实验目标
进行存储共享实验，使用nfs的技术方案进行跨namespace的存储共享
一、环境准备
- 单点k8s一套：192.168.XX.5
- nfs云主机一台：192.168.XX.62
- nfs目录：192.168.XX.62:/shared/
二、nfs环境的部署及连通性验证
nfs部署链接：https://blog.csdn.net/baidu_35848778/article/details/126933785
在k8s节点(192.168.XX.5)验证nfs-server的连通性
showmount -e 192.168.XX.62
# 输出
Export list for 192.168.XX.62:
/shared 192.168.XX.0/24
三、yaml文件的整理
1. pv文件
testpv1.yaml
apiVersion: v1
kind: PersistentVolume
metadata:name: nfs-pv1-namelabels:type: local
spec:storageClassName: nfs-pv1-sccapacity:storage: 10GiaccessModes:- ReadWriteManynfs:server: 192.168.XX.62path: /shared/
testpv2.yaml
apiVersion: v1
kind: PersistentVolume
metadata:name: nfs-pv2-namelabels:type: local
spec:storageClassName: nfs-pv2-sccapacity:storage: 10GiaccessModes:- ReadWriteManynfs:server: 192.168.XX.62path: /shared/
2.pvc文件
pv1-pvc1.yaml
kind: PersistentVolumeClaim
apiVersion: v1
metadata:name: pv1-pvc1namespace: default
spec:volumeName: nfs-pv1-nameaccessModes:- ReadWriteManyresources:requests:storage: 1GistorageClassName: nfs-pv1-sc
pv2-pvc1.yaml
kind: PersistentVolumeClaim
apiVersion: v1
metadata:name: pv2-pvc1namespace: slw-mariadb
spec:volumeName: nfs-pv2-nameaccessModes:- ReadWriteManyresources:requests:storage: 1GistorageClassName: nfs-pv2-sc
3.pod文件
pod1.yaml
apiVersion: v1
kind: Pod
metadata:name: minio-1namespace: default
spec:containers:- name: minioimage: minio:RELEASE.2022-12-07T00-56-37Zenv:- name: MINIO_ACCESS_KEYvalue: "admin"- name: MINIO_SECRET_KEYvalue: "admin123456"- name : TZvalue: Asia/Shanghaicommand:- /bin/bash- -cargs: - minio server /data --console-address :9090 --address :9000# add port for podports:- containerPort: 9090name: console-address- containerPort: 9000name: addressvolumeMounts:- name: minio-data-one mountPath: /data
#nodeSelector:# kubernetes.io/hostname: kubealpha.localvolumes:- name: minio-data-onepersistentVolumeClaim:claimName: pv1-pvc1
pod2.yaml
apiVersion: v1
kind: Pod
metadata:name: minio-2namespace: slw-mariadb
spec:containers:- name: minioimage: harbor.ictnj.ac.cn:10002/library/minio:RELEASE.2022-12-07T00-56-37Zenv:- name: MINIO_ACCESS_KEYvalue: "admin"- name: MINIO_SECRET_KEYvalue: "admin123456"- name : TZvalue: Asia/Shanghaicommand:- /bin/bash- -cargs: - minio server /data --console-address :9090 --address :9000# add port for podports:- containerPort: 9090name: console-address- containerPort: 9000name: addressvolumeMounts:- name: minio-data-one mountPath: /data
#nodeSelector:# kubernetes.io/hostname: kubealpha.localvolumes:- name: minio-data-onepersistentVolumeClaim:claimName: pv2-pvc1
四、创建资源
1.创建PV
root@node1:/home# kubectl create -f testpv1.yaml
persistentvolume/nfs-pv1-name created
root@node1:/home# kubectl create -f testpv2.yaml
persistentvolume/nfs-pv2-name created
root@node1:/home# kubectl get pv -A
NAME CAPACITY ACCESS MODES RECLAIM POLICY STATUS CLAIM STORAGECLASS REASON AGE
nfs-pv1-name 10Gi RWX Retain Available nfs-pv1-sc 6s
nfs-pv2-name 10Gi RWX Retain Available nfs-pv2-sc 3s
2.创建PVC
root@node1:/home# kubectl create -f pv1-pvc1.yaml
persistentvolumeclaim/pv1-pvc1 created
root@node1:/home# kubectl create -f pv2-pvc1.yaml
persistentvolumeclaim/pv2-pvc1 created
root@node1:/home# kubectl get pv -A
NAME CAPACITY ACCESS MODES RECLAIM POLICY STATUS CLAIM STORAGECLASS REASON AGE
nfs-pv1-name 10Gi RWX Retain Bound default/pv1-pvc1 nfs-pv1-sc 2m12s
nfs-pv2-name 10Gi RWX Retain Bound slw-mariadb/pv2-pvc1 nfs-pv2-sc 2m9s
3.创建pod
root@node1:/home# kubectl create -f pod1.yaml
pod/minio-1 created
root@node1:/home# kubectl create -f pod2.yaml
pod/minio-2 created
root@node1:/home# kubectl get pod -A |grep minio
default minio-1 1/1 Running 0 41s
slw-mariadb minio-2 1/1 Running 0 38s
五、进行文件创建实验
在pod1中创建文件，在pod2及nfs-client端检查是否可以看到文件
1.minio-1中创建测试文件
2.minio-2进行验证
3.nfs-client端验证
