Complete - All Phases Implemented ✅

All 3 phases of infrastructure and CI/CD automation are complete and ready for deployment.

Phase Summary

Phase 1: Core Infrastructure ✅

ECR repositories for Docker images
Application Load Balancer with health checks
Secrets Manager for credentials
ECS Fargate cluster with 8 services

Phase 2: Supporting Infrastructure ✅

VPC with multi-AZ networking
RDS PostgreSQL (central database)
ElastiCache Redis cluster
S3 buckets for storage
IAM roles and policies

Phase 3: CI/CD Automation ✅

GitHub Actions workflows
Automated testing pipeline
Staging deployment automation
Production deployment with approval gates
Automated rollback on failure

GitHub Actions Workflows

1. Test Pipeline (`.github/workflows/test.yml`)

Triggers:

Pull requests to main or develop
Pushes to develop branch

What it does:

✅ Runs unit tests with PostgreSQL + Redis
✅ Runs integration tests
✅ Lints code
✅ Builds all 8 services
✅ Tests Docker builds for each service
✅ Validates Terraform configuration
✅ Runs security scans (Trivy + npm audit)
✅ Uploads coverage reports

Duration: ~10-15 minutes

Blocks merge if: Any test fails

2. Staging Deployment (`.github/workflows/deploy-staging.yml`)

Triggers:

Push to develop branch
Manual trigger via workflow_dispatch

Workflow Steps:

Step 1: Run Tests

Executes full test suite
Can be skipped with workflow_dispatch input

Step 2: Build & Push Images (Parallel)

Builds all 8 Docker images
Pushes to ECR with tags: <commit-sha> and latest
Runs vulnerability scans (Trivy)
Uses BuildKit caching for speed

Step 3: Terraform Apply

Initializes Terraform with S3 backend
Selects/creates staging workspace
Runs terraform plan
Applies changes automatically

Step 4: Database Migrations

Fetches DB URL from Secrets Manager
Runs Prisma migrations on central DB
Runs tenant database migrations

Step 5: Update ECS Services (Parallel)

Forces new deployment for all 8 services
Waits for services to stabilize
Uses Fargate's rolling deployment

Step 6: Health Checks

Gets ALB DNS name
Tests /health endpoint
Runs smoke tests

Step 7: Rollback on Failure

Automatically triggers if health checks fail
Reverts all ECS services
Sends failure notification

Duration: ~20-30 minutes

Cost Impact: Deploys to cost-optimized staging (~$154/month)

3. Production Deployment (`.github/workflows/deploy-production.yml`)

Triggers:

Git tags matching v*.*.* (e.g., v1.0.0)
Manual trigger with version input

Workflow Steps:

Step 1: Validation

Validates version tag format
Shows deployment checkpoint

Step 2: Run Full Test Suite

Unit tests
Integration tests
E2E tests
Security audit
Can be skipped (not recommended)

Step 3: Build & Push Images (Parallel)

Builds with version tags: v1.0.0-abc1234, v1.0.0, latest
STRICT vulnerability scanning - fails on CRITICAL/HIGH
Uploads scan results to GitHub Security

Step 4: Terraform Plan

Generates execution plan
Uploads plan as artifact
No automatic apply

Step 5: Manual Approval Required ⚠️

Uses GitHub Environment protection
Requires manual approval before proceeding
Shows plan summary for review

Step 6: Terraform Apply

Downloads approved plan
Applies infrastructure changes
Updates all resources

Step 7: Database Migrations

Creates backup first
Runs central DB migrations
Runs tenant DB migrations

Step 8: Rolling ECS Update

Updates 2 services at a time (max-parallel: 2)
Maintains 100% availability
Waits for stability between batches

Step 9: Comprehensive Health Checks

Multiple health check attempts (5 retries)
Tests multiple endpoints
Validates all services

Step 10: Rollback on Failure

Automatically reverts to previous task definitions
Service-by-service rollback
Preserves last working state

Duration: ~40-60 minutes (including approval wait)

Safety Features:

Manual approval gate
Version validation
Strict security scanning
Database backups
Rolling updates
Automatic rollback

AWS_ACCESS_KEY_ID
AWS_SECRET_ACCESS_KEY

Staging Secrets: (prefix with STAGING_)

STAGING_DB_USERNAME
STAGING_DB_PASSWORD
STAGING_WORKOS_API_KEY
STAGING_WORKOS_CLIENT_ID
STAGING_OPENAI_API_KEY
STAGING_TAVILY_API_KEY
STAGING_ENCRYPTION_KEY (generate: openssl rand -base64 32)
STAGING_REDIS_PASSWORD

Production Secrets: (prefix with PROD_)

Same list as staging with PROD_ prefix
Use different, production-grade values
Store backups in secure vault (1Password, etc.)

Test Secrets:

TEST_WORKOS_API_KEY (for CI/CD tests)

3. GitHub Environment Protection

For production, configure environment protection:

Go to: Repository → Settings → Environments
Create environment: production
Enable Required reviewers
Add team members who can approve deployments
Optional: Set deployment branch pattern to v*.*.*

Deploying to Staging

Option 1: Automatic (Recommended)

Simply push to develop branch:

git checkout develop
git merge feature-branch
git push origin develop

What happens:

Tests run automatically
Docker images build & push to ECR
Terraform applies infrastructure changes
Database migrations run
ECS services update
Health checks verify deployment
Auto-rollback if anything fails

Monitor deployment:

Go to: Actions tab in GitHub
Watch Deploy to Staging workflow
Check logs for any issues

Option 2: Manual Trigger

Go to: Actions → Deploy to Staging
Click Run workflow
Select branch: develop
Choose whether to skip tests
Click Run workflow

Deploying to Production

Step 1: Create Release Tag

# Ensure you're on main branch
git checkout main
git pull origin main

# Create and push version tag
git tag -a v1.0.0 -m "Release v1.0.0: Initial production deployment"
git push origin v1.0.0

Step 2: Monitor Workflow

Go to: Actions → Deploy to Production
Workflow will start automatically
Wait for manual approval step

Step 3: Review & Approve

Workflow pauses at "Approve Production Deployment"
Review:
- Terraform plan changes
- Test results
- Security scan results
Click Review deployments
Select production environment
Click Approve and deploy

Step 4: Monitor Deployment

Watch the workflow complete:

Database migrations
ECS service updates (2 at a time)
Health checks
Final validation

Step 5: Verify Production

# Get ALB DNS
aws elbv2 describe-load-balancers \
  --names production-helix-alb \
  --query 'LoadBalancers[0].DNSName' \
  --output text

# Test health endpoint
curl https://<ALB-DNS>/health

# Monitor ECS services
aws ecs list-services \
  --cluster production-helix-cluster

# Check CloudWatch logs
aws logs tail /ecs/production/helix/api-gateway --follow

Rollback Procedures

Automatic Rollback

Both workflows include automatic rollback:

Staging: Triggers on health check failure
Production: Triggers on any failure after approval

Manual Rollback (Production)

If you need to manually rollback:

# List previous versions
git tag --sort=-v:refname

# Deploy previous version
git checkout v1.0.0  # Previous working version
git tag -a v1.0.1 -m "Rollback to v1.0.0"
git push origin v1.0.1

Or use workflow_dispatch:

Go to: Actions → Deploy to Production
Click Run workflow
Enter previous version (e.g., v1.0.0)
Approve deployment

Emergency Rollback (ECS Only)

For immediate rollback without full deployment:

# Rollback specific service
aws ecs update-service \
  --cluster production-helix-cluster \
  --service production-helix-api-gateway \
  --task-definition production-helix-api-gateway:5  # Previous revision

# Rollback all services
for service in api-gateway auth-service tenant-service user-service \
               kira-service vera-service data-service notification-service; do
  aws ecs update-service \
    --cluster production-helix-cluster \
    --service production-helix-${service} \
    --force-new-deployment
done

Monitoring & Observability

CloudWatch Dashboards

Access metrics at: AWS Console → CloudWatch → Dashboards

Key Metrics:

ECS CPU/Memory utilization
ALB response times
RDS connections/CPU
Redis memory usage
Error rates (5xx, 4xx)

CloudWatch Alarms

Configured alarms:

RDS: High CPU, low storage, high connections
Redis: High CPU, high memory, evictions
ALB: High 5xx errors, response time, unhealthy hosts

Logs

View logs:

# API Gateway logs
aws logs tail /ecs/production/helix/api-gateway --follow

# All services
aws logs tail /ecs/production/helix/* --follow --format short

# Filter errors
aws logs tail /ecs/production/helix/api-gateway \
  --filter-pattern "ERROR" --follow

Troubleshooting

Common Issues

Issue: Terraform state locked

# Force unlock (use with caution)
terraform force-unlock <LOCK_ID>

Issue: ECS service won't stabilize

# Check task failures
aws ecs describe-services \
  --cluster production-helix-cluster \
  --services production-helix-api-gateway

# Check task logs
aws logs tail /ecs/production/helix/api-gateway --since 30m

Issue: Health checks failing

# Check ALB target health
aws elbv2 describe-target-health \
  --target-group-arn <TARGET_GROUP_ARN>

# Test health endpoint directly
curl http://<TASK_IP>:3000/health

Issue: Database migration failed

# Check migration status
npx prisma migrate status --schema=prisma/central/schema.prisma

# Rollback last migration
npx prisma migrate resolve --rolled-back <MIGRATION_NAME>
