本文介绍的动态生成NAS存储卷的方案在一个已有文件系统上自动生成一个目录这个目录定义为目标存储卷
镜像地址registry.cn-hangzhou.aliyuncs.com/acs/alicloud-nas-controller:v1.11.5.4-433631d-aliyun
默认生成资源 生成的PV名字为pvc-${pvc-uid} 生成目录的名字namespace-pvcname-pvname
可以再pvc的annotations中如下声明自定义名字 生成的pv、目录名字为下面定义的名字。 annotations:pv-name-created: replace-user-id
2. 部署NAS Controller
创建alicloud-nas-controller实现动态provider nas pv 创建alicloud-nas storageclass为nas pv provision 提供模板
apiVersion: storage.k8s.io/v1
kind: StorageClass
metadata:name: alicloud-nas
provisioner: alicloud/nas
reclaimPolicy: Delete
parameters:drivertype: flexvolumenfsversion: 4.0options: ---
kind: Deployment
apiVersion: extensions/v1beta1
metadata:name: alicloud-nas-controllernamespace: kube-system
spec:replicas: 1strategy:type: Recreatetemplate:metadata:labels:app: alicloud-nas-controllerspec:tolerations:- effect: NoScheduleoperator: Existskey: node-role.kubernetes.io/master- effect: NoScheduleoperator: Existskey: node.cloudprovider.kubernetes.io/uninitializedserviceAccount: admincontainers:- name: alicloud-nas-controllerimage: registry.cn-hangzhou.aliyuncs.com/acs/alicloud-nas-controller:v1.11.5.4-433631d-aliyunimagePullPolicy: AlwaysvolumeMounts:- mountPath: /persistentvolumesname: nfs-client-rootenv:- name: NFS_SERVERvalue: 154154b095-**.cn-beijing.nas.aliyuncs.com- name: NFS_PATHvalue: /volumes:- name: nfs-client-rootflexVolume:driver: alicloud/nasoptions:path: /server: 154154b095-**.cn-beijing.nas.aliyuncs.comvers: 4.0
StorageClass使用说明
drivertype: 用来表示生成pv存储类型可选nfs, flexvolume.nfs: 默认选项表示使用k8s原生NFS驱动挂载flexvolume: 表示使用阿里云提供的Flexvolume NAS驱动挂载nfsversion: 挂载nfs使用的版本支持34.0.默认为4.0drivertype为flexvolume的时候在这里配置为nfs的时候通过mountOptions 配置options为挂载nfs的可选项配置drivertype为flexvolume的时候在这里配置为nfs的时候通过mountOptions 配置
StorageClass举例
## 使用kubernetes提供的NFS驱动并配置mountOptionsreclaimPolicy为Delete
apiVersion: storage.k8s.io/v1
kind: StorageClass
metadata:name: alicloud-nas-nfs
mountOptions:
- vers4.0
- noresvport
provisioner: alicloud/nas
reclaimPolicy: Delete## 使用阿里云提供的Flexvolume NAS驱动配置nfs版本、options
apiVersion: storage.k8s.io/v1
kind: StorageClass
metadata:name: alicloud-nas-flex
provisioner: alicloud/nas
reclaimPolicy: Delete
parameters:drivertype: flexvolumenfsversion: 3options: noresvport
3. 创建应用-Deployment
kind: PersistentVolumeClaim
apiVersion: v1
metadata:name: replace-user-idannotations:pv-name-created: replace-user-id
spec:storageClassName: alicloud-nasaccessModes:- ReadWriteManyresources:requests:storage: 5Gi
---
apiVersion: extensions/v1beta1
kind: Deployment
metadata:name: deploy-nas
spec:replicas: 1strategy:type: Recreatetemplate:metadata:labels:app: deploy-nasspec:containers:- name: nginximage: nginxvolumeMounts:- name: pvc-nasmountPath: /datavolumes:- name: pvc-naspersistentVolumeClaim:claimName: replace-user-id执行
# userIDhello-123
# cat deploy.yaml | sed s/replace-user-id/\$userID\/g | kubectl create -f -# kubectl get pod | grep deploy-nas
deploy-nas-85696b6bfc-t5dmh 1/1 Running 0 28m# kubectl get pvc | grep hell
hello-123 Bound hello-123 5Gi RWX alicloud-nas-flex 28m# kubectl get pv | grep hell
hello-123 5Gi RWX Delete Bound default/hello-123 alicloud-nas-flex 28m# Nas目录下查看生成目录
# ls -l | grep hello
drwxrwxrwx 2 root root 4096 2月 19 09:58 hello-123
4. 创建应用-StatefulSet
使用volumeTemplateClaim不支持使用pv-name-created配置pv名字
apiVersion: v1
kind: Service
metadata:name: nginxlabels:app: nginx
spec:ports:- port: 80name: webclusterIP: Noneselector:app: nginx
---
apiVersion: apps/v1beta1
kind: StatefulSet
metadata:name: web
spec:replicas: 2serviceName: nginxtemplate:metadata:labels:app: nginxspec:containers:- name: nginximage: nginx:alpinevolumeMounts:- mountPath: /dataname: pvc-stsvolumeClaimTemplates:- metadata:name: pvc-stsspec:accessModes:- ReadWriteOncestorageClassName: alicloud-nas-flexresources:requests:storage: 2Gi创建后查看
# kubectl get pod | grep web
web-0 1/1 Running 0 7s
web-1 1/1 Running 0 4s# kubectl get pvc | grep web
pvc-sts-web-0 Bound pvc-65ab251a-33ec-11e9-a151-00163e066784 2Gi RWO alicloud-nas-flex 13m
pvc-sts-web-1 Bound pvc-8437c50e-33ed-11e9-a151-00163e066784 2Gi RWO alicloud-nas-flex 5m# kubectl get pv | grep web

pvc-8437c50e-33ed-11e9-a151-00163e066784 2Gi RWO Delete Bound default/pvc-sts-web-1 alicloud-nas-flex 5m# Nas目录下查看生成目录
# ls -l | grep sts
drwxrwxrwx 2 root root 4096 2月 19 10:16 default-pvc-sts-web-0-pvc-65ab251a-33ec-11e9-a151-00163e066784

5. 创建应用-Pod
kind: PersistentVolumeClaim
apiVersion: v1
metadata:name: replace-user-idannotations:pv-name-created: replace-user-id
spec:storageClassName: alicloud-nas-flexaccessModes:- ReadWriteManyresources:requests:storage: 5Gi
---
apiVersion: v1
kind: Pod
metadata:name: nas-pod
spec:containers:- name: nginximage: nginxvolumeMounts:- name: pvc-nasmountPath: /datavolumes:- name: pvc-naspersistentVolumeClaim:claimName: replace-user-id
# userIDpod-123
# cat pod.yaml | sed s/replace-user-id/\$userID\/g | kubectl create -f -# kubectl get pod | grep pod
nas-pod 1/1 Running 0 32s# kubectl get pvc | grep pod
pod-123 Bound pod-123 5Gi RWX alicloud-nas-flex 44s# kubectl get pv | grep pod
pod-123 5Gi RWX Delete Bound default/pod-123 alicloud-nas-flex 48s# ls -l | grep pod
drwxrwxrwx 2 root root 4096 2月 19 10:54 pod-123 原文链接 本文为云栖社区原创内容未经允许不得转载。
