A persistent volume claim (PVC) is a request for the platform to create a PV for you, and you attach PVs to your pods via a PVC.

In the Kubernetes system, local disks can be used through HostPath , LocalVolume . HostPath : The volume itself does not contain scheduling information. If you want to fix each pod on a node, you need to configure scheduling information, such as nodeSelector, for the pod. LocalVolume : The volume itself contains scheduling information, and the pods using this volume will be fixed on a specific node, which can ensure data continuity. Local Persistent Volumes allow you to access lo...
