Codeigniter 3 Docker 编写设置

Question

我目前正在我的计算机上使用 WAMP，但我想转到 docker 以使 Codeigniter 应用程序的设置更容易。我正在使用已设置为使用 HMVC 模型的 CodeIgniter 3。在 docker 设置中，我可以从浏览器访问整个应用程序的索引页面，但我从 Codeigniter 的内部系统文件中得到了几个错误。

这是我遇到的错误：

这是我的会话配置变量：

$config['sess_driver'] = 'files';
$config['sess_cookie_name'] = 'ci_session';
$config['sess_expiration'] = 7200;
$config['sess_save_path'] = NULL;
$config['sess_match_ip'] = FALSE;
$config['sess_time_to_update'] = 300;
$config['sess_regenerate_destroy'] = FALSE;

如果可能的话，我宁愿不必将任何会话信息保存到文件中。在 WAMP 中工作时，此配置工作正常。

这是我的 docker 撰写文件：

version: '3'
services:
  apache:
    image: php:7.0-apache
    hostname: apache
    ports:
    - "80:80" # normal php port for trafic and functionality
    volumes:
      - ./app:/var/www/html

  mysql:
    image: mysql:8.0
    hostname: mysql
    ports:
      - "3306:3306" # mysql connection port
    environment:
      MYSQL_USER_FILE: var/lib/mysql-user
      MYSQL_PASSWORD_FILE: var/lib/mysql-user-p
      MYSQL_DATABASE_FILE: var/lib/mysql-db
      MYSQL_ROOT_PASSWORD_FILE: var/lib/mysql-root-p
    volumes:
      - ./data:/var/lib/

  phpmyadmin:
    image: phpmyadmin/phpmyadmin:latest
    restart: always
    links:
      - mysql
    ports:
      - "8183:80" # phpmyadmin login page
    environment:
      PMA_USER: user
      PMA_PASSWORD: password
      PMA_ARBITRARY: 1

-app：包含 codeigniter 文件

-data：包含用于放置 mysql 数据和一些配置文件的文件夹。

感谢您的帮助！

按照 ED 先生的建议，我修复了 problem:I 没有将会话字段留空并决定使用数据库来存储数据。
