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

集群模式要求: 集群可以调度资源节点 >=4
集群资源不足时部署参考: https://www.cnblogs.com/vpc123/articles/14346984.html

资源创建过程:

# 创建StatefulSet
kubectl apply -f  minio-statefulset.yaml

# 创建service
kubectl apply -f minio-svc.yaml

# 创建ingress
kubectl apply -f minio-ingress.yaml

# 创建nodeport
kubectl apply -f minio-nodeport.yaml

Helm 改造
