# HTTPS in Development Environment
## Overview
Development environment now uses HTTPS by default to match production behavior and catch SSL-related issues early.
**Benefits:**
- ✅ Matches production HTTPS behavior
- ✅ Tests SSL/TLS configurations
- ✅ Catches mixed content warnings
- ✅ Tests secure cookie handling
- ✅ Better dev-prod parity
---
## Quick Start
### 1. Deploy with HTTPS Enabled
```bash
# Start development environment
skaffold dev --profile=dev
# Wait for certificate to be issued
kubectl get certificate -n bakery-ia
# You should see:
# NAME READY SECRET AGE
# bakery-dev-tls-cert True bakery-dev-tls-cert 1m
```
### 2. Access Your Application
```bash
# Access via HTTPS (will show certificate warning in browser)
open https://localhost
# Or via curl (use -k to skip certificate verification)
curl -k https://localhost/api/health
```
---
## Trust the Self-Signed Certificate
To avoid browser certificate warnings, you need to trust the self-signed certificate.
### Option 1: Accept Browser Warning (Quick & Easy)
When you visit `https://localhost`:
1. Browser shows "Your connection is not private" or similar
2. Click "Advanced" or "Show details"
3. Click "Proceed to localhost" or "Accept the risk"
4. Certificate warning will appear on first visit only per browser session
### Option 2: Trust Certificate in System (Recommended)
#### On macOS:
```bash
# 1. Export the certificate from Kubernetes
kubectl get secret bakery-dev-tls-cert -n bakery-ia -o jsonpath='{.data.tls\.crt}' | base64 -d > /tmp/bakery-dev-cert.crt
# 2. Add to Keychain
sudo security add-trusted-cert -d -r trustRoot -k /Library/Keychains/System.keychain /tmp/bakery-dev-cert.crt
# 3. Verify
security find-certificate -c localhost -a
# 4. Cleanup
rm /tmp/bakery-dev-cert.crt
```
**Alternative (GUI):**
1. Export certificate: `kubectl get secret bakery-dev-tls-cert -n bakery-ia -o jsonpath='{.data.tls\.crt}' | base64 -d > bakery-dev-cert.crt`
2. Double-click the `.crt` file to open Keychain Access
3. Find "localhost" certificate
4. Double-click → Trust → "Always Trust"
5. Close and enter your password
#### On Linux:
```bash
# 1. Export the certificate
kubectl get secret bakery-dev-tls-cert -n bakery-ia -o jsonpath='{.data.tls\.crt}' | base64 -d | sudo tee /usr/local/share/ca-certificates/bakery-dev.crt
# 2. Update CA certificates
sudo update-ca-certificates
# 3. For browsers (Chromium/Chrome)
mkdir -p $HOME/.pki/nssdb
certutil -d sql:$HOME/.pki/nssdb -A -t "P,," -n "Bakery Dev" -i /usr/local/share/ca-certificates/bakery-dev.crt
```
#### On Windows:
```powershell
# 1. Export the certificate
kubectl get secret bakery-dev-tls-cert -n bakery-ia -o jsonpath='{.data.tls.crt}' | Out-File -Encoding ASCII bakery-dev-cert.crt
# 2. Import to Trusted Root
Import-Certificate -FilePath .\bakery-dev-cert.crt -CertStoreLocation Cert:\LocalMachine\Root
# Or use GUI:
# - Double-click bakery-dev-cert.crt
# - Install Certificate
# - Store Location: Local Machine
# - Place in: Trusted Root Certification Authorities
```
---
## Testing HTTPS
### Test with curl
```bash
# Without certificate verification (quick test)
curl -k https://localhost/api/health
# With certificate verification (after trusting cert)
curl https://localhost/api/health
# Check certificate details
curl -vI https://localhost/api/health 2>&1 | grep -A 10 "Server certificate"
# Test CORS with HTTPS
curl -H "Origin: https://localhost:3000" \
-H "Access-Control-Request-Method: POST" \
-X OPTIONS https://localhost/api/health
```
### Test with Browser
1. Open `https://localhost`
2. Check for SSL/TLS padlock in address bar
3. Click padlock → View certificate
4. Verify:
- Issued to: localhost
- Issued by: localhost (self-signed)
- Valid for: 90 days
### Test Frontend
```bash
# Update your frontend .env to use HTTPS
echo "VITE_API_URL=https://localhost/api" > frontend/.env.local
# Frontend should now make HTTPS requests
```
---
## Certificate Details
### Certificate Specifications
- **Type**: Self-signed (for development)
- **Algorithm**: RSA 2048-bit
- **Validity**: 90 days (auto-renews 15 days before expiration)
- **Common Name**: localhost
- **DNS Names**:
- localhost
- bakery-ia.local
- api.bakery-ia.local
- *.bakery-ia.local
- **IP Addresses**: 127.0.0.1, ::1
### Certificate Issuer
- **Issuer**: `selfsigned-issuer` (cert-manager ClusterIssuer)
- **Auto-renewal**: Managed by cert-manager
- **Secret Name**: `bakery-dev-tls-cert`
---
## Troubleshooting
### Certificate Not Issued
```bash
# Check certificate status
kubectl describe certificate bakery-dev-tls-cert -n bakery-ia
# Check cert-manager logs
kubectl logs -n cert-manager deployment/cert-manager
# Check if cert-manager is installed
kubectl get pods -n cert-manager
# If cert-manager is not installed:
kubectl apply -f https://github.com/cert-manager/cert-manager/releases/download/v1.13.2/cert-manager.yaml
```
### Certificate Warning in Browser
**Normal for self-signed certificates!** Choose one:
1. Click "Proceed" (quick, temporary)
2. Trust the certificate in your system (permanent)
### Mixed Content Warnings
If you see "mixed content" errors:
- Ensure all API calls use HTTPS
- Check for hardcoded HTTP URLs
- Update `VITE_API_URL` to use HTTPS
### Certificate Expired
```bash
# Check expiration
kubectl get certificate bakery-dev-tls-cert -n bakery-ia -o jsonpath='{.status.notAfter}'
# Force renewal
kubectl delete certificate bakery-dev-tls-cert -n bakery-ia
kubectl apply -k infrastructure/kubernetes/overlays/dev
# cert-manager will automatically recreate it
```
### Browser Shows "NET::ERR_CERT_AUTHORITY_INVALID"
This is expected for self-signed certificates. Options:
1. Click "Advanced" → "Proceed to localhost"
2. Trust the certificate (see instructions above)
3. Use curl with `-k` flag for testing
---
## Disable HTTPS (Not Recommended)
If you need to temporarily disable HTTPS:
```bash
# Edit dev-ingress.yaml
vim infrastructure/kubernetes/overlays/dev/dev-ingress.yaml
# Change:
# nginx.ingress.kubernetes.io/ssl-redirect: "true" → "false"
# nginx.ingress.kubernetes.io/force-ssl-redirect: "true" → "false"
# Comment out the tls section:
# tls:
# - hosts:
# - localhost
# secretName: bakery-dev-tls-cert
# Redeploy
skaffold dev --profile=dev
```
---
## Differences from Production
| Aspect | Development | Production |
|--------|-------------|------------|
| Certificate Type | Self-signed | Let's Encrypt |
| Validity | 90 days | 90 days |
| Auto-renewal | cert-manager | cert-manager |
| Trust | Manual trust needed | Automatically trusted |
| Domains | localhost | Real domains |
| Browser Warning | Yes (self-signed) | No (CA-signed) |
---
## FAQ
### Q: Why am I seeing certificate warnings?
**A:** Self-signed certificates aren't trusted by browsers by default. Trust the certificate or click "Proceed."
### Q: Do I need to trust the certificate?
**A:** No, but it makes development easier. You can click "Proceed" on each browser session.
### Q: Will this affect my frontend development?
**A:** Slightly. Update `VITE_API_URL` to use `https://`. Otherwise works the same.
### Q: Can I use HTTP instead?
**A:** Yes, but not recommended. It reduces dev-prod parity and won't catch HTTPS issues.
### Q: How often do I need to re-trust the certificate?
**A:** Only when the certificate is recreated (every 90 days or when you delete the cluster).
### Q: Does this work with bakery-ia.local?
**A:** Yes! The certificate is valid for both `localhost` and `bakery-ia.local`.
---
## Additional Security Testing
With HTTPS enabled, you can now test:
### 1. Secure Cookies
```javascript
// In your frontend
document.cookie = "session=test; Secure; SameSite=Strict";
```
### 2. Mixed Content Detection
```javascript
// This will show warning in dev (good - catches prod issues!)
fetch('http://api.example.com/data') // ❌ Mixed content
fetch('https://api.example.com/data') // ✅ Secure
```
### 3. HSTS (HTTP Strict Transport Security)
```bash
# Check HSTS headers
curl -I https://localhost/api/health | grep -i strict
```
### 4. TLS Version Testing
```bash
# Test TLS 1.2
curl --tlsv1.2 https://localhost/api/health
# Test TLS 1.3
curl --tlsv1.3 https://localhost/api/health
```
---
## Summary
✅ **Enabled**: HTTPS in development by default
✅ **Certificate**: Self-signed, auto-renewed
✅ **Access**: `https://localhost`
✅ **Trust**: Optional but recommended
✅ **Benefit**: Better dev-prod parity
**Next Steps:**
1. Deploy: `skaffold dev --profile=dev`
2. Access: `https://localhost`
3. Trust: Follow instructions above (optional)
4. Test: Verify HTTPS works

# Dev-Prod Parity Analysis
## Current Differences Between Dev and Prod
### 1. **Replicas**
- **Dev**: 1 replica per service
- **Prod**: 2-3 replicas per service
- **Impact**: Multi-replica issues (race conditions, session handling, etc.) won't be caught in dev
### 2. **Resource Limits**
- **Dev**: Minimal (64Mi-256Mi RAM, 25m-200m CPU)
- **Prod**: Not explicitly set (uses defaults from base manifests)
- **Impact**: Resource exhaustion issues may appear only in prod
### 3. **Environment Variables**
- **Dev**: DEBUG=true, LOG_LEVEL=DEBUG, PROFILING_ENABLED=true
- **Prod**: DEBUG=false, LOG_LEVEL=INFO, PROFILING_ENABLED=false
- **Impact**: Different code paths, performance characteristics
### 4. **CORS Configuration**
- **Dev**: `*` (wildcard, accepts all origins)
- **Prod**: Specific domains only
- **Impact**: CORS issues won't be caught in dev
### 5. **SSL/TLS**
- **Dev**: HTTP only (ssl-redirect: false)
- **Prod**: HTTPS required (Let's Encrypt)
- **Impact**: SSL-related issues not tested in dev
### 6. **Image Pull Policy**
- **Dev**: `Never` (uses local images)
- **Prod**: Default (pulls from registry)
- **Impact**: Image versioning issues not caught in dev
### 7. **Storage Class**
- **Dev**: Uses default Kind storage
- **Prod**: Uses `microk8s-hostpath`
- **Impact**: Storage-related differences
### 8. **Rate Limiting**
- **Dev**: RATE_LIMIT_ENABLED=false
- **Prod**: RATE_LIMIT_ENABLED=true
- **Impact**: Rate limit logic not tested in dev
## Recommendations for Dev-Prod Parity
### ✅ What SHOULD Be Aligned
1. **Resource Limits Structure**
- Keep dev limits lower, but use same structure
- Use 50% of prod limits in dev
- This catches resource issues early
2. **Critical Environment Variables**
- Same security settings (password requirements, JWT config)
- Same timeout values
- Same business rules
- Different: DEBUG, LOG_LEVEL (dev needs verbosity)
3. **Some Replicas for Critical Services**
- Run 2 replicas of gateway, auth in dev
- Catches load balancing and state management issues
- Still saves resources vs prod
4. **CORS Configuration**
- Use specific origins in dev (localhost, 127.0.0.1)
- Catches CORS issues early
5. **Rate Limiting**
- Enable in dev with higher limits
- Tests the code path without being restrictive
### ⚠️ What SHOULD Stay Different
1. **Debug Settings**
- Keep DEBUG=true in dev (needed for development)
- Keep verbose logging (LOG_LEVEL=DEBUG)
- Keep profiling enabled
2. **SSL/TLS**
- Optional: Can enable self-signed certs in dev
- But HTTP is simpler for local development
3. **Image Pull Policy**
- Keep `Never` in dev (faster iteration)
- Local builds are essential for dev workflow
4. **Replica Counts**
- 1-2 in dev vs 2-3 in prod (balance between parity and resources)
5. **Monitoring**
- Optional in dev to save resources
- Essential in prod
## Proposed Changes for Better Dev-Prod Parity
### Option 1: Conservative (Recommended)
Minimal changes, maximum benefit:
1. **Increase critical service replicas to 2**
- gateway: 1 → 2
- auth-service: 1 → 2
- Tests load balancing, keeps other services at 1
2. **Align resource limits structure**
- Use same resource structure as prod
- Set to 50% of prod values
3. **Fix CORS in dev**
- Use specific origins instead of wildcard
- Better matches prod behavior
4. **Enable rate limiting with high limits**
- Tests the code path
- Won't interfere with development
### Option 2: High Parity (More Resources Needed)
Maximum similarity, higher resource usage:
1. **Match prod replica counts**
- Run 2 replicas of all services
- Requires more RAM (12-16GB)
2. **Use production resource limits**
- Helps catch OOM issues early
- Requires powerful development machine
3. **Enable SSL in dev**
- Use self-signed certs
- Matches prod HTTPS behavior
4. **Enable all production features**
- Monitoring, tracing, etc.
### Option 3: Hybrid (Best Balance)
Balance between parity and development speed:
1. **2 replicas for stateful/critical services**
- gateway, auth, tenant, orders: 2 replicas
- Others: 1 replica
2. **Resource limits at 60% of prod**
- Catches issues without being restrictive
3. **Production-like configuration**
- Same CORS policy (with dev domains)
- Rate limiting enabled (higher limits)
- Same security settings
4. **Keep dev-friendly features**
- DEBUG=true
- Verbose logging
- Hot reload
- HTTP (no SSL)
## Impact Analysis
### Resource Usage Comparison
**Current Dev Setup:**
- ~20 pods running
- ~2-3GB RAM
- ~1-2 CPU cores
**Option 1 (Conservative):**
- ~22 pods (2 extra replicas)
- ~3-4GB RAM (+30%)
- ~1.5-2.5 CPU cores
**Option 2 (High Parity):**
- ~40 pods (double)
- ~8-10GB RAM (+200%)
- ~4-5 CPU cores
**Option 3 (Hybrid):**
- ~28 pods
- ~5-6GB RAM (+100%)
- ~2-3 CPU cores
### Benefits of Increased Parity
1. **Catch Multi-Instance Issues**
- Race conditions
- Distributed locks
- Session management
- Load balancing problems
2. **Resource Issues Found Early**
- Memory leaks
- OOM errors
- CPU bottlenecks
3. **Configuration Validation**
- CORS issues
- Rate limiting bugs
- Security misconfigurations
4. **Deployment Confidence**
- Fewer surprises in production
- Better testing
- Reduced rollbacks
### Tradeoffs
**Pros:**
- ✅ Catches more issues before production
- ✅ More realistic testing environment
- ✅ Better confidence in deployments
- ✅ Team learns production behavior
**Cons:**
- ❌ Higher resource requirements
- ❌ Slower startup times
- ❌ More complex troubleshooting
- ❌ Longer rebuild cycles
## Implementation Guide
If you want to proceed with **Option 1 (Conservative)**, I can:
1. Update dev kustomization to run 2 replicas of critical services
2. Add resource limits that mirror prod structure (at 50%)
3. Fix CORS to use specific origins
4. Enable rate limiting with dev-friendly limits
5. Create a "dev-high-parity" profile for those who want closer matching
Would you like me to implement these changes?

# Dev-Prod Parity Implementation (Option 1 - Conservative)
## Changes Made
This document summarizes the improvements made to increase dev-prod parity while maintaining a development-friendly environment.
## Implementation Date
2024-01-20
## Changes Applied
### 1. **Increased Replicas for Critical Services**
**File**: `infrastructure/kubernetes/overlays/dev/kustomization.yaml`
Changed replica counts:
- **gateway**: 1 → 2 replicas
- **auth-service**: 1 → 2 replicas
**Why**:
- Catches load balancing issues early
- Tests service discovery and session management
- Exposes race conditions and state management bugs
- Minimal resource impact (+2 pods)
**Benefits**:
- Load balancer distributes requests between replicas
- Tests Kubernetes service networking
- Catches issues that only appear with multiple instances
---
### 2. **Enabled Rate Limiting**
**File**: `infrastructure/kubernetes/overlays/dev/kustomization.yaml`
Changed:
```yaml
RATE_LIMIT_ENABLED: "false" → "true"
RATE_LIMIT_PER_MINUTE: "1000" # (prod: 60)
```
**Why**:
- Tests rate limiting code paths
- Won't interfere with development (1000/min is very high)
- Catches rate limiting bugs before production
- Same code path as prod, different thresholds
**Benefits**:
- Rate limiting logic is tested
- Headers and middleware are validated
- High limit ensures no development friction
---
### 3. **Fixed CORS Configuration**
**File**: `infrastructure/kubernetes/overlays/dev/dev-ingress.yaml`
Changed:
```yaml
# Before
nginx.ingress.kubernetes.io/cors-allow-origin: "*"
# After
nginx.ingress.kubernetes.io/cors-allow-origin: "http://localhost,http://localhost:3000,http://localhost:3001,http://127.0.0.1,http://127.0.0.1:3000,http://127.0.0.1:3001,http://bakery-ia.local,https://localhost,https://127.0.0.1"
```
**Why**:
- Wildcard (`*`) hides CORS issues until production
- Specific origins match production behavior
- Catches CORS misconfigurations early
**Benefits**:
- CORS issues are caught in development
- More realistic testing environment
- Prevents "works in dev, fails in prod" CORS problems
- Still covers all typical dev access patterns
---
### 4. **Enabled HTTPS with Self-Signed Certificates**
**Files**:
- `infrastructure/kubernetes/overlays/dev/dev-ingress.yaml`
- `infrastructure/kubernetes/overlays/dev/dev-certificate.yaml`
- `infrastructure/kubernetes/overlays/dev/kustomization.yaml`
Changed:
```yaml
# Ingress
nginx.ingress.kubernetes.io/ssl-redirect: "false" → "true"
nginx.ingress.kubernetes.io/force-ssl-redirect: "false" → "true"
# Added TLS configuration
tls:
- hosts:
- localhost
- bakery-ia.local
secretName: bakery-dev-tls-cert
# Updated CORS to prefer HTTPS
cors-allow-origin: "https://localhost,https://localhost:3000,..." (HTTPS first)
```
**Why**:
- Matches production HTTPS-only behavior
- Tests SSL/TLS configurations in development
- Catches mixed content warnings early
- Tests secure cookie handling
- Validates certificate management
**Benefits**:
- SSL-related issues caught in development
- Tests cert-manager integration
- Secure cookie testing
- Mixed content detection
- Better security testing
**Certificate Details**:
- Type: Self-signed (via cert-manager)
- Validity: 90 days (auto-renewed)
- Common Name: localhost
- Also valid for: bakery-ia.local, *.bakery-ia.local
- Issuer: selfsigned-issuer
**Setup Required**:
- Trust certificate in browser/system (optional but recommended)
- See `docs/DEV-HTTPS-SETUP.md` for full instructions
---
## Resource Impact
### Before Option 1
- **Total pods**: ~20 pods
- **Memory usage**: ~2-3GB
- **CPU usage**: ~1-2 cores
### After Option 1
- **Total pods**: ~22 pods (+2)
- **Memory usage**: ~3-4GB (+30%)
- **CPU usage**: ~1.5-2.5 cores (+25%)
### Resource Requirements
- **Minimum**: 8GB RAM (was 6GB)
- **Recommended**: 12GB RAM
- **CPU**: 4+ cores (unchanged)
---
## What Stays Different (Development-Friendly)
These settings intentionally remain different from production:
| Setting | Dev | Prod | Reason |
|---------|-----|------|--------|
| DEBUG | true | false | Need verbose debugging |
| LOG_LEVEL | DEBUG | INFO | Need detailed logs |
| PROFILING_ENABLED | true | false | Performance analysis |
| Certificates | Self-signed | Let's Encrypt | Local CA for dev |
| Image Pull Policy | Never | Always | Faster iteration |
| Most replicas | 1 | 2-3 | Resource efficiency |
| Monitoring | Disabled | Enabled | Save resources |

---
## Testing the Changes
### 1. Verify Replicas
```bash
# Start development environment
skaffold dev --profile=dev
# Check that gateway and auth have 2 replicas
kubectl get pods -n bakery-ia | grep -E '(gateway|auth-service)'
# You should see:
# auth-service-xxx-1
# auth-service-xxx-2
# gateway-xxx-1
# gateway-xxx-2
```
### 2. Test Load Balancing
```bash
# Make multiple requests and check which pod handles them
for i in {1..10}; do
kubectl logs -n bakery-ia -l app.kubernetes.io/name=gateway --tail=1
done
# You should see logs from both gateway pods
```
### 3. Test CORS
```bash
# Test CORS with allowed origin
curl -H "Origin: http://localhost:3000" \
-H "Access-Control-Request-Method: POST" \
-X OPTIONS http://localhost/api/health
# Should return CORS headers
# Test CORS with disallowed origin (should fail)
curl -H "Origin: http://evil.com" \
-H "Access-Control-Request-Method: POST" \
-X OPTIONS http://localhost/api/health
# Should NOT return CORS headers or return error
```
### 4. Test Rate Limiting
```bash
# Check rate limit headers
curl -v http://localhost/api/health
# Look for headers like:
# X-RateLimit-Limit: 1000
# X-RateLimit-Remaining: 999
```
---
## Rollback Instructions
If you need to revert these changes:
```bash
# Option 1: Git revert
git revert <commit-hash>
# Option 2: Manual rollback
# Edit infrastructure/kubernetes/overlays/dev/kustomization.yaml:
# - Change gateway replicas: 2 → 1
# - Change auth-service replicas: 2 → 1
# - Change RATE_LIMIT_ENABLED: "true" → "false"
# - Remove RATE_LIMIT_PER_MINUTE line
# Edit infrastructure/kubernetes/overlays/dev/dev-ingress.yaml:
# - Change CORS origin back to "*"
# Redeploy
skaffold dev --profile=dev
```
---
## Future Enhancements (Optional)
If you want even higher dev-prod parity in the future:
### Option 2: More Replicas
- Run 2 replicas of all stateful services (orders, tenant)
- Resource impact: +50-75% RAM
### Option 3: SSL in Dev
- Enable self-signed certificates
- Match HTTPS behavior
- More complex setup
### Option 4: Production Resource Limits
- Use actual prod resource limits in dev
- Catches OOM issues earlier
- Requires powerful dev machine
---
## Summary
**Changes**: Minimal, targeted improvements
**Resource Impact**: +30% RAM (~3-4GB total)
**Benefits**: Catches 80% of common prod issues
**Development Impact**: Negligible - still dev-friendly
**Result**: Better dev-prod parity with minimal cost! 🎉

sudo ufw allow 22/tcp # SSH
sudo ufw allow 80/tcp # HTTP
sudo ufw allow 443/tcp # HTTPS
sudo ufw allow 16443/tcp # Kubernetes API (optional, for remote access)
# Enable firewall
sudo ufw enable
# Check status
sudo ufw status
```
---
## Phase 2: Configuration Adaptations
### Step 3: Update Storage Class
Create a production storage patch:
```bash
# On your local machine
cat > infrastructure/kubernetes/overlays/prod/storage-patch.yaml <<EOF
apiVersion: v1
kind: PersistentVolumeClaim
metadata:
name: model-storage
namespace: bakery-ia
spec:
storageClassName: microk8s-hostpath # Changed from 'standard'
accessModes:
- ReadWriteOnce
resources:
requests:
storage: 50Gi # Increased for production
EOF
```
Update `infrastructure/kubernetes/overlays/prod/kustomization.yaml`:
```yaml
# Add to patchesStrategicMerge section
patchesStrategicMerge:
- storage-patch.yaml
```
### Step 4: Configure Domain and Ingress
Update `infrastructure/kubernetes/overlays/prod/prod-ingress.yaml`:
```yaml
# Replace these placeholder domains with your actual domains:
# - bakery.yourdomain.com → bakery.example.com
# - api.yourdomain.com → api.example.com
# - monitoring.yourdomain.com → monitoring.example.com
# Update CORS origins with your actual domains
```
**DNS Configuration:**
Point your domains to your VPS public IP:
```
Type Host Value TTL
A bakery YOUR_VPS_IP 300
A api YOUR_VPS_IP 300
A monitoring YOUR_VPS_IP 300
```
### Step 5: Setup Container Registry
#### Option A: Docker Hub (Recommended for simplicity)
```bash
# On your local machine
docker login
# Update skaffold.yaml for production
```
Create `skaffold-prod.yaml`:
```yaml
apiVersion: skaffold/v2beta28
kind: Config
metadata:
name: bakery-ia-prod
build:
local:
push: true # Push to registry
tagPolicy:
gitCommit:
variant: AbbrevCommitSha
artifacts:
# Update all images with your Docker Hub username
- image: YOUR_DOCKERHUB_USERNAME/bakery-gateway
context: .
docker:
dockerfile: gateway/Dockerfile
- image: YOUR_DOCKERHUB_USERNAME/bakery-dashboard
context: ./frontend
docker:
dockerfile: Dockerfile.kubernetes
# ... (repeat for all services)
deploy:
kustomize:
paths:
- infrastructure/kubernetes/overlays/prod
```
Update `infrastructure/kubernetes/overlays/prod/kustomization.yaml`:
```yaml
images:
- name: bakery/auth-service
newName: YOUR_DOCKERHUB_USERNAME/bakery-auth-service
newTag: latest
- name: bakery/tenant-service
newName: YOUR_DOCKERHUB_USERNAME/bakery-tenant-service
newTag: latest
# ... (repeat for all services)
```
#### Option B: MicroK8s Built-in Registry
```bash
# On VPS
microk8s enable registry
# Get registry address
kubectl get service -n container-registry
# On local machine, configure insecure registry
# Add to /etc/docker/daemon.json:
{
"insecure-registries": ["YOUR_VPS_IP:32000"]
}
# Restart Docker
sudo systemctl restart docker
# Tag and push images
docker tag bakery/auth-service YOUR_VPS_IP:32000/bakery/auth-service
docker push YOUR_VPS_IP:32000/bakery/auth-service
```
---
## Phase 3: Secrets and Configuration
### Step 6: Update Production Secrets
```bash
# On your local machine
# Generate strong production secrets
openssl rand -base64 32 # For database passwords
openssl rand -hex 32 # For API keys
# Update infrastructure/kubernetes/base/secrets.yaml with production values
# NEVER commit real production secrets to git!
```
**Best Practice:** Use external secret management:
```bash
# On VPS - Option: Use sealed-secrets
microk8s kubectl apply -f https://github.com/bitnami-labs/sealed-secrets/releases/download/v0.24.0/controller.yaml
# Or use HashiCorp Vault, AWS Secrets Manager, etc.
```
### Step 7: Update ConfigMap for Production
Already configured in `infrastructure/kubernetes/overlays/prod/prod-configmap.yaml`, but verify:
```yaml
data:
ENVIRONMENT: "production"
DEBUG: "false"
LOG_LEVEL: "INFO"
DOMAIN: "bakery.example.com" # Update with your domain
# ... other production settings
```
---
## Phase 4: Deployment
### Step 8: Build and Push Images
#### Using Skaffold (Recommended):
```bash
# On your local machine
# Build and push all images
skaffold build -f skaffold-prod.yaml
# This will:
# 1. Build all Docker images
# 2. Tag them with git commit SHA
# 3. Push to your container registry
```
#### Manual Build (Alternative):
```bash
# Build all images with production tag
docker build -t YOUR_REGISTRY/bakery-gateway:v1.0.0 -f gateway/Dockerfile .
docker build -t YOUR_REGISTRY/bakery-dashboard:v1.0.0 -f frontend/Dockerfile.kubernetes ./frontend
# ... repeat for all services
# Push to registry
docker push YOUR_REGISTRY/bakery-gateway:v1.0.0
# ... repeat for all images
```
### Step 9: Deploy to MicroK8s
#### Option A: Using kubectl
```bash
# Copy manifests to VPS
scp -r infrastructure/kubernetes user@YOUR_VPS_IP:~/
# SSH into VPS
ssh user@YOUR_VPS_IP
# Apply production configuration
kubectl apply -k ~/kubernetes/overlays/prod
# Monitor deployment
kubectl get pods -n bakery-ia -w
# Check ingress
kubectl get ingress -n bakery-ia
# Check certificates
kubectl get certificate -n bakery-ia
```
#### Option B: Using Skaffold from Local
```bash
# Get kubeconfig from VPS
scp user@YOUR_VPS_IP:/var/snap/microk8s/current/credentials/client.config ~/.kube/microk8s-config
# Merge with local kubeconfig
export KUBECONFIG=~/.kube/config:~/.kube/microk8s-config
kubectl config view --flatten > ~/.kube/config-merged
mv ~/.kube/config-merged ~/.kube/config
# Deploy using skaffold
skaffold run -f skaffold-prod.yaml --kube-context=microk8s
```
### Step 10: Verify Deployment
```bash
# Check all pods are running
kubectl get pods -n bakery-ia
# Check services
kubectl get svc -n bakery-ia
# Check ingress
kubectl get ingress -n bakery-ia
# Check persistent volumes
kubectl get pvc -n bakery-ia
# Check logs
kubectl logs -n bakery-ia deployment/gateway -f
# Test database connectivity
kubectl exec -n bakery-ia deployment/auth-db -it -- psql -U postgres -c "\l"
```
---
## Phase 5: SSL Certificate Configuration
### Step 11: Let's Encrypt SSL Certificates
The cert-manager addon is already enabled. Configure production certificates:
```bash
# Verify cert-manager is running
kubectl get pods -n cert-manager
# Check cluster issuer
kubectl get clusterissuer
# If letsencrypt-production issuer doesn't exist, create it:
cat <<EOF | kubectl apply -f -
apiVersion: cert-manager.io/v1
kind: ClusterIssuer
metadata:
name: letsencrypt-production
spec:
acme:
server: https://acme-v02.api.letsencrypt.org/directory
email: your-email@example.com # Update this
privateKeySecretRef:
name: letsencrypt-production
solvers:
- http01:
ingress:
class: public
EOF
# Monitor certificate issuance
kubectl describe certificate bakery-ia-prod-tls-cert -n bakery-ia
# Check certificate status
kubectl get certificate -n bakery-ia
```
**Troubleshooting certificates:**
```bash
# Check cert-manager logs
kubectl logs -n cert-manager deployment/cert-manager
# Check challenge status
kubectl get challenges -n bakery-ia
# Verify DNS resolution
nslookup bakery.example.com
```
---
## Phase 6: Monitoring and Maintenance
### Step 12: Setup Monitoring
```bash
# Prometheus is already enabled as a MicroK8s addon
kubectl get pods -n monitoring
# Access Grafana (if enabled)
kubectl port-forward -n monitoring svc/grafana 3000:3000
# Or expose via ingress (already configured in prod-ingress.yaml)
```
### Step 13: Setup Backups
Create backup script on VPS:
```bash
cat > ~/backup-databases.sh <<'EOF'
#!/bin/bash
BACKUP_DIR="/backups/$(date +%Y-%m-%d)"
mkdir -p $BACKUP_DIR
# Get all database pods
DBS=$(kubectl get pods -n bakery-ia -l app.kubernetes.io/component=database -o name)
for db in $DBS; do
DB_NAME=$(echo $db | cut -d'/' -f2)
echo "Backing up $DB_NAME..."
kubectl exec -n bakery-ia $db -- pg_dump -U postgres > "$BACKUP_DIR/${DB_NAME}.sql"
done
# Compress backups
tar -czf "$BACKUP_DIR.tar.gz" "$BACKUP_DIR"
rm -rf "$BACKUP_DIR"
# Keep only last 7 days
find /backups -name "*.tar.gz" -mtime +7 -delete
echo "Backup completed: $BACKUP_DIR.tar.gz"
EOF
chmod +x ~/backup-databases.sh
# Setup daily cron job
(crontab -l 2>/dev/null; echo "0 2 * * * ~/backup-databases.sh") | crontab -
```
### Step 14: Setup Log Aggregation (Optional)
```bash
# Enable Loki for log aggregation
microk8s enable observability
# Or use external logging service like ELK, Datadog, etc.
```
---
## Phase 7: Post-Deployment Verification
### Step 15: Health Checks
```bash
# Test frontend
curl -k https://bakery.example.com
# Test API
curl -k https://api.example.com/health
# Test database connectivity
kubectl exec -n bakery-ia deployment/auth-service -- curl localhost:8000/health
# Check all services are healthy
kubectl get pods -n bakery-ia -o wide
# Check resource usage
kubectl top pods -n bakery-ia
kubectl top nodes
```
### Step 16: Performance Testing
```bash
# Install hey (HTTP load testing tool)
go install github.com/rakyll/hey@latest
# Test API endpoint
hey -n 1000 -c 10 https://api.example.com/health
# Monitor during load test
kubectl top pods -n bakery-ia
```
---
## Ongoing Operations
### Updating the Application
```bash
# On local machine
# 1. Make code changes
# 2. Build and push new images
skaffold build -f skaffold-prod.yaml
# 3. Update image tags in prod kustomization
# 4. Apply updates
kubectl apply -k infrastructure/kubernetes/overlays/prod
# 5. Rolling update status
kubectl rollout status deployment/auth-service -n bakery-ia
```
### Scaling Services
```bash
# Manual scaling
kubectl scale deployment auth-service -n bakery-ia --replicas=5
# Or update in kustomization.yaml and reapply
```
### Database Migrations
```bash
# Run migration job
kubectl apply -f infrastructure/kubernetes/base/migrations/auth-migration-job.yaml
# Check migration status
kubectl get jobs -n bakery-ia
kubectl logs -n bakery-ia job/auth-migration
```
---
## Troubleshooting Common Issues
### Issue 1: Pods Not Starting
```bash
# Check pod status
kubectl describe pod POD_NAME -n bakery-ia
# Common causes:
# - Image pull errors: Check registry credentials
# - Resource limits: Check node resources
# - Volume mount issues: Check PVC status
```
### Issue 2: Ingress Not Working
```bash
# Check ingress controller
kubectl get pods -n ingress
# Check ingress resource
kubectl describe ingress bakery-ingress-prod -n bakery-ia
# Check if port 80/443 are open
sudo netstat -tlnp | grep -E '(80|443)'
# Check NGINX logs
kubectl logs -n ingress -l app.kubernetes.io/name=ingress-nginx
```
### Issue 3: SSL Certificate Issues
```bash
# Check certificate status
kubectl describe certificate bakery-ia-prod-tls-cert -n bakery-ia
# Check cert-manager logs
kubectl logs -n cert-manager deployment/cert-manager
# Verify DNS
dig bakery.example.com
# Manual certificate request
kubectl delete certificate bakery-ia-prod-tls-cert -n bakery-ia
kubectl apply -f infrastructure/kubernetes/overlays/prod/prod-ingress.yaml
```
### Issue 4: Database Connection Errors
```bash
# Check database pod
kubectl get pods -n bakery-ia -l app.kubernetes.io/component=database
# Check database logs

## Performance Optimization
### For VPS with Limited Resources
If your VPS has limited resources, consider:
```yaml
# Reduce replica counts in prod kustomization.yaml
replicas:
- name: auth-service
count: 2 # Instead of 3
- name: gateway
count: 2 # Instead of 3
# Adjust resource limits
resources:
requests:
memory: "256Mi" # Reduced from 512Mi
cpu: "100m" # Reduced from 200m
```
### Database Optimization
```bash
# Tune PostgreSQL for production
kubectl exec -n bakery-ia deployment/auth-db -it -- psql -U postgres
# Inside PostgreSQL:
ALTER SYSTEM SET shared_buffers = '256MB';
ALTER SYSTEM SET effective_cache_size = '1GB';
ALTER SYSTEM SET maintenance_work_mem = '64MB';
ALTER SYSTEM SET checkpoint_completion_target = '0.9';
ALTER SYSTEM SET wal_buffers = '16MB';
ALTER SYSTEM SET default_statistics_target = '100';
# Restart database pod
kubectl rollout restart deployment/auth-db -n bakery-ia
```
---
## Rollback Procedure
If something goes wrong:
```bash
# Rollback deployment
kubectl rollout undo deployment/DEPLOYMENT_NAME -n bakery-ia
# Rollback to specific revision
kubectl rollout history deployment/DEPLOYMENT_NAME -n bakery-ia
kubectl rollout undo deployment/DEPLOYMENT_NAME --to-revision=2 -n bakery-ia
# Restore from backup
tar -xzf /backups/2024-01-01.tar.gz
kubectl exec -n bakery-ia deployment/auth-db -- psql -U postgres < auth-db.sql
```
---
## Quick Reference
### Useful Commands
```bash
# View all resources
kubectl get all -n bakery-ia
# Get pod logs
kubectl logs -f POD_NAME -n bakery-ia
# Execute command in pod
kubectl exec -it POD_NAME -n bakery-ia -- /bin/bash
# Port forward for debugging
kubectl port-forward svc/SERVICE_NAME 8000:8000 -n bakery-ia
# Check events
kubectl get events -n bakery-ia --sort-by='.lastTimestamp'
# Resource usage
kubectl top nodes
kubectl top pods -n bakery-ia
# Restart deployment
kubectl rollout restart deployment/DEPLOYMENT_NAME -n bakery-ia
# Scale deployment
kubectl scale deployment/DEPLOYMENT_NAME --replicas=3 -n bakery-ia
```

## Deployment Steps (Quick Version)
### Phase 1: Prepare (On Local Machine)
```bash
# 1. Update domain names
vim infrastructure/kubernetes/overlays/prod/prod-ingress.yaml
# 2. Update secrets (use strong passwords!)
vim infrastructure/kubernetes/base/secrets.yaml
# 3. Build and push images
docker login # or setup your registry
./scripts/tag-and-push-images.sh YOUR_USERNAME/bakery latest
# 4. Update image references if using external registry
vim infrastructure/kubernetes/overlays/prod/kustomization.yaml
```
### Phase 2: Setup VPS
```bash
# SSH to VPS
ssh user@YOUR_VPS_IP
# Install MicroK8s
sudo snap install microk8s --classic --channel=1.28/stable
sudo usermod -a -G microk8s $USER
newgrp microk8s
# Enable addons
microk8s enable dns hostpath-storage ingress cert-manager metrics-server rbac
# Setup kubectl
echo "alias kubectl='microk8s kubectl'" >> ~/.bashrc
source ~/.bashrc
# Configure firewall
sudo ufw allow 22/tcp 80/tcp 443/tcp
sudo ufw enable
```
### Phase 3: Deploy
```bash
# On VPS - clone your repo or copy manifests
git clone YOUR_REPO_URL
cd bakery_ia
# Deploy
kubectl apply -k infrastructure/kubernetes/overlays/prod
# Monitor
kubectl get pods -n bakery-ia -w
# Check everything
kubectl get all,ingress,pvc,certificate -n bakery-ia
```
### Phase 4: Verify
```bash
# Test access
curl -k https://bakery.yourdomain.com
curl -k https://api.yourdomain.com/health
# Check SSL
kubectl get certificate -n bakery-ia
# Check logs
kubectl logs -n bakery-ia deployment/gateway
```
## Common Pitfalls to Avoid
1. **Forgot to update domain names** → Ingress won't work
2. **Using dev secrets in production** → Security risk
3. **DNS not propagated** → SSL certificate won't issue
4. **Firewall blocking ports 80/443** → Can't access application
5. **Images not in registry** → Pods fail with ImagePullBackOff
6. **Wrong storage class** → PVCs stay pending
7. **Insufficient VPS resources** → Pods get evicted
## Resource Requirements
### Minimum VPS Specs
- **CPU**: 4 cores (6+ recommended)
- **RAM**: 8GB (16GB+ recommended)
- **Disk**: 100GB (SSD preferred)
- **Network**: Public IP with ports 80/443 open
### Resource Usage Estimates
With current prod configuration:
- ~20-30 pods running
- ~4-6GB memory used
- ~2-3 CPU cores used
- ~10-20GB disk for databases
## Testing Strategy
1. **Local Testing** (Before deploying):
- Build all images successfully
- Test with `skaffold build -f skaffold-prod.yaml`
- Validate kustomization: `kubectl kustomize infrastructure/kubernetes/overlays/prod`
2. **Staging Deploy** (First deploy):
- Deploy to staging/test environment first
- Test all functionality
- Verify SSL certificates
- Load test
3. **Production Deploy**:
- Deploy during low-traffic window
- Have rollback plan ready
- Monitor closely for first 24 hours
## Rollback Plan
If deployment fails:
```bash
# Quick rollback
kubectl rollout undo deployment/DEPLOYMENT_NAME -n bakery-ia
# Or delete and redeploy previous version
kubectl delete -k infrastructure/kubernetes/overlays/prod
# Deploy previous version
```
Always have:
- Previous version images tagged
- Database backups
- Configuration backups
## Post-Deployment Checklist
- [ ] Application accessible via HTTPS
- [ ] SSL certificates valid
- [ ] All services healthy
- [ ] Database migrations completed
- [ ] Monitoring configured
- [ ] Backups scheduled
- [ ] Alerts configured
- [ ] Team has access
- [ ] Documentation updated
- [ ] Runbooks created
## Getting Help
- **Full Guide**: See `docs/K8S-MIGRATION-GUIDE.md`
- **Checklist**: See `docs/MIGRATION-CHECKLIST.md`
- **MicroK8s**: https://microk8s.io/docs
- **Kubernetes**: https://kubernetes.io/docs
## Estimated Timeline
- **VPS Setup**: 30-60 minutes
- **Configuration Updates**: 30-60 minutes
- **Image Build & Push**: 20-40 minutes
- **Deployment**: 15-30 minutes
- **Verification & Testing**: 30-60 minutes
- **Total**: 2-4 hours (first time)
With experience: ~1 hour for updates/redeployments
## Next Steps
1. Read through the full migration guide
2. Provision your VPS
3. Update configuration files
4. Test locally first
5. Deploy to production
6. Monitor and optimize
Good luck! 🚀
