Do you test if on K8s < v1.16
Are these changes compatible?

@sleshchenko Deployment resource has been promoted to stable and moved to apps/v1 in 1.9 (december 2017).

But Che already requires k8s v1.8 or earlier because both registries deployment.yaml use apps/v1.

cc @rkratky @themr0c: I haven't see it in the doc but the minimum required version of Kubernetes should be 1.9.

@Kenzim that's available in the nightly build not in the latest stable version of Che yet. Can you be more precise about how you are trying to deploy Che?

[Kenzim]

I just followed kubernetes tutorial, installed on a ubuntu vps, installed helm tiller all that, and then am using chectl to start multi user instance. thanks for reply.

You can try to use chectl next channel instead of stable one:

chectl update next
