Kubernetes doesn't "failover" like that. Each cluster does it's best to keep your workloads running but stretching across multi-clusters is your responsibility. There is K8S Federation [1](previously called multicluster) which is about deploying from a single host cluster to multiple other ones, but it's still unfinished, and either way K8S doesn't know much about your application itself to be able to perform any kind of failover switch. Usually if it's a stateless app then the solution is using a global load balancer or other networking at the edge to steer traffic to the responsive regions. Databases also tend to have their own replication and distribution strategies handled internally that should be used, along with the above mentioned networking. 1. https://github.com/kubernetes-sigs/kubefed

There's active work on a standard called kubefed [0] that is being worked on. > I want a scale-to-zero node-pool in every region, and one kube master api for the world. Personally, I'd generalize this to: "I want to describe the reliability requirements and configuration for my software and have an automated system solve for where, how many, when, and how to route to it" I want to have something where I can say "I need to have high availability, lowest latency, and X GB of RAM and Y cores" and have a system automatically schedule me wherever compute is cheapest while also intelligently routing traffic to my servers based on client origins.

Multi-cluster kubernetes federation could be the answer (where a "cluster" could be as tiny as a k3s instance running on your Raspberry Pi). However could mean you need one vendor to provide the control-plane software for your vendor-agnostic solution. Nobody has nailed it yet though, AFAIK, but both Rancher and Gloo Federation look promising.
