# Limit Ranges
> 参考文档:[Limit Ranges](https://kubernetes.io/docs/concepts/policy/limit-range/)
<AdSenseTitle>
默认情况下,容器在 Kubernetes 集群上运行时,不受 [计算资源](/learning/k8s-intermediate/config/computing-resource.html) 的限制。使用 [Resource quota](./rq.html),集群管理员可以针对名称空间限定资源的使用情况。在名称空间内部,一个 Pod或容器的资源消耗不受限制。此时的顾虑在于可能有一个 Pod或容器独占了名称空间的大部分资源。Limit Range 是一种用来限定名称空间内 Pod或容器可以消耗资源数量的策略。
