dev.infra-k8s-node-count Calculator
Calculates the minimum number of Kubernetes nodes needed to schedule a given set of pods with headroom for rolling updates in a cloud infrastructure and DevOps context. N+1 node redundancy is the minimum for zero-downtime rolling updates — N+2 or higher is needed if pods cannot be disrupted during node maintenance.
