tar zxvf synology-csi-1.0.0.tar.gz

2 拷贝生成一个client-info.yml文件,并编辑文件对接群晖nas服务器

cd synology-csi-1.0.0
cp config/client-info-template.yml config/client-info.yml

修改client-info.yml

cat client-info.yml 
---
clients:
  - host: 192.168.3.231
    port: 5000
    https: false
    username: wangjinxiong
    password: 21Vianet!@

#host:                      # ipv4 address or domain of the DSM
#port:                      # port for connecting to the DSM
#https:                     # set this true to use https. you need to specify the port to DSM HTTPS port as well
#username:                  # username
#password:                  # password

3 运行脚本安装synology-csi

cd synology-csi-1.0.0
chmod +x scripts/deploy.sh
./scripts/deploy.sh install --all

4 修改SC配置并应用

把默认安装的sc删掉

kubectl delete sc synology-iscsi-storage

vi storage-class.yaml

apiVersion: storage.k8s.io/v1
kind: StorageClass
metadata:
  annotations:
    storageclass.kubernetes.io/is-default-class: "false"
  name: synostorage
provisioner: csi.san.synology.com
parameters:
  fsType: 'ext4'
  dsm: '192.168.3.231'
  location: '/volume1'
reclaimPolicy: Delete
allowVolumeExpansion: true

重新应用:

kubectl apply -f storage-class.yaml

5 创建一个pvc测试

cat pvc0327.yaml 
kind: PersistentVolumeClaim
apiVersion: v1
metadata:
  name: pvc0327
spec:
  accessModes:
    - ReadWriteMany
  resources:
    requests:
      storage: 2Gi
  storageClassName: synostorage
kubectl apply -f pvc0327.yaml

查看pvc情况：

# kubectl get pvc
NAME      STATUS   VOLUME                                     CAPACITY   ACCESS MODES   STORAGECLASS   AGE
pvc0327   Bound    pvc-7c6d335c-2f65-40ae-aa56-962ea93ff86e   2Gi        RWX            synostorage    2s

6 应用statefulsets

cat sts0327.yaml
apiVersion: apps/v1
kind: StatefulSet
metadata:
  name: web
spec:
  serviceName: "nginx-svc"
  replicas: 1
  selector:
    matchLabels:
      app: nginx
  template:
    metadata:
      labels:
        app: nginx
    spec:
      containers:
      - name: nginx
        image: nginx
        ports:
        - containerPort: 80
          name: web
        volumeMounts:
          - name: www
            mountPath: /usr/share/nginx/html
  volumeClaimTemplates:
    - metadata:
        name: www
      spec:
        storageClassName: synostorage
        accessModes:
        -  ReadWriteOnce
        resources:
          requests:
            storage: 1Gi
kubectl apply -f sts0327.yaml

登录容器查看挂载情况：
