Rancher 1 is superb. After testing Rancher 2 for a couple of weeks I feel sad that they spent time on developing this instead of working on enhancing Rancher 1. I can't seem to find what I can do with Rancher 2 admin panel that I cannot do with what is shipped with Kubernetes. It actually feels more limited and buggy. After those couple of weeks of studying documenations and blog posts I gave up. I was not able to setup any app. Rancher 1 works like a charm. I would have used it for my new projects, but since they are not likely going to develop it I might just go with stock Kubernetes.
