🔧 Environment Configuration

Required Environment Variables

# JWT Configuration
export JWT_KEY="<256-bit cryptographically secure random>"
export JWT_ISSUER="KArtSell.Aegis"
export JWT_AUDIENCE="KArtSell.Aegis"
export JWT_EXPIRATION_MINUTES="60"

# Database
export KARTSELL_POSTGRES="Host=<prod-db>;Port=5432;Database=kartselldb;Username=kartsell;Password=<secure-password>"

# Optional
export ASPNETCORE_ENVIRONMENT="Production"
export ASPNETCORE_URLS="http://0.0.0.0:5002"

Generate JWT_KEY (256-bit Secure Random)

Option 1: PowerShell

$bytes = New-Object Byte[] 32
[System.Security.Cryptography.RandomNumberGenerator]::Create().GetBytes($bytes)
$key = [Convert]::ToBase64String($bytes)
Write-Host "JWT_KEY=$key"
# Copy output to environment variable

Option 2: OpenSSL

openssl rand -base64 32
# Copy output to environment variable

Option 3: .NET CLI

dotnet user-secrets generate
# Use generated value

📋 Deployment Steps

Step 1: Pre-Deployment Validation ✅

# Verify backend build
cd D:\JobRoomz\KArtSell.Aegis
dotnet build KArtSell.sln -c Release --no-restore
# Expected: Build successful (0 errors)

# Verify frontend build
cd frontend
pnpm install --frozen-lockfile
pnpm build
# Expected: Build complete (dist/ created)

Step 2: Environment Setup 🔐

# Set environment variables (example)
export JWT_KEY="H4sIABST2GYC/0N+JxAkLxI9XxD8kWI5E9fC3x5mJ7dP8="
export KARTSELL_POSTGRES="Host=prod-db.internal;Port=5432;Database=kartselldb;Username=kartsell;Password=prod_secure_password"
export ASPNETCORE_ENVIRONMENT="Production"

# Verify environment
env | grep -E "JWT_|KARTSELL_|ASPNETCORE"

Step 3: Database Migration 🗄️

# Run migrations (BEFORE starting application)
dotnet KArtSell.DbMigrator.dll

# Verify migrations applied
psql -h prod-db -U kartsell -d kartselldb -c "\d public.identity_credential"
# Should show table exists

Step 4: Application Startup 🚀

# Option A: Direct execution
dotnet KArtSell.Host.dll

# Option B: Docker
docker run -d \
  -e JWT_KEY=$JWT_KEY \
  -e KARTSELL_POSTGRES=$KARTSELL_POSTGRES \
  -e ASPNETCORE_ENVIRONMENT=Production \
  -p 5002:5002 \
  kartsell:latest

# Option C: Kubernetes
kubectl apply -f kartsell-deployment.yaml

Step 5: Health Checks ✅

# Wait 10 seconds for startup
sleep 10

# Health check - liveness
curl http://localhost:5002/health/live
# Expected: 200 OK, status=ok

# Health check - readiness
curl http://localhost:5002/health/ready
# Expected: 200 OK, status=ready, database=reachable

Step 6: JWT Authentication Test 🔐

# 1. Login request
curl -X POST http://localhost:5002/api/auth/login \
  -H "Content-Type: application/json" \
  -d '{
    "username": "testuser",
    "password": "testpass",
    "role": "Admin"
  }'

# Expected response:
# {
#   "accessToken": "eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9...",
#   "expiresIn": 3600,
#   "tokenType": "Bearer"
# }

# 2. Extract token
TOKEN="eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9..."

# 3. Test protected endpoint
curl http://localhost:5002/api/identities \
  -H "Authorization: Bearer $TOKEN"
# Expected: 200 OK (or relevant response)

Step 7: Frontend Deployment 🌐

# Option A: Nginx serving static files
cp -r frontend/dist/* /var/www/kartsell/
systemctl restart nginx

# Option B: Embedded in Host wwwroot
dotnet build -c Release # Frontend auto-builds into wwwroot/

# Option C: CDN (if configured)
aws s3 sync frontend/dist/ s3://kartsell-cdn/

🔍 Monitoring & Alerts

Metrics to Track

Authentication Metrics:
├── Successful logins per minute
├── Failed login attempts per minute
├── Token generation latency
├── Token validation latency
├── Invalid token rejections
└── MFA setup/verification (future)

Performance Metrics:
├── API latency (p50, p95, p99)
├── Database connection pool utilization
├── JWT validation overhead
└── Memory usage

Security Metrics:
├── Authentication failures
├── Authorization denials
├── Suspicious IP addresses
└── Brute force attempts

Alert Rules

Condition	Threshold	Action
Failed logins	>10/min	Page on-call
API latency p95	>500ms	Investigate
Database connections	>80%	Scale up
Memory usage	>85%	Restart service
Token validation errors	>5/min	Investigate JWT config
Health check failures	3x consecutive	Automatic rollback

---

🔄 Rollback Procedure

If issues arise within first 24 hours:

# 1. Immediate action - revert to previous version
docker pull kartsell:previous
docker stop kartsell-prod
docker run -d \
  -e JWT_KEY=$JWT_KEY \
  -e KARTSELL_POSTGRES=$KARTSELL_POSTGRES \
  --name kartsell-prod \
  kartsell:previous

# 2. Verify previous version
curl http://localhost:5002/health/live

# 3. Investigate issues
# - Check logs
# - Review error messages
# - Analyze metrics

# 4. Fix issues (if applicable)
# - Correct environment variables
# - Update database if needed
# - Re-deploy with fixes

# 5. Document incident
# - What went wrong
# - Root cause
# - Prevention measures

---
