Is there a way to expose the Kubernetes Dashboard in 2.0?
I don’t think that it is possible in the current version. You must manage your cluster through the Rancher Interface or use kubectl. There is more information in an FAQ (https://rancher.com/docs/rancher/v2.x/en/faq/).
The only information that I manage to find about it in FAQ:
"Rancher will offer the native Kubernetes functionality via kubectl but will also offer our own UI dashboard to allow you to deploy Kubernetes workload without having to understand the full complexity of Kubernetes. However, to fully leverage Kubernetes, we do recommend understanding Kubernetes. We do plan on improving our UX with subsequent releases to make Kubernetes easier to use."
Its not easy. We are working on making it easier/a no-brainer, but in the meantime, I think this guide might work:
