What Is a Limit Range?
A limit range is a namespace policy that bounds the resources a single pod or container may request or use, and can supply defaults when none are set. It enforces per-object minimums and maximums, unlike a resource quota which caps the namespace total. Pods that violate the range are rejected at admission.
Why it matters
Limit ranges stop a single oversized or unbounded container from grabbing a whole node. Default values they inject also ensure pods are schedulable and quota-accounted.
