【Kubernetes】k8s使用minio作为对象存储,Kubernetes,kubernetes,linux,容器

一、部署minio operator

k8s version：v1.20.15
minio version ：v4.4.16

（1）安装kubectl-minio插件

自选minio-operaterd的版本下载包

minio-operater plugin

# 上传服务器并解压
unzip kubectl-minio_linux_amd64.zip "kubectl-minio" -d /usr/local/bin/

# 查看是否安装成功。如返回版本信息则安装成功
kubectl minio version

# 初始化
kubectl minio init

# operator默认部署到minio-operator命名空间中，如果需要指定命名空间，可使用kubectl minio init --namespace {YOUR-NAMESPACE}。
# 使用群集。在配置operator的DNS主机名时，将本地作为群集域。指定kubectl minio init --cluster域参数以设置不同的集群域值。

# 验证是否安装成功
[root@k8s-master-4 ~]# kubectl get all -n minio-operator

二、创建StorageClass

1、sc-minio.yaml

apiVersion: storage.k8s.io/v1
kind: StorageClass
metadata:
   name: minio-local-storage     # SC-NAME
provisioner: kubernetes.io/no-provisioner
volumeBindingMode: WaitForFirstConsumer

创建

kubectl apply -f sc-minio.yaml

# 查看是否创建成功
[root@k8s-master-4 ~]# kubectl get sc
NAME                  PROVISIONER                    RECLAIMPOLICY   VOLUMEBINDINGMODE      ALLOWVOLUMEEXPANSION   AGE
minio-local-storage   kubernetes.io/no-provisioner   Retain          WaitForFirstConsumer   false                  5h38m

2、创建所需的永久卷

序号	路径	容量 (G)	说明	所在节点
1	/data/1	5	租户使用	3个节点各1个
2	/data/log1	5	租户使用	3个节点各1个
3	/data/minio-tenant-1-log-0	5	审计日志	k8s-master-4
4	/data/minio-tenant-1-prometheus	5	监控数据	k8s-master-4

租户：30G

# 创建目录(三个节点)
mkdir -p /data/1 /data/log1

# 在K8s-master-4创建审计日志目录、监控目录
mkdir -p /data/minio-tenant-1-log-0 /data/minio-tenant-1-prometheus

三、PV && PVC

为MinIO租户中的每个卷创建一个PV。例如，假设一个Kubernetes集群有3个节点，每个节点有2个本地连接的驱动器，那么总共创建6个本地PV。名称、容量大小、目录等可根据个人环境进行配置:

1、pv-tenant.yaml

四、创建MinIO Tenant租户

使用kubectl minio租户创建命令创建minio租户。该命令始终使用MinIO服务器和MinIO控制台的最新稳定Docker映像。

以下示例创建了一个3节点MinIO部署，6个驱动器的总容量为30Gi。此时会同时创建审计日志、prometheus监控相关pod。

# 查看minio支持的api-resource版本
[root@k8s-master-4 ~]# kubectl api-resources 
NAME             SHORTNAMES          APIVERSION                     NAMESPACED            KIND
......
tenants          tenant              minio.min.io/v2                true                  Tenant
......


[root@k8s-master-4 ~]# kubectl minio tenant create minio-tenant-1 \
>  --servers 3 \
>  --volumes 6  \
>  --capacity 30Gi \
>  --storage-class minio-local-storage \
>  --namespace minio-tenant-1

# 查看租户状态
# 当前状态在初始化过程中，等待Log Search就绪，此过程可能要花费一段时间，租户成功后，状态会显示Initialized：
[root@k8s-master-4 ~]# kubectl get tenants -n minio-tenant-1
NAME             STATE         AGE
minio-tenant-1   Initialized   19h

# 各pod、服务等对象成功状态
kubectl -n minio-tenant-1 get all

# 查看创建的pvc（如图二）
kubectl -n minio-tenant-1 get pvc

# 查看当前租户
[root@k8s-master-4 ~]# kubectl minio tenant list

Tenant 'minio-tenant-1', Namespace 'minio-tenant-1', Total capacity 30 GiB

  Current status: Initialized 
  MinIO version: minio/minio:RELEASE.2022-04-16T04-26-02Z 
  
  


# 可以使用kubectl端口转发程序临时公开每个服务。运行以下示例将流量从运行kubectl的主机转发到Kubernetes集群内运行的服务。
# 租户端口转发
[root@k8s-master-4 ~]# kubectl port-forward service/minio 443:443 -n minio-tenant-1 
Forwarding from 127.0.0.1:443 -> 9000
Forwarding from [::1]:443 -> 9000

[root@k8s-master-4 ~]# kubectl port-forward service/minio-tenant-1-console 9443:9443 -n minio-tenant-1 
Forwarding from 127.0.0.1:9443 -> 9443
