Question - Kubernetes 1.8.1 and deployment/RBAC

[alexellis]

Question - when/how do we get minikube support for Kubernetes 1.8.1 and deployments/RBAC?

What happened:

The transition from Kubernetes 1.7 to 1.8.x seems to be causing issues for our project openfaas/faas-netes. Since the upgrade to 1.8.0 I can no longer use deployments in the namespace apps/v1beta1 auth is also broken in the namespace rbac.authorization.k8s.io/v1beta1.

With Kubernetes 1.8.1 the fix is to move everything to:

apps/v1beta2
rbac.authorization.k8s.io/v1

In Kubernetes 1.8.0 with Minikube the same configuration gives strange errors like this:

Error from server (BadRequest): error when creating "faas.yml": the API version in the data (apps/v1beta2) does not match the expected API version (apps/v1beta1)

It's unfortunate that updating a cluster means maintaining two or three sets of configuration files for each Kubernetes version - 1.7, 1.8.0 and 1.8.1. I'm not sure how we fix this but in the meantime it would be good to have Kubernetes 1.8.1 available for minikube.

I'm not sure how to support this configuration.

$ minikube get-k8s-versions
The following Kubernetes versions are available:

You can get 1.8.1 and RBAC with minikube config set bootstrapper kubeadm, which will eventually be the default option.

With kubeadm, the get-k8s-versions is ignored. For a lengthier explanation, see #2156 (comment)

I'm going to close this, since I don't think we plan on supporting RBAC by default in localkube. You can use the kubeadm bootstrapper, which will be the default in 1.9.
