Harvester CSI Driver

The Harvester Container Storage Interface (CSI) Driver provides a standard CSI interface used by guest Kubernetes clusters in Harvester. It connects to the host cluster and hot-plugs host volumes to the virtual machines (VMs) to provide native storage performance.

Deploying​

Prerequisites​

  • The Kubernetes cluster is built on top of Harvester virtual machines.
  • The Harvester virtual machines run as guest Kubernetes nodes are in the same namespace.
note

Currently, the Harvester CSI driver only supports single-node read-write(RWO) volumes. Please follow the issue #1992 for future multi-node read-only(ROX) and read-write(RWX) support.

Deploying with Harvester RKE1 Node Driver​

  • Select Harvester(Out-of-tree) option (optional. If you don't need to use the Cloud Provider feature at the same time, you can select the None option).

  • Install Harvester CSI Driver from the Rancher marketplace.

Deploying with Harvester RKE2 Node Driver​

When spinning up a Kubernetes cluster using Rancher RKE2 node driver, the Harvester CSI driver will be deployed when Harvester cloud provider is selected.

Deploying with Harvester K3s Node Driver​
