k8s-对接NFS存储

一、前提条件

1、NFS_Server 部署好了。

2、网络可达。

二、 使用方式

1、CSI

**项目地址

github /kubernetes-csi/csi-driver-nfs#readme

Install NFS CSI driver v4.10.0 version on a kubernetes cluster

If you have already installed Helm, you can also use it to install this driver. Please check Installation with Helm.

Install with kubectl

*下面两种方式选一个。

Option#1. remote install curl -skSL raw.githubusercontent /kubernetes-csi/csi-driver-nfs/v4.10.0/deploy/install-driver.sh | bash -s v4.10.0 -- Option#2. local install git clone github /kubernetes-csi/csi-driver-nfs.git cd csi-driver-nfs ./deploy/install-driver.sh v4.10.0 local check pods status: kubectl -n kube-system get pod -o wide -l app=csi-nfs-controller kubectl -n kube-system get pod -o wide -l app=csi-nfs-node

example output:

NAME READY STATUS RESTARTS AGE IP NODE csi-nfs-controller-56bfddd689-dh5tk 4/4 Running 0 35s 10.240.0.19 k8s-agentpool-22533604-0 csi-nfs-node-cvgbs 3/3 Running 0 35s 10.240.0.35 k8s-agentpool-22533604-1 csi-nfs-node-dr4s4 3/3 Running 0 35s 10.240.0.4 k8s-agentpool-22533604-0 clean up NFS CSI driver

Option#1. remote uninstall curl -skSL raw.githubusercontent /kubernetes-csi/csi-driver-nfs/v4.10.0/deploy/uninstall-driver.sh | bash -s v4.10.0 -- Option#2. local uninstall git clone github /kubernetes-csi/csi-driver-nfs.git cd csi-driver-nfs git checkout v4.10.0 ./deploy/uninstall-driver.sh v4.10.0 local

2、手动——PV_PVC

apiVersion: v1 kind: PersistentVolume metadata:   name: nfs spec:   capacity:     storage: 1Mi   accessModes:     - ReadWriteMany   nfs:     server: nfs-server.default.svc.cluster.local     path: "/"   mountOptions:     - nfsvers=4.2 --- apiVersion: v1 kind: PersistentVolumeClaim metadata:   name: nfs spec:   accessModes:     - ReadWriteMany   storageClassName: ""   resources:     requests:       storage: 1Mi   volumeName: nfs

3、POD直接读取

apiVersion: v1 kind: Pod metadata: name: test-pd spec: containers: - image: registry.k8s.io/test-webserver name: test-container volumeMounts: - mountPath: /my-nfs-data name: test-volume volumes: - name: test-volume nfs: server: my-nfs-server.example path: /my-nfs-volume readOnly: true
