Loki 日志系统分布式部署实践四 minio
说明
loki 支持文件系统、对象存储、NoSQL,对象存储大多都要使用公有云,但所幸的是它支持了 aws s3 兼容的存储,那么这里就可以使用 ceph rgw 和 minio,本篇部署 minio
说明
对象存储在云环境下是一种基础设施,在大数据、AI领域可以将它作为基本的存储方式。Spark、TensorFlow 都可以使用对象存储,它也可以作为 HDFS 的代替者。
minio 出品自一个有着多年网络文件系统开发经验的团队,其初始创始团队都来自于原 Glusterfs 团队,该团队二次创业的产品 minio 的设计广泛吸取了 glusterfs 的经验和教训:
MinIO 是一个开源的对象存储解决方案,特点包括:
- 高性能: 作为高性能对象存储,在标准硬件条件下它能达到 55GB/s 的读、35GG/s 的写速率
- 可扩容: 不同 MinIO 集群可以组成联邦,并形成一个全局的命名空间,并跨越多个数据中心,可按 zone 扩展(原 zone 不受任何影响),支持单个对象最大 5TB;
- 云原生: 容器化、基于 K8S 的编排、多租户支持
- 兼容性: 兼容 S3 API 这一事实上的对象存储标准,最先支持 S3 Select
- 简单: 这一设计原则让 MinIO 不容易出错、更快启动。一个 single 二进制文件即是一切,还可支持各种平台。(托了 go 语言的福)
-
支持纠删码: MinIO 使用纠删码(不是副本机制)、Checksum 来防止硬件错误和静默数据污染(Bit Rot,在没有任何信号的情况下磁盘发生数据错误)。在最高冗余度配置下,即使丢失 1/2 的磁盘也能恢复数据。低冗余且磁盘损坏高容忍,标准且最高的数据冗余系数为 2(即存储一个 1M 的数据对象,实际占用磁盘空间为 2M)。但在任意 n/2 块 disk 损坏的情况下依然可以读出数据(n 为一个纠删码集合(Erasure Coding Set)中的 disk 数量)。并且这种损坏恢复是基于单个对象的,而不是基于整个存储卷的。

安装
通过 minio-operator 安装:
注意:这里作为一个 kubectl 插件来使用了
下载包:
# wget https://github.com/minio/operator/releases/download/v3.0.28/kubectl-minio_3.0.28_linux_amd64
# mv kubectl-minio_3.0.28_linux_amd64 /usr/local/bin/kubectl-minio
# chmod +x /usr/local/bin/kubectl-minio
# kubectl plugin list
The following compatible plugins are available:
/usr/local/bin/kubectl-minio
查看帮助:
# kubectl minio
kubectl plugin to manage MinIO operator CRDs.
Usage:
minio [command]
Available Commands:
delete Delete MinIO Operator deployment
help Help about any command
init Initialize MinIO Operator deployment
tenant Manage MinIO tenant
Flags:
-h, --help help for minio
Use "minio [command] --help" for more information about a command.
安装 minio-operator
注意:可以使用 -o(不是 -o yaml)导出 minio-operator 的 yaml 进行手工修改部署(但是不全,缺少了 apiVersion、kind 等字段)
# kubectl create ns minio
# kubectl minio init --namespace minio --image harbor.sit.hupu.io/k8s/k8s-operator:v3.0.28
CustomResourceDefinition tenants.minio.min.io: created

minio 支持多种 server 启动模式
- standalone mode 单节点单盘
# minio server data
- standalone mode 单节点 4 盘纠删码
# minio server data1 data2 data3 data4
minio server 启动支持语法糖 - 省略号语法:
# minio server data{1...4}
- distributed mode 多节点纠删码(每节点 4 盘)
在 distributed mode 下,minio server 后面的远程的 endpoint 采用 http url 编码格式:
# export MINIO_ACCESS_KEY=<ACCESS_KEY>
# export MINIO_SECRET_KEY=<SECRET_KEY>
# minio server http://host{1...4}:9000/minio/data{1...4}
通过 tenants CR 资源创建 minio 集群:
注意:tenant 是由运营商创建和管理的 MinIO 集群。在创建 tenant 之前,请确保已安装必要的节点和驱动器,并且已创建相关的 PV 或默认的非跨可用区的 storageclass。
# kubectl get sc
NAME PROVISIONER RECLAIMPOLICY VOLUMEBINDINGMODE ALLOWVOLUMEEXPANSION AGE
alicloud-disk-efficiency (default) diskplugin.csi.alibabacloud.com Delete Immediate true 59d
alicloud-disk-ssd diskplugin.csi.alibabacloud.com Delete Immediate true 59d
要求 MinIO-Operator 创建一个具有 4 节点,总计 16 个卷和 480Gi 总原始容量(每个节点有 4 个 30 Gi 的卷)的 minio 集群:
注意:分布式 Minio 至少需要 4 个节点,使用分布式 Minio 就自动引入了纠删码功能。
注意:这里会返回 Access Key 和 Secret Key
# kubectl minio tenant create --name tenant1 --servers 4 --volumes 16 --capacity 480Gi --namespace minio
