Docker 連接nginx/php/mysql的問題

Question

我正在嘗試為本地環境的一些 PHP 項目設置 docker。 我創建了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

也可能我需要為一個項目共享 nginx 虛擬主機（我從臨時服務器獲取了這個虛擬主機配置，也許它需要更多更改？）

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;

    }
}

所以問題是我收到錯誤Uncaught PDOException: could not find a driver in當我試圖從瀏覽器訪問該站點時，但是當我，例如，從工作空間或worksapce容器運行遷移時， php都在工作正確。

I'm assuming that for some reason nginx container is not linked with php container and trying to find the pdo driver inside of the nginx container instead of looking it in the PHP ? 但這聽起來也不正確，因為它開始處理 php 腳本並僅在 pdo 上堆疊，因此它連接到php容器，所以我不確定在哪里尋找問題

Previously I have made docker setup for many projects but they was written with PHP frameworks like Laravel , Symfony , but this one is a handwritten project and maybe it requires some additional changes?

更新

這是一個 php Docker 文件：

php -m在啟用的擴展列表中顯示pdo_mysql

Answer 1

我做到了，所以如果在 docker 文件中我只有RUN apk add --update php7-pdo_mysql docker RUN docker-php-ext-configure pdo_mysql && docker-php-ext-install mysqli pdo_mysql && docker-php-ext-enable pdo_mysql它只適用於 CLI，如果我有RUN apk add --update php7-pdo_mysql它適用於 fpm 但不適用於 cli，所以我添加了兩者，它適用於 cli 和 fpm。 但這很奇怪，因為我使用的是鍋爐辮子 docker 我已經使用過很多次了，而且第一次遇到這個問題......
