Docker部署Directus时数据库与上传目录写入权限异常排查

问题背景 #

在全新安装的Ubuntu服务器上，以root用户运行Docker部署Directus，本地创建目录并运行Docker无异常，但将目录复制到服务器后出现数据库文件和上传目录无法写入的问题。

docker-compose配置 #

version: "3"
services:
  directus:
    image: directus/directus:latest
    ports:
      - 8055:8055
    volumes:
      - ./database:/directus/database
      - ./uploads:/directus/uploads
      - ./extensions:/directus/extensions
    environment:
      SECRET: "itsasecret"
      ADMIN_EMAIL: "user"
      ADMIN_PASSWORD: "passw"
      DB_CLIENT: "sqlite3"
      DB_FILENAME: "/directus/database/data.db"
      WEBSOCKETS_ENABLED: "true"

已尝试的操作 #

• 将root用户加入docker组，执行命令：

  sudo groupadd docker
  sudo usermod -aG docker $USER
  

  组信息验证结果：

  grep 'docker' /etc/group 
  docker:x:987:root
  

• 尝试将数据库和上传目录权限改为777（仅测试用，登录恢复正常但上传仍报错）
• 尝试将目录权限改为755，问题依旧

请问我哪里操作有误？
