Docker Swarm, Kubernetes and failover across multiple data centers and continents: guides for clusters that survive the loss of an entire location, with commands that run on KernelHost servers worldwide.
One data center is a single point of failure. This article builds a Docker Swarm across three continents that can survive the loss of an entire location: manager quorum, WireGuard, one entry point per region, Geo-DNS failover, database replication and operations.
Kubernetes across the US, Europe and Asia, built to tolerate the failure of an entire continent: why etcd cannot handle long distances, one k3s cluster per region, GitOps with Flux, GeoDNS failover, data across regions and how kubeadm differs.
