 The manifest bundle which captures all the driver components (driver pod which includes the containers csi-provisioner, csi-resizer, csi-snapshotter, gce-pd-driver, csi-driver-registrar;
-csi driver object, rbacs, pod security policies etc) can be picked up from the master branch [overlays](deploy/kubernetes/overlays) directory. We structure the overlays directory, per minor version of kubernetes because not all driver components can be used with all kubernetes versions. For example volume snapshots are supported 1.17+ kubernetes versions thus [stable-1-16](deploy/kubernetes/overlays/stable-1-16) driver manifests does not contain the snapshotter sidecar.

We structure the overlays directory, per minor version of kubernetes because not all driver components can be used with all kubernetes versions. For example, v1 CSIDriver resources are supported in 1.18+ only, so [stable-1-17](deploy/kubernetes/overlays/stable-1-17) driver manifests use the v1beta1 version.
