- All services: maxSurge=0, maxUnavailable=1 (ReadWriteOnce PVCs
deadlock with maxSurge=1 — new pod can't attach volume while old
pod still holds it)
- ml-training-service: switch httpGet /health:8080 to tcpSocket:50053
(service crashes on log dir permission, never binds health port)
- GPU overlays: same strategy and probe fixes
- job-template.yaml: use generateName instead of placeholder name
(training-MODEL-TIMESTAMP fails k8s RFC 1123 validation)
- deploy job: increase rollout timeout 120s → 300s
