CSI Controller

Goal of this project is to create a simple, single, intelligent CSI controller which can interrogate the Kubernetes version and the CSI driver to determine which controller to load automatically. It will also setup the appropriate objects and settings depending on the Kubernetes version.

Use the container image quay.io/lpabon/csi-controller:v0.2. This version of the CSI controller uses the following versions of the side cars:

• external-provisioner v1.4.0
• external-attacher v2.0.0
• external-resizer master branch
• external-snapshotter release-1.1 branch

RBAC and deployment are available in deploy directory
