Kubernetes PodDisruptionBudget Skill

Manage and analyze PodDisruptionBudgets for workload availability during disruptions.

MANDATORY: Discovery-First Pattern

#!/bin/bash

echo "=== PodDisruptionBudgets (all namespaces) ==="
kubectl get pdb --all-namespaces -o custom-columns='NAMESPACE:.metadata.namespace,NAME:.metadata.name,MIN-AVAILABLE:.spec.minAvailable,MAX-UNAVAILABLE:.spec.maxUnavailable,ALLOWED-DISRUPTIONS:.status.disruptionsAllowed,CURRENT:.status.currentHealthy,DESIRED:.status.desiredHealthy,EXPECTED:.status.expectedPods' 2>/dev/null
