原理及架构网上有很多总结很好的，这里就不分享了，有需要的可以上网查一下

kuberntes集群环境

使用外包精通--0成本学习IT运维kubespray--master高可用方案部署的k8s测试环境

[root@node1 minio]# kubectl get no -o wide
NAME    STATUS   ROLES           AGE   VERSION   INTERNAL-IP     EXTERNAL-IP   OS-IMAGE          KERNEL-VERSION          CONTAINER-RUNTIME
node1   Ready    control-plane   23h   v1.28.6   192.168.2.129   <none>        CentOS Stream 9   5.14.0-435.el9.x86_64   docker://20.10.20
node2   Ready    control-plane   23h   v1.28.6   192.168.2.158   <none>        CentOS Stream 9   5.14.0-435.el9.x86_64   docker://20.10.20
node3   Ready    <none>          23h   v1.28.6   192.168.2.234   <none>        CentOS Stream 9   5.14.0-435.el9.x86_64   docker://20.10.20
[root@node1 minio]#

参考文档

官方网站：https://min.io/

Github地址：https://github.com/minio/minio

部署参考链接：https://min.io/docs/minio/kubernetes/upstream/index.html

setup一：下载MinIO对象

下载MinIO-dev.yaml到k8s集群master机器上

curl https://raw.githubusercontent.com/minio/docs/master/source/extra/examples/minio-dev.yaml -O

setup二：修改MInIOn.yaml配置

修改节点选择器，根据开发需求进行修改
修改path路径
到对应的节点上创建路径

节点选择器查看

[root@node1 ~]# kubectl get nodes --show-labels
NAME    STATUS   ROLES           AGE   VERSION   LABELS
node1   Ready    control-plane   18h   v1.28.6   beta.kubernetes.io/arch=amd64,beta.kubernetes.io/os=linux,kubernetes.io/arch=amd64,kubernetes.io/hostname=node1,kubernetes.io/os=linux,node-role.kubernetes.io/control-plane=,node.kubernetes.io/exclude-from-external-load-balancers=
node2   Ready    control-plane   18h   v1.28.6   beta.kubernetes.io/arch=amd64,beta.kubernetes.io/os=linux,kubernetes.io/arch=amd64,kubernetes.io/hostname=node2,kubernetes.io/os=linux,node-role.kubernetes.io/control-plane=,node.kubernetes.io/exclude-from-external-load-balancers=
node3   Ready    <none>          18h   v1.28.6   beta.kubernetes.io/arch=amd64,beta.kubernetes.io/os=linux,kubernetes.io/arch=amd64,kubernetes.io/hostname=node3,kubernetes.io/os=linux
[root@node1 ~]#

修改path路径

测试选择了node3，并且在node3上创建了data路径

[root@node1 minio]# ssh node3
Activate the web console with: systemctl enable --now cockpit.socket

Last login: Thu Apr 25 11:51:59 2024 from 192.168.2.129

[root@node3 ~]# mkdir /data

setup三：使用命令部署minio-dev.yaml：kubectl apply -f minio-dev.yaml

[root@node1 minio]# kubectl apply -f minio-dev.yaml
namespace/minio-dev created
pod/minio created
[root@node1 minio]#

Get Pod

[root@node1 minio]# kubectl get pod -n minio-dev
NAME    READY   STATUS    RESTARTS   AGE
minio   1/1     Running   0          4h1m
[root@node1 minio]#

MinIO logs

[root@node1 minio]# kubectl logs pod/minio -n minio-dev
Formatting 1st pool, 1 set(s), 1 drives per set.

描述

Setup四：端口转发及浏览器访问

使用port-forward转发端口

[root@node1 minio]# kubectl port-forward --address 0.0.0.0 pod/minio 9000 9090 -n minio-dev
Forwarding from 0.0.0.0:9000 -> 9000
Forwarding from 0.0.0.0:9090 -> 9090
Handling connection for 9090
