使用sidekick 负载均衡minio 集群
实际上对于minio集群的lb+proxy 官方的cookbook 有解决（nginx，caddy)但是最近官方提供了一个新的基于
sidecar模式的选择-sidekick 以下是minio 集群集成sidekick 的试用
环境准备
整个环境都是基于docker运行
*docker-compose 文件

- 说明
minio 集群的部署，参考官方文档，使用了4个节点8块盘的模式，同时使用sidecar sidecar 模式代理4个minio 节点
默认minio集群没有开启browwer ui 通过gateway 模式提供，对于数据的访问通过sidekick暴露的80 端口 - 启动
docker-compose up -d
使用
- 创建bucket 以及上传文件
如下 
- 访问页面
访问地址：http://localhost/apps/index.html 
说明
使用sidekick给予我们使用minio以及稳定可靠的访问minio提供了新的方式，目前看到官方也在计划支持s3 兼容的cache，还是比较期待的,如果查看
了sidekick源码的话，sidekick 没有多少比较复杂的东西，可以学习下
