阿里云 K8S 通过 pv 和 pvc 静态挂载已有的 NAS 目录

一、创建和获取阿里云的挂载点，不了解的可以看阿里云帮助文档

找台机器把目录挂载上去，上传需要容器需要使用的文件 yum install -y nfs-utils mount -t nfs -o vers=3,nolock,proto=tcp,rsize=1048576,wsize=1048576,hard,timeo=600,retrans=2,noresvport 88888888-ney35.cn-shenzhen.nas.aliyuncs.com:/ /mnt # 创建对应的目录, 注意创建的目录要与 PV 的路径一样 cd /mnt mkdir gc-wms2 cd gc-wms2 mkdir dir1 dir2 touch dir1/hello.txt touch dir2/world.txt tree ./ ./ ├── dir1 │ └── hello.txt └── dir2 └── world.txt # umount cd ~ && umount /mnt 三、创建 PV 和 PVC cat gc_wms_nas2.yaml apiVersion: v1 kind: PersistentVolume metadata: name: gc-wms-pv-nas namespace: devops labels: alicloud-pvname: gc-wms-pv-nas spec: capacity: storage: 10Mi accessModes: - ReadWriteMany csi: driver: nasplugin.csi.alibabacloud.com volumeHandle: gc-wms-pv-nas volumeAttributes: server: "88888888-ney35.cn-shenzhen.nas.aliyuncs.com" # 指定挂载点 path: "/gc-wms2" # 与第二部分在 nas 创建的目录一致 mountOptions: - nolock,tcp,noresvport - vers=3 --- kind: PersistentVolumeClaim apiVersion: v1 metadata: name: gc-wms-pvc-nas namespace: devops spec: accessModes: - ReadWriteMany resources: requests: storage: 10Mi selector: matchLabels: alicloud-pvname: gc-wms-pv-nas # 创建 kubectl apply -f gc_wms_nas2.yaml 四、创建应用 cat test.yaml apiVersion: apps/v1 kind: Deployment metadata: name: nginx-nas namespace: devops labels: app: klvchen-nginx spec: selector: matchLabels: app: klvchen-nginx template: metadata: labels: app: klvchen-nginx spec: containers: - name: klvchen-nginx image: nginx:1.7.9 ports: - containerPort: 80 volumeMounts: - name: pv-nas mountPath: "/data1" subPath: "dir1" # 指定挂载 nas 中 /gc-wms2/dir1 文件夹 - name: pv-nas mountPath: "/data2" subPath: "dir2" # 指定挂载 nas 中 /gc-wms2/dir2 文件夹 volumes: - name: pv-nas persistentVolumeClaim: claimName: gc-wms-pvc-nas # 指定上面 PVC 的名字 # 启动 kubectl apply -f test.yaml 五、测试 kubectl get pods -n devops NAME READY STATUS RESTARTS AGE nginx-nas-69f5fd8f78-phfs4 1/1 Running 0 7s kubectl -n devops exec -it nginx-nas-69f5fd8f78-phfs4 /bin/bash # 测试成功 root@nginx-nas-69f5fd8f78-phfs4:/# cd data1/ root@nginx-nas-69f5fd8f78-phfs4:/data1# ls hello.txt root@nginx-nas-69f5fd8f78-phfs4:/data1# cd .. root@nginx-nas-69f5fd8f78-phfs4:/# cd data2/ root@nginx-nas-69f5fd8f78-phfs4:/data2# ls world.txt |
例如，我这里获得的挂载点为：88888888-ney35.cn-shenzhen.nas.aliyuncs.com【本文地址】
