NFS动态制备
1. 拉取代码
从github上拉取代码，这一步会因为网络原因造成失败，多试几次就好
[root@master ~]# git clone https://github.com/kubernetes-csi/csi-driver-nfs.git [root@master ~]# cd csi-driver-nfs/
2. 修改镜像仓库为阿里云
[root@master csi-driver-nfs]# cp -a deploy/v4.6.0/ deploy/v4.6.0-bak [root@master csi-driver-nfs]# sed -i 's@registry.k8s.io/sig-storage@registry.aliyuncs.com/google_containers@g' deploy/v4.6.0/*.yaml
2.1 拉取镜像
因为有一个镜像阿里云里面好像没有，需要从别的地方拉取，拉取完了之后我们将镜像的tag改为阿里云的，这样就不需要去改动yaml文件了
[root@master csi-driver-nfs]# docker pull registry.cn-hangzhou.aliyuncs.com/image-storage/nfspluginnfsplugin:v4.6.0 [root@master csi-driver-nfs]# docker tag registry.cn-hangzhou.aliyuncs.com/image-storage/nfspluginnfsplugin:v4.6.0 registry.aliyuncs.com/google_containers/nfsplugin:v4.6.0
3. 开始安装csi
[root@master csi-driver-nfs]# ./deploy/install-driver.sh v4.6.0 local
4. 查看pod状态
[root@master csi-driver-nfs]# kubectl get pods -n kube-system |grep nfs csi-nfs-controller-6666d547dc-scpvc 4/4 Running 0 15s csi-nfs-node-p4bk7 3/3 Running 0 15s
当2个pod都running之后我们去创建sc
5. 创建sc
[root@master csi-driver-nfs]# cd deploy/example/ [root@master example]# ls cloning fsgroup nginx-pod-nfs.yaml pv-nfs-csi.yaml statefulset.yaml daemonset-nfs-ephemeral.yaml nfs-provisioner pvc-nfs-csi-dynamic.yaml README.md storageclass-nfs.yaml deployment.yaml nginx-pod-inline-volume.yaml pvc-nfs-csi-static.yaml snapshot
5.1 修改storageclass-nfs.yaml
[root@master example]# cat storageclass-nfs.yaml --- apiVersion: storage.k8s.io/v1 kind: StorageClass metadata: name: nfs-csi provisioner: nfs.csi.k8s.io parameters: server: 192.168.0.10 share: /nfs # csi.storage.k8s.io/provisioner-secret is only needed for providing mountOptions in DeleteVolume # csi.storage.k8s.io/provisioner-secret-name: "mount-options" # csi.storage.k8s.io/provisioner-secret-namespace: "default" reclaimPolicy: Delete volumeBindingMode: Immediate mountOptions: - nfsvers=4.1
- 将server 改为nfs服务器的地址
- 将share 改为nfs共享的目录
[root@master example]# kubectl apply -f storageclass-nfs.yaml [root@master example]# kubectl get sc NAME PROVISIONER RECLAIMPOLICY VOLUMEBINDINGMODE ALLOWVOLUMEEXPANSION AGE csi-rbd-sc rbd.csi.ceph.com Delete Immediate true 3d6h nfs-csi nfs.csi.k8s.io Delete Immediate false 16s
然后就会有一个nfs-csi的sc了
6. 将sc设为默认
[root@master example]# kubectl edit sc nfs-csi apiVersion: storage.k8s.io/v1 kind: StorageClass metadata: annotations: storageclass.kubernetes.io/is-default-class: "true" kubectl.kubernetes.io/last-applied-configuration: | {"apiVersion":"storage.k8s.io/v1","kind":"StorageClass","metadata":{"annotations":{},"name":"nfs-csi"},"mountOptions":["nfsvers=4.1"],"parameters":{"server":"192.168.0.10","share":"/nfs"},"provisioner":"nfs.csi.k8s.io","reclaimPolicy":"Delete","volumeBindingMode":"Immediate"} creationTimestamp: "2024-06-26T08:22:50Z"
在注释里面加入storageclass.kubernetes.io/is-default-class: "true"
[root@master example]# kubectl get sc NAME PROVISIONER RECLAIMPOLICY VOLUMEBINDINGMODE ALLOWVOLUMEEXPANSION AGE csi-rbd-sc rbd.csi.ceph.com Delete Immediate true 3d6h nfs-csi (default) nfs.csi.k8s.io Delete Immediate false 50s
然后他的后面就会出现一个default
7. 测试使用
编写一个pvc的yaml文件
apiVersion: v1 kind: PersistentVolumeClaim metadata: name: sc-pvc spec: accessModes: - ReadWriteOnce volumeMode: Filesystem resources: requests: storage: 20Gi
[root@master euler]# kubectl apply -f pvc-test.yaml persistentvolumeclaim/sc-pvc created [root@master euler]# kubectl get pvc NAME STATUS VOLUME CAPACITY ACCESS MODES STORAGECLASS AGE sc-pvc Bound pvc-8f3ce5f8-79a6-40a7-82e3-a1a6d894d3c3 20Gi RWO nfs-csi 3s
