Docker 连接 nginx/php/mysql 的问题

Question

我正在尝试为本地环境的一些 PHP 项目设置一个 docker。我创建了docker-compose 文件：

############
## This is the LOCAL docker-compose. local is not in the file to make it default,
## easy for development.
############
version: '3.5'
services:
  nginx:
    build: ./docker/images/nginx
    image: project/nginx:latest
    ports:
      - "80:80"
    expose:
      - "80"
    volumes:
      - project_volume:/var/www/vhosts/abboom
    networks:
      project:
        aliases:
          - project.local.net
    environment:
       - VIRTUAL_HOST=project.local.net
  php:
    build: ./docker/images/php
    image: project/php:latest
    ports:
      - "7778:7778"
    expose:
      - "9000"
    volumes:
      - project_volume:/var/www/vhosts/project
    networks:
      - project
  workspace:
    build: ./docker/images/workspace
    image: project/workspace:latest
    volumes:
      - project_volume:/var/www/vhosts/project
    working_dir: /var/www/vhosts/project
    networks:
      - project
  redis_disk:
    build: ./docker/images/redis_disk
    image: project/redis:latest
    ports:
      - "6379:6379"
    volumes:
      - redis_data:/data
    networks:
      - project
  mysql:
    image: project/mysql:latest
    build: ./docker/images/mysql
    environment:
      MYSQL_ROOT_PASSWORD: secret
    volumes:
      - mysqldata:/var/lib/mysql
    networks:
      - project
    ports:
      - "33066:3306"
networks:
  project:
    name: project

volumes:
  mysqldata:
    driver: local
  redis_data:
    driver: local
  project_volume:
    driver: local
    driver_opts:
      type: nfs
      device: "$PWD/project"
      o: bind

也可能我需要为一个项目共享 nginx 虚拟主机（我从暂存服务器中获取了这个虚拟主机配置，可能需要进行更多更改？）

server {
    listen       80;
    server_name project.local.net;
    root         /var/www/vhosts/project/public;

    index index.php;

    access_log  /var/log/nginx/host.access.log  main;

    # redirect server error pages to the static page /50x.html
    #
    error_page   400 404 500 502 503 504  /500.html;
    location = /500.html {
    }

    location ~ /(assets/|content/|images/|stylesheets/|javascripts/|vendor/|fonts/|favicon.ico) {
    root          /var/www/vhosts/project/public;
    }

    location / {
            root           /var/www/vhosts/project/public;
            try_files $uri $uri/ /index.php?$args;
            fastcgi_pass   php:9000;
            fastcgi_index  index.php;
            fastcgi_param  SCRIPT_FILENAME   $document_root$fastcgi_script_name;
            include        fastcgi_params;

    }
}

所以问题是，当我尝试从浏览器访问该站点时，我收到了错误 Uncaught PDOException: could not find a driver in，但是当我从 worksapce 或 php 容器运行迁移时，一切都是工作正常。

我假设由于某种原因nginx 容器未与php 容器链接，并试图在nginx 容器中查找 pdo 驱动程序，而不是在PHP 中查找它？但这听起来也不正确，因为它开始处理 php 脚本并仅在 pdo 上堆叠，因此它连接到 php 容器，所以我不确定在哪里寻找问题

之前我为很多项目做了 docker setup，但是它们是用 PHP 框架编写的，例如 Laravel、Symfony，但是这个是一个手写项目，可能需要一些额外的更改？

更新

这是一个 php Docker 文件：

CMD ["php-fpm7", "-F"]

WORKDIR /var/www/vhosts/project

还有php -m 在启用的扩展列表中显示pdo_mysql

Answer 1

我做到了，所以如果在 docker 文件中我只有 RUN docker-php-ext-configure pdo_mysql && docker-php-ext-install mysqli pdo_mysql && docker-php-ext-enable pdo_mysql 它适用于 CLI，如果我只有 RUN apk add --update php7-pdo_mysql 它适用于 fpm 但不适用于 cli，所以我添加了两者，它适用于 cli 和每分钟。但这很奇怪，因为我正在使用我已经使用过很多次的锅炉编 docker confids，并且第一次遇到这个问题......
