Rancher+Kubernetes, how easy to recover from an outage?

Hello,

First time poster here. We are moving into containerization of our applications and our infrastructure team really likes the details Rancher works. I’m curious how persistent is the Kubernetes cluster after, for example, a reboot of the cluster?

I know we can install and configure a cluster running as native services and Rancher runs kubernetes as containers.

Rancher provides us with the level of security and UI management that makes our mostly Windows oriented infrastructure team more comfortable. But I am concerned about outages and how fast is recovery? Does it require human intervention since they are containers, or will it function just like a system service level cluster?
