RES-003 Namespace has no resource quota

Summary

A namespace has no resource quota when no ResourceQuota exists in that namespace. In multi-tenant or shared clusters, missing quotas can allow one tenant to consume most cluster resources and impact others.

Severity

Warning

Example

N/A

Symptoms

  • Report shows: Namespace <name> has no resource quota
  • No ResourceQuota object exists in the namespace

Resolution

  1. Create a ResourceQuota for the namespace, limiting total requests/limits (e.g. CPU, memory, PVC count)
  2. Set quotas based on capacity and tenant budget; use with LimitRange
  3. For system namespaces (e.g. kube-system), configure quota only if needed
