What is Resource Quota?
A Kubernetes policy that limits the total resource consumption in a namespace.
ResourceQuota is a Kubernetes object that limits the aggregate resource usage of a namespace — total CPU, memory, storage, number of pods, services, secrets, etc. When a quota is set and a new resource would exceed it, the request is denied. This prevents one team from starving others in a shared cluster. LimitRange (different object) sets default requests/limits for individual pods. Together they're the primary tools for multi-tenant cluster management.
