K3s 集群 helm 化改造之集群 minio

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

资源改造目录如下:

[root@vm3290 helm]# tree minio-distributed/
minio-distributed/
├── Chart.yaml
├── README.md
├── templates
│   ├── minio-ingress.yaml
│   ├── minio-nodeport.yaml
│   ├── minio-statefulset.yaml
│   ├── minio-svc.yaml
│   ├── NOTES.txt
│   └── tests
│       └── test-connection.yaml
└── values.yaml

2 directories, 9 files

定义 values.yaml 内容如下:

replicas: 4
strategy: Recreate
resources:
  limits:
    cpu: "1"
    memory: 1Gi
  requests:
    cpu: 200m
    memory: 200Mi

pv:
  accessModes: ReadWriteOnce
  storage: 5Gi

service:
  name: minio-service
  nodeport: minio-node

ingress:
  name: minio-ingress
  host: traefik.minio-distributed.io

# 请不要轻易修改此配置
global:
  namespace: minio-ss
  minio:
    name: minio-ss
    image: minio/minio
    tag: latest
    port: 9000
