1.使用Deployment绑定存储： 其中persistentVolumeClaim需要填写已经创建好的PVC。

---
apiVersion: v1
kind: PersistentVolumeClaim
metadata:
  name: pvc-eck-dynamic
spec:
  accessModes:
    - ReadWriteOnce
  resources:
    requests:
      storage: 20Gi
  storageClassName: eck-csi
  volumeMode: Filesystem
---
apiVersion: apps/v1
kind: Deployment
metadata:
  name: deployment-eck-ttt
spec:
  replicas: 1
  selector:
    matchLabels:
      name: deployment-eck
  template:
    metadata:
      name: deployment-eck
      labels:
        name: deployment-eck
    spec:
      nodeSelector:
        "kubernetes.io/os": linux
      containers:
        - name: deployment-eck
          image: ehub.ctcdn.cn/eck/nginx
          command:
            - "/bin/bash"
            - "-c"
            - set -euo pipefail; while true; do echo $(hostname) $(date) >> /mnt/eck/outfile; sleep 1; done
          volumeMounts:
            - name: eck
              mountPath: "/mnt/eck"
      volumes:
        - name: eck
          persistentVolumeClaim:
            claimName: pvc-eck-dynamic

2.使用StatefulSet绑定存储：

有状态的存储也是有状态的，最好使用volumeClaimTemplates，去创建PVC。没有容器实例会绑定一个特定PVC。

---
apiVersion: apps/v1
kind: StatefulSet
metadata:
  name: statefulset-eck
  labels:
    app: nginx
spec:
  serviceName: statefulset-eck
  replicas: 1
  template:
    metadata:
      labels:
        app: nginx
    spec:
      nodeSelector:
        "kubernetes.io/os": linux
      containers:
        - name: statefulset-eck
          image: ehub.ctcdn.cn/eck/nginx
          command:
            - "/bin/bash"
            - "-c"
            - set -euo pipefail; while true; do echo $(date) >> /mnt/eck/outfile; sleep 1; done
          volumeMounts:
            - name: persistent-storage
              mountPath: /mnt/eck
  updateStrategy:
    type: RollingUpdate
  selector:
    matchLabels:
      app: nginx
  volumeClaimTemplates:
    - metadata:
        name: persistent-storage
        annotations:
          volume.beta.kubernetes.io/storage-class: eck-csi
      spec:
        accessModes: ["ReadWriteOnce"]
        resources:
          requests:
            storage: 20Gi
