确保已经设置了对应的动态卷的驱动（provisioner 制备器）
基于动态驱动创建对应的存储类
创建PVC （PVC 将会自动根据大小、访问模式等创建PV）
Pod的spec 中通过volumes 和 volumemounts 来完成pvc 的绑定和pvc对应pv的挂载
删除pod 不会删除PVC, 删除PVC也不会导致使用PVC的pod被删除
PVC 在移除时，默认对应的PV也会被移除，但是reclaimPolicy 的值设定为 retain 或者 recycle的情况下，PV会被保留下来

静态卷的制备：

确保对应卷驱动存在
使用驱动创建对应的存储类
手动创建PV
手动创建PVC，PVC 基于大小、访问模式、存储类绑定到符合条件的PV
后续的使用步骤和动态卷一致

hostPath类型的卷，需要保证在对应的节点上目录已经创建完成，具体参考K8S官方文档：

配置 Pod 以使用 PersistentVolume 作为存储 | Kubernetes本文将向你介绍如何配置 Pod 使用 PersistentVolumeClaim 作为存储。以下是该过程的总结：你作为集群管理员创建由物理存储支持的 PersistentVolume。你不会将该卷与任何 Pod 关联。你现在以开发人员或者集群用户的角色创建一个 PersistentVolumeClaim，它将自动绑定到合适的 PersistentVolume。你创建一个使用以上 PersistentVolumeClaim 作为存储的 Pod。准备开始你需要一个包含单个节点的 Kubernetes 集群，并且必须配置 kubectl 命令行工具以便与集群交互。如果还没有单节点集群，可以使用 Minikube 创建一个。熟悉持久卷文档。在你的节点上创建一个 index.html 文件打开集群中的某个节点的 Shell。如何打开 Shell 取决于集群的设置。例如，如果你正在使用 Minikube，那么可以通过输入 minikube ssh 来打开节点的 Shell。在该节点的 Shell 中，创建一个 /mnt/data 目录：# 这里假定你的节点使用 "sudo" 来以超级用户角色执行命令 sudo mkdir /mnt/data 在 /mnt/data 目录中创建一个 index.html 文件：# 这里再次假定你的节点使用 "sudo" 来以超级用户角色执行命令 sudo sh -c "echo 'Hello from Kubernetes storage' > /mnt/data/index.https://kubernetes.io/zh-cn/docs/tasks/configure-pod-container/configure-persistent-volume-storage/#create-a-persistentvolume
