Docker 部署 Minio 集群

Backgroud

Minio 有单节点、集群两种部署方式

单节点多硬盘利用数据冗余实现数据可靠性，但单节点不具备高可用

集群一般推荐至少 4 节点 + 4 硬盘，即每节点 1 块硬盘，最多支持两节点故障

Docker Compose 部署

在单机上启 4 个 Minio 容器模拟多节点部署

http://minio{1...4}:9000/data 中 minio{1...4} 表示 4 个节点的 hostname，/data 表示磁盘

每个节点有多块磁盘时，可以使用 /data{1...2}

启动容器，登录任意一个节点的 console-address

docker compose up -d

进入 Monitoring 查看节点和磁盘状态
