUN apt-get update \ && apt-get -y --no-install-recommends install vim mc apt-utils \ && php7-pdo_mysql php7-pdo \ && apt-get clean; rm -rf /var/lib/apt/lists/* /tmp/* /var/tmp/* /usr/share/doc/* WORKDIR "/var/www/project" 

泊坞窗，compose.yml

 version: "3.1" services: mysql: image: mariadb container_name: project-mariadb environment: MYSQL_ROOT_PASSWORD: root phpmyadmin: image: phpmyadmin/phpmyadmin container_name: project-pma restart: always links: - mysql ports: - 8183:80 environment: PMA_HOST: mysql PMA_USER: root PMA_PASSWORD: root webserver: image: nginx:alpine container_name: project-websrv working_dir: /var/www/project volumes: - ../../Sources/project/trunk/src/:/var/www/project - ./phpdocker/nginx/nginx.conf:/etc/nginx/conf.d/default.conf ports: - "8080:80" links: - php-fpm php-fpm: build: phpdocker/php-fpm container_name: project-php working_dir: /var/www/project volumes: - ../../Sources/project/trunk/src/:/var/www/project - ./phpdocker/php-fpm/php-ini-overrides.ini:/etc/php/7.0/fpm/conf.d/99- overrides.ini links: - mysql 

docker-compose ps

 d:\Work\DockerContainers\project>docker-compose ps Name Command State Ports --------------------------------------------------------------------------- project -mariadb docker-entrypoint.sh mysqld Up 3306/tcp project -php /bin/sh -c /usr/bin/php-fpm Up 9000/tcp project -pma /run.sh phpmyadmin Up 0.0.0.0:8183->80/tcp project -websrv nginx -g daemon off; Up 0.0.0.0:8080->80/tcp d:\Work\DockerContainers\project> 

我有这个Linux版本：

 PRETTY_NAME="Debian GNU/Linux 8 (jessie)" NAME="Debian GNU/Linux" VERSION_ID="8" VERSION="8 (jessie)" ID=debian 

我试图改变在Dockerfile中的pdo_mysql的包名称，我在论坛上发现，我试图通过直接在容器中安装apt-get安装，但没有任何帮助，我总是得到相同的消息：

 /bin/sh: 1: docker-php-ext-install: not found (docker-compose build) E: Unable to locate package php7-mysql (pdo_mysql etc.) (root in docker container) 

PHP-INI-overrides.ini

 upload_max_filesize = 100M post_max_size = 108M extension=pdo.so extension=pdo_mysql.so 

我不知道是Symfonyconfiguration中的这个问题还是Docker问题

你能帮我吗？

非常感谢
