k8s local PV

Kubernetes (k8s) local PV (Persistent Volume) is a type of storage option that allows you to use locally attached storage devices, such as hard disks or solid-state drives (SSDs), as persistent volumes in your Kubernetes cluster. Local PVs are often used for stateful applications that require fast and low-latency access to data.

To use local PVs in your Kubernetes cluster, you first need to provision the local storage devices on each node in your cluster. This can be done using various tools or techniques, such as manually partitioning and formatting the disks or using an automated tool like Kubernetes Local Persistent Volumes (local-path-provisioner).

Once the local storage devices are provisioned, you can create a local PV object in your Kubernetes cluster that describes the properties of the local storage, such as the path and access mode. You can then use this local PV object to create a persistent volume claim (PVC) object that requests a specific amount of storage from the local PV.

Finally, you can mount the PVC object as a volume in your Kubernetes pod, allowing your application to read and write data to the locally attached storage device. This provides a fast and reliable storage option for stateful applications running in your Kubernetes cluster.
