Direct CSI

Direct CSI is a driver to allocate volumes for pods that require direct access to storage media (eg. MinIO). It maintains a global view of storage in the cluster, and directs pods to run on nodes where volume is provisioned. Each volume is a subdirectory carved out of available drives on the node and mounted into pods.

Visit our documentation for more information.

Install Direct-CSI cli

kubectl krew install directcsi

Install Direct-CSI driver
