What are Resource Quotas and LimitRange in Kubernetes?

Question

Accepted Answer

**Resource Quotas** — resource limits per namespace. **LimitRange** — limits per Pod/Container.

**Resource Quota:**
```yaml
apiVersion: v1
kind: ResourceQuota
metadata:
  name: team-quota
  namespace: development
spec:
  hard:
    requests.cpu: "4"
    requests.memory: "8Gi"
    limits.cpu: "8"
    limits.memory: "16Gi"
    pods: "20"
    services: "10"
    persistentvolumeclaims: "5"
```

**LimitRange:**
```yaml
apiVersion: v1
kind: LimitRange
metadata:
  name: default-limits
  namespace: development
spec:
  limits:
    - type: Container
      default:
        cpu: "500m"
        memory: "512Mi"
      defaultRequest:
        cpu: "100m"
        memory: "128Mi"
      max:
        cpu: "2"
        memory: "2Gi"
      min:
        cpu: "50m"
        memory: "64Mi"
```

**Verification:** `kubectl get resourcequota -n dev`, `kubectl get limitrange -n dev`.
