POLICY-003 Critical workload has no PDB

Summary

A critical workload (e.g. production Deployment) has no PodDisruptionBudget (PDB). During voluntary disruptions (node drain, cluster upgrade) pods may be evicted without a minimum availability guarantee.

Severity

Warning

Example

N/A

Symptoms

  • Report shows: Critical workload has no PDB
  • No PDB targets the workload's pods

Resolution

  1. Create a PodDisruptionBudget that selects the workload's pods (e.g. by label)
  2. Set minAvailable or maxUnavailable based on desired availability (e.g. minAvailable: 1 for single-replica critical app)
  3. Ensure replica count is high enough to satisfy the PDB during drains
