TASK 6: KUBERNETES KUSTOMIZE BASE MANIFESTS — COMPLETE ✓
==========================================================

DELIVERABLES:
✓ Created /infra/k8s/base/ directory structure
✓ All 11 manifest files created:
  - kustomization.yaml (root orchestrator)
  - backend-deployment.yaml (1 replica, port 8080, health probes)
  - backend-service.yaml (ClusterIP, port 80→8080)
  - frontend-deployment.yaml (1 replica, port 3000, health probe)
  - frontend-service.yaml (ClusterIP, port 80→3000)
  - postgres-statefulset.yaml (1 replica, 10Gi PVC, pg_isready)
  - postgres-service.yaml (headless + primary service)
  - keycloak-deployment.yaml (1 replica, port 8080, production mode)
  - keycloak-service.yaml (ClusterIP)
  - configmap.yaml (app config + postgres init script)
  - ingress.yaml (path-based routing: / → frontend, /api → backend)

VERIFICATION RESULTS:
✓ kustomize build infra/k8s/base: SUCCESS (456 lines valid YAML)
✓ Resource kinds: ConfigMap, Deployment (3), Ingress, Service (5), StatefulSet
✓ Resource naming: All use consistent workclub- prefix
✓ Health probes: .NET (startup/live/ready), Frontend (/api/health), Postgres (pg_isready)
✓ Environment variables: All services reference ConfigMap/Secrets correctly
✓ Volumes: StatefulSet volumeClaimTemplate 10Gi, ConfigMap mounts for init scripts
✓ Headless service: workclub-postgres-headless with publishNotReadyAddresses: true

REQUIREMENT COVERAGE:
✓ Backend: 1 replica, port 8080, all three .NET health probes
✓ Frontend: 1 replica, port 3000, /api/health probe
✓ PostgreSQL: StatefulSet, 1 replica, port 5432, 10Gi storage, pg_isready check
✓ Keycloak: 1 replica, port 8080, KC_DB=postgres, production start command
✓ ConfigMap: log-level, cors-origins, api-base-url, keycloak-url, database config
✓ Ingress: Single domain routing with pathType: Prefix for /api
✓ Resource limits: Placeholders (100m/256Mi requests, 500m/512Mi limits)
✓ Image tags: :latest placeholder for all app images

LEARNING OUTCOMES:
✓ Documented in .sisyphus/notepads/club-work-manager/learnings.md
✓ Kustomize base+overlay pattern vs Helm
✓ K8s resource naming and labeling conventions
✓ .NET health probe semantics and timing
✓ StatefulSet + headless service pattern for Postgres
✓ PostgreSQL initialization via ConfigMap
✓ Keycloak 26.x production mode configuration
✓ Ingress path-based routing design
✓ ConfigMap strategy for non-sensitive data
✓ Resource request/limit placeholders

GIT COMMIT:
✓ Commit: a103248
✓ Message: "docs(k8s): add Task 6 Kustomize base manifests learnings"
✓ Files modified: .sisyphus/notepads/club-work-manager/learnings.md (415 insertions)

EVIDENCE FILES:
✓ .sisyphus/evidence/task-6-kustomize-base.txt (verification results)
✓ .sisyphus/evidence/task-6-resource-names.txt (resource inventory)
✓ .sisyphus/evidence/task-6-final-summary.txt (this file)

NOTES FOR NEXT TASKS:
- Base manifests ready for Task 25 (dev overlay creation)
- Image tags will be overridden per environment in overlays
- Resource limits will be environment-specific in overlays
- TLS/cert-manager deferred to production overlay
- Health check endpoints require implementation in backend/frontend code
- Secret values (passwords) must be created separately before deployment

STATUS: READY FOR DEPLOYMENT PLANNING
