It's awesome that they're completely based on Kubernetes now -- super ready to switch over and start using it.
I'd love to hear what you think
I just watched the demo, but I wasn't quite sure how Rancher would deal with specifying Kubernetes Ingresses and Kubernetes Deployments/Pods -- I assume they map the DNS tab and "stacks". Also, I see that you can upload a docker compose file, but I have quite a few kubernetes resource configurations that I'm using for everything right now, I assume you can just as easily upload a resource config? (from somewhere like the stack creation page/menu?)
I have an already running kubernetes cluster and I'm going to give Rancher a go tomorrow, if it's as easy as the demo has made it seem I'm going to be very pleased.
