AUTO-001 HPA replica range too narrow

Summary

An HPA has a min/max replica range that is too narrow (e.g. min equals max or very small range). This limits the benefit of horizontal scaling and can lead to overload or underutilization.

Severity

Warning

Example

N/A

Symptoms

• Report shows: HPA replica range too narrow
• spec.minReplicas and spec.maxReplicas are equal or very close

Resolution

1. Set maxReplicas high enough to handle peak load; set minReplicas for baseline
2. Use metrics and load tests to choose a reasonable range
3. Ensure the target workload (Deployment/StatefulSet) can scale and has sufficient quota
