The deployment for Kubernetes 1.15 uses CSI 1.0 and thus is | ||
incompatible with Kubernetes < 1.13. | ||
|
||
The sidecars depend on 1.15 API changes for migration and resizing, | ||
and 1.14 API changes for CSIDriver and CSINode. | ||
|
||
In contrast to the normal deployment, this deployment does not use the | ||
external-attacher sidecar. Instead, it creates a CSIDriver instance | ||
that tells Kubernetes not to use attach (ControllerPublishVolume) at all. |
