Resilience Test Pipeline (Bash)

#!/bin/bash
echo "Applying NetworkChaos..."
kubectl apply -f network-delay.yaml

echo "Running health checks..."
for i in {1..5}; do
    curl -s --max-time 1 http://my-app.default.svc.cluster.local/health || echo "Health check failed"
    sleep 5
done

echo "Cleaning up..."
kubectl delete -f network-delay.yaml
