背景概况
MinIO 是全球领先的对象存储先锋，以 Apache License v2.0 发布的对象存储服务器，是为云应用和虚拟机而设计的分布式对象存储服务器。在标准硬件上，读/写速度上高达183GB/s和171GB/s。它与 Amazon S3 云存储服务兼容。 它最适用于存储非结构化数据，如照片、视频、日志文件、备份和容器/虚拟机映像。 对象的大小可以从几KB 到最大5TB。
- 对象存储，兼容Amazon S3协议
- 安装运维相对简单，开箱即用
- 后端除了本地文件系统，还支持多种存储系统，目前已经包括 OSS
- 原生支持bucket事件通知机制
- 可通过多节点集群方式，支持一定的高可用和数据容灾
- 有WEB管理界面和CLI，可以用于测试或者管理
- 公开bucket中的数据可以直接通过HTTP获取

本次改造的 minio 是单实例节点副本的 helm 化改造，主要用于机器资源不足，没有进行全盘虚拟化的场景下的资源调度管理上的应用部署，针对应用的场景不同，所以需要结合不同的项目需求进行设计。minio 可以支持单实例副本，同时也支持最小的四节点集群模式（所以在资源较少时建议采用单副本的minio,在集群中可以调度的机器节点资源大于等于4时，minio的集群模式才可以正常使用，后续将会开展集群模式的改造部署）
