How to achieve permanent data deployment

[renshinijiuhao]

Here is the Kutt I deployed using Docker Composer. After running it, I added a few URLs, deleted the container, and recreated it. As a result, the previous data was lost. This is different from my other containers. After deploying my other containers, the data is still there. I want to know where the problem lies? How to solve it?

services:
  kutt:
    image: kutt/kutt:latest
    container_name: kutt
    restart: unless-stopped
    ports:
      - "3000:3000"
    environment:
      # 数据库配置 - 使用现有的 MariaDB
      DB_HOST: mariadb          # 或你的 MariaDB 容器 IP/主机名
      DB_PORT: 3306
      DB_NAME: kutt             # 确保 MariaDB 中已创建此数据库
      DB_USER: kutt             # 替换为你的 MariaDB 用户名
      DB_PASSWORD: kutt12356789 # 替换为你的 MariaDB 密码
      
      # Redis 配置 - 使用现有的 Redis
      REDIS_HOST: redis         # 或你的 Redis 容器 IP/主机名
      REDIS_PORT: 6379
      REDIS_PASSWORD:  # 如果没有密码，留空或删除
      
      # Kutt 应用配置
      SITE_NAME: Kutt
      DEFAULT_DOMAIN: kutt.sua1.tk  # 替换为你的域名
      JWT_SECRET: sua111020  # 生成随机字符串
      MAIL_HOST: smtp.qq.com             # 如需邮件功能，配置 SMTP
      MAIL_PORT: 465
      MAIL_USER: 4765@qq.com
      MAIL_PASS: hylssqhjdfhjiwqcb
      MAIL_FROM: 4765@qq.com
      DISALLOW_REGISTRATION: "false"
      DISALLOW_ANONYMOUS_LINKS: "false"
    volumes:
      - ./custom:/kutt/custom
      # 持久化上传的文件（如自定义短链图标等）
      - ./data/uploads:/usr/src/app/uploads
      
      # 持久化日志
      - ./data/logs:/usr/src/app/logs
    networks:
      mynet:
        ipv4_address: 172.21.0.8

networks:
  mynet:
    external: true              # 使用已存在的外部网络​
