# MinIO Object Storage - Docker Compose
# =============================================================================
#
# MinIO 是一个高性能的分布式对象存储系统，兼容 Amazon S3 API
#
# 用途:
#   - 用户头像存储
#   - 用户文档存储
#   - 应用资源文件存储
#   - 备份文件存储
#
# 使用方法:
#   ./deploy.sh up          # 启动 MinIO
#   ./deploy.sh down        # 停止 MinIO
#   ./deploy.sh status      # 查看状态
#   ./deploy.sh logs        # 查看日志
#   ./deploy.sh create-bucket <name>  # 创建存储桶
#
# 访问地址:
#   API:     http://localhost:9000
#   Console: http://localhost:9001
