一、k8s部署minio

1.1说明

项目使用minio，准备在k8s环境部署一套minio试用。

1.关于minio的原理和概念参考:

1.2 yaml内容

参考:
https://www.jianshu.com/p/2d45990dd652

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

# Deploys a new Namespace for the MinIO Pod
apiVersion: v1
kind: Namespace
metadata:name: minio-dev # Change this value if you want a different namespace namelabels:name: minio-dev # Change this value to match metadata.name
---
# Deploys a new MinIO Pod into the metadata.namespace Kubernetes namespace
#
# The `spec.containers[0].args` contains the command run on the pod
# The `/data` directory corresponds to the `spec.containers[0].volumeMounts[0].mountPath`
# That mount path corresponds to a Kubernetes HostPath which binds `/data` to a local drive or volume on the worker node where the pod runs
# 
apiVersion: v1
kind: Pod
metadata:labels:app: minioname: minionamespace: minio-dev # Change this value to match the namespace metadata.name

---

实际使用到的minio.yaml配置文件:

apiVersion: v1
kind: PersistentVolume
metadata:labels:app: miniorelease: minioname: minionamespace: sscs-dev
spec:accessModes:- ReadWriteOncecapacity:storage: 10GivolumeMode: FilesystemhostPath:path: /home/cicd/sscs-dev/minio
---
apiVersion: v1
kind: PersistentVolumeClaim
metadata:# This name uniquely identifies the PVC. Will be used in deployment below.name: minio-pv-claimlabels:app: minio-storage-claimnamespace: sscs-dev
spec:# Read more about access modes here: https://kubernetes.io/docs/user-guide/persistent-volumes/#access-modesaccessModes:- ReadWriteOnceresources:# This is the request for storage.

apiVersion: apps/v1
kind: Deployment

---
apiVersion: v1
kind: Service
metadata:namespace: sscs-devname: minio-servicespec:type: NodePortports:- name: dataport: 9000targetPort: 9000protocol: TCPnodePort: 31955- name: consoleport: 5000targetPort: 5000protocol: TCPnodePort: 32108selector:app: minio

注意事项：
要添加--console-address ":5000"命令参数来固定控制台端口，否则页面会无法访问。

1.3 步骤

1.3.1 创建资源

执行命令：kubectl apply -f minio.yaml

1.3.2 查看启动日志

kubectl get pod -n sscs-dev | grep minio查看pod运行状态,正常:

kubectl logs -f minio-deployment-54648b586-kxcbn -n sscs-dev查看pod运行日志:

根据日志可获取以下信息:

1. api端口为9000,控制台端口为5000
2. 控制台端口为5000,说明命令参数--console-address ":5000"生效。

1.3.3 查看svc并访问控制台

执行命令:kubectl get svc -n sscs-dev | grep minio

yaml中使用的svc是nodePort类型，可以看到以上控制台5000端口映射主机32108端口,则访问地址为: 服务器ip:32108：

出现以上页面表示成功

二、docker部署minio-client

参考文章:
https://blog.csdn.net/weixin_45821811/article/details/119116172

2.1 查找镜像

执行命令docker search minio/mc

2.2 运行镜像

执行命令: docker run -it --entrypoint=/bin/sh minio/mc
参数说明:
-i: 以交互模式运行容器，通常与 -t 同时使用；
-t: 为容器重新分配一个伪输入终端，通常与 -i 同时使用；

注意：
启动容器时要加上参数：-it --entrypoint=/bin/sh，启动后自动进入容器终端，否则容器一启动就会退出。

2.3 绑定minio server

1. 执行完容器启动命令: docker run -it --entrypoint=/bin/sh minio/mc之后，会自动进入容器终端。
2. 此时在容器内部执行命令绑定minio server: mc config host add minio http://132.1xx.xx.5:31955

说明：
mc config host add minio http://132.1xx.xx.5:31955
minio 为别名，可自定义
http://132.1xx.xx.5:31955 为minio服务部署的ip和api映射的主机端口，1.3.3 中可查看api端口9000映射的主机端口

3. 命令行会要求输入access key和secret key（参考minio.yaml中配置的值）
   
   至此minio-client部署完成，可以使用相关命令来直接操作minio server
