I set up a Kubernetes cluster in Rancher 2.0 alpha21, and everything seemed to be working as expected. I was running the Rancher container on my laptop, and the rancher agent was installed on a fresh installation of Ubuntu on a machine in our server room. When I stopped the Rancher image on my laptop, kubectl can no longer connect to my cluster. It complains about a certificate error.
Is this the expected behavior? Why does a Rancher container need to be running for kubectl to work?
