Alibaba Cloud NAS Configuration

Please follow the steps to configure Alibaba Cloud NAS:

Create ServiceAccount

1. Visit Kubernetes UI. The address is http://IP:31234, replace IP by the actual IP of Kubernetes master node.

2. Selects Kube-system in the Namaspace, and click on CREATE on the right corner of the page.

   

3. Create YAML file(You an create from text input, or create from file). The content of YAML file is in below:

   apiVersion: v1
   kind: ServiceAccount
   metadata:
    labels:
      type: storage-class
      kind: imanager-base
    name: nas-client-controller
   ---
   kind: ClusterRoleBinding
   apiVersion: rbac.authorization.k8s.io/v1
   metadata:
    labels:
      type: storage-class
      kind: imanager-base
     name: run-nfs-client-provisioner
   subjects:
    - kind: ServiceAccount
      name: nas-client-controller
      namespace: kube-system
   roleRef:
    kind: ClusterRole
    name: nfs-client-provisioner-runner
    apiGroup: rbac.authorization.k8s.io

4. Click on UPLOAD.

Install Nas Controller

1. Repeat the steps 1-2 of Create ServiceAccount.

2. Create YAML file. The content of YAML file is in below:

   kind: Deployment
   apiVersion: extensions/v1beta1
   metadata:
    name: alicloud-nas-controller
    namespace: kube-system
   spec:
    strategy:
      type: Recreate
    template:
      metadata:
        labels:
          app: alicloud-nas-controller
      spec:
        tolerations:
        - operator: Exists
        affinity:
          nodeAffinity:
            preferredDuringSchedulingIgnoredDuringExecution:
            - weight: 1
               preference:
                matchExpressions:
                - key: node-role.kubernetes.io/master
                  operator: Exists
        priorityClassName: system-node-critical
        serviceAccount: nas-client-controller
        hostNetwork: true
        containers:
          - name: nfs-provisioner
            image: registry.cn-hangzhou.aliyuncs.com/acs/alicloud-nas-controller:v1.14.3.8-58bf821-aliyun
            env:
            - name: PROVISIONER_NAME
              value: alicloud/nas
            securityContext:
              privileged: true
            volumeMounts:
            - mountPath: /var/log
              name: log
        volumes:
        - hostPath:
            path: /var/log
          name: log

3. Click on UPLOAD.

Create StorageClass

GIS application and database need different StorageClass when binding a same NAS. If you change both GIS application and database to NAS storage, you need to create two StorageClass.

Create Database StorageClass

1. Repeat the steps 1-2 of Create ServiceAccount.

2. Create YAML file. The content of YAML file is in below:

   apiVersion: storage.k8s.io/v1
   kind: StorageClass
   metadata:
    labels:
      kind: imanager-base
    name: alicloud-nas-database
   mountOptions:
   - nolock,tcp,noresvport
   - vers=3
   parameters:
    server: "23a9649583-iaq37.cn-shenzhen.nas.aliyuncs.com:/nasroot1/"
    driver: flexvolume
   provisioner: alicloud/nas
   reclaimPolicy: Delete

3. Click on UPLOAD.

Create GIS Application StorageClass

1. Repeat the steps 1-2 of Create ServiceAccount.

2. Create YAML file. The content of YAML file is in below:

   apiVersion: storage.k8s.io/v1
   kind: StorageClass
   metadata:
    labels:
      kind: imanager-base
    name: alicloud-nas-gisappset
   mountOptions:
   - nolock,tcp,noresvport
   - vers=3
   parameters:
    server: "23a9649583-iaq37.cn-shenzhen.nas.aliyuncs.com:/nasroot1/"
    driver: flexvolume
   provisioner: alicloud/nas
   reclaimPolicy: Delete

3. Click on UPLOAD.

   vi storageClass.conf

2. Adds StorageClass name to the related parameter, as the screenshot below:

   

3. Save and exit.

4. Start up iManager:

   ./startup.sh
