一、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:

二、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
spec:containers:- name: minioimage: quay.io/minio/minio:latestcommand:- /bin/bash- -cargs: - minio server /data --console-address :9090volumeMounts:- mountPath: /dataname: localvolume # Corresponds to the `spec.volumes` Persistent VolumenodeSelector:kubernetes.io/hostname: kubealpha.local # Specify a node label associated to the Worker Node on which you want to deploy the pod.volumes:- name: localvolumehostPath: # MinIO generally recommends using locally-attached volumespath: /mnt/disk1/data # Specify a path to a local drive or volume on the Kubernetes worker nodetype: DirectoryOrCreate # The path to the last directory must exist

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

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。

三、步骤

3.1 创建资源

执行命令：kubectl apply -f minio.yaml

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:

可以看到控制台端口为5000,说明命令参数--console-address ":5000"生效。

3.2 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
