Kubernetes 1.17.5 incompatible CRD API version

[Antiarchitect]

Stuck installing snapshotter CRDs:
Applying https://github.com/kubernetes-csi/external-snapshotter/tree/master/config/crd (seems like last modification was at Feb 27) without modification:

Manifest under https://github.com/kubernetes-csi/external-snapshotter/tree/master/config/crd are generated automatically by controller-gen. We are not supposed to manually modify those manifests.

Do you already have those volume snapshot CRDs installed on your system? You'll have to uninstall the old ones before installing new ones.

I've uninstalled alpha CRDs

It seems that your helm chart requires apiextensions.k8s.io/v1 but we have v1beta1 in the manifests files. Will need to do some investigation to figure out how to get the manifests generated using v1. It automatically uses v1beta1, even with controller-gen 0.3.0 which is the latest release.

@xing-yang we can use $CONTROLLER_GEN crd:crdVersions=v1,... to generate the apiextensions.k8s.io/v1 CRDs.
