Production Readiness Review — Phase 10-07, Task 5
Date: 2026-03-06
Status: IN PROGRESS
Owner: Architect / PM Autonomy
Target: Production launch sign-off
1. Security Review ✅ AUDITED
1.1 Secrets Management
Current State (Staging):
- ✅ Template pattern (secrets-template.yaml) — safe to commit, never commit real values
- ✅ Multiple deployment options documented:
- Option A: Direct apply (dev/staging only)
- Option B: Sealed Secrets (kubeseal recommended)
- Option C: External Secrets Operator (production best practice)
Production Requirements (Sign-Off Gate):
- MANDATORY: Use sealed-secrets OR External Secrets Operator (Vault/AWS Secrets Manager)
- ❌ Direct secrets YAML not allowed in production
- Recommendation: AWS Secrets Manager + External Secrets Operator (if AWS) OR Vault
- JWT_SECRET generation verified (64-char hex minimum)
- Example:
openssl rand -hex 64 - Rotation policy: Every 90 days
- Example:
- Database credentials use strong passwords (min 32 chars, random)
- TLS private keys protected (encrypted at rest, RBAC restricted)
- No hardcoded secrets in container images (scan before push)
- Secrets rotation procedure documented
Status: ⏳ Awaiting implementation — recommend kubeseal integration pre-production
1.2 RBAC (Role-Based Access Control)
Current State (Staging):
- ✅ Least-privilege design implemented
- ServiceAccount:
gravl-deployer(no cluster-admin) - Role: gravl-staging-deployer (scoped to gravl-staging namespace)
- Permissions: Specific resources (deployments, services, configmaps, ingress)
- ✅ Secrets: READ-ONLY (no create/delete)
- ServiceAccount:
- ✅ ClusterRole for read-only cluster access (namespaces, nodes, storageclasses)
- ✅ No wildcard permissions ("*") — explicit resource lists
- ✅ No escalation paths (verb: "create" on rolebindings denied)
Production Sign-Off:
- Principle of least privilege verified
- No cluster-admin role binding found
- Secrets operations restricted (no create/delete/patch)
- Cross-namespace access explicitly allowed only for monitoring (ingress-nginx)
- Additional: Review production-specific accounts (backup operator, logging sidecar)
- Add LimitRange to prevent resource exhaustion
- Add PodSecurityPolicy / Pod Security Standards enforcement
Status: ✅ APPROVED — RBAC baseline acceptable for production
1.3 Network Policies
Current State (Staging):
- ✅ Default deny ingress (allowlist pattern)
- ✅ Explicit rules for:
- ingress-nginx → backend (port 3000)
- ingress-nginx → frontend (port 80)
- backend → postgres (port 5432)
- gravl-monitoring scraping (port 3001 metrics)
- ✅ Namespace-based pod selection (ingress-nginx selector)
Production Sign-Off:
- Default deny verified
- All inter-pod communication explicitly allowed
- Monitoring namespace access restricted to scrape ports only
- Additional rules needed:
- Egress policies (if restrictive DNS/external access required)
- DNS (CoreDNS access) — currently implicit, should be explicit
- Logs egress (if using external log aggregation)
- Recommendation: Add explicit egress for DNS (port 53 UDP/TCP)
Status: ⏳ CONDITIONAL — Needs DNS egress rule before production
1.4 Encryption & TLS
Current State:
- ✅ TLS secret template provided (staging-tls)
- ✅ Two options documented:
- Self-signed for testing (90 days)
- cert-manager with auto-renewal (recommended)
- ❌ CRITICAL: TLS certificate generation NOT DOCUMENTED FOR PRODUCTION
Production Sign-Off:
- MANDATORY: cert-manager installed on production cluster
- ClusterIssuer configured (Let's Encrypt or internal CA)
- Ingress annotated with cert-manager issuer
- TLS enforced (HTTP → HTTPS redirect)
- Ingress TLS termination verified
Status: ❌ NOT READY — Requires cert-manager setup pre-launch
2. Production Deployment Checklist
| Item | Status | Notes |
|---|---|---|
| Staging deployment complete | ✅ YES | Prometheus, Grafana, AlertManager operational |
| All services healthy (0 restarts) | ✅ YES | Monitored via Prometheus |
| Database migrations validated | ⏳ PENDING | Verify on production cluster |
| DNS/ingress configured for prod | ⏳ PENDING | Staging: staging.gravl.app — Prod: ??? |
| TLS certificate strategy | ❌ NOT SETUP | Action item: Install cert-manager |
| Backup procedure tested | ❌ BLOCKED | StorageClass missing (Task 4 blocker) |
| Secrets sealed | ⏳ PENDING | Awaiting sealed-secrets OR External Secrets |
| Network policies in place | ⏳ PENDING | Add DNS egress rule |
| RBAC reviewed | ✅ APPROVED | Least privilege verified |
| Monitoring dashboards ready | ✅ YES | Grafana dashboards operational |
| Alerting configured | ⏳ PENDING | Review production-specific thresholds |
3. Critical Path to Production (Ordered by Dependency)
Immediate (Block Launch):
- Install cert-manager + create ClusterIssuer (security gate)
- Implement sealed-secrets OR External Secrets Operator (security gate)
- Add DNS egress NetworkPolicy (operational necessity)
- Load test on staging (p95 <200ms verification)
High Priority (Should block): 5. Set up image scanning (ECR/Snyk) 6. Configure production alerting thresholds 7. Create production runbooks
Medium Priority (Launch + 24h): 8. Remediate Loki storage + backup job (Task 4 blockers) 9. Implement secrets rotation automation
4. Security Sign-Off Summary
Approved ✅
- RBAC: Least privilege, no cluster-admin
- Network Policies: Default deny with explicit allowlist
- Secrets template pattern: Safe for committed code
Conditional ⏳
- Secrets management: Requires sealed-secrets OR External Secrets Operator
- TLS/Encryption: Requires cert-manager setup
Not Ready ❌
- Image scanning: Requires ECR/Snyk integration
- Backup integration: Blocked on StorageClass
5. Recommendation
🚫 DO NOT LAUNCH until critical path items #1-4 are complete.
Estimated Time to Production Ready: 6-8 hours
Next Steps:
- Assign critical path tasks to DevOps engineer
- Parallel track: Complete load testing
- Parallel track: Finalize go-live & rollback procedures
- Reconvene for final security sign-off before launch

Addendum: Load Test Configuration & Execution
Load Test Script Location
k8s/production/load-test.js(k6 script)
Load Test Execution (Pre-Production)
# Install k6 (if not already installed)
# macOS: brew install k6
# Linux: apt-get install k6
# Or use Docker: docker run --rm -v $(pwd):/scripts grafana/k6:latest run /scripts/load-test.js
# Run load test against staging environment
export GRAVL_API_URL="https://staging.gravl.app"
k6 run k8s/production/load-test.js
# Expected output (PASSING):
# p95 latency: <200ms
# p99 latency: <500ms
# Error rate: <0.1%
Load Test Results (Staging Baseline)
TO BE COMPLETED: Run load test on staging environment before production launch.
Expected throughput: >100 req/s Expected p95 latency: <200ms Expected error rate: <0.1%
