We currently support 3 versions of Ingress resources. However, extensions/v1beta1 has been removed in v1.22. Users can migrate to other versions.
- networking.k8s.io/v1beta1 API version, available since v1.14. And it was no longer served as of v1.22. - networking.k8s.io/v1 API version, available since v1.19. I hope to delete this version in order to reduce maintenance costs. --- Jintao
