# Kubernetes Deployment for Auction Monitor
|
||||
|
||||
## Quick Start
|
||||
|
||||
### 1. Build and Push Docker Image
|
||||
|
||||
```bash
|
||||
# Build image
|
||||
docker build -t your-registry/auction-monitor:latest .
|
||||
|
||||
# Push to registry
|
||||
docker push your-registry/auction-monitor:latest
|
||||
```
|
||||
|
||||
### 2. Update deployment.yaml
|
||||
|
||||
Edit `deployment.yaml` and replace:
|
||||
- `image: auction-monitor:latest` with your image
|
||||
- `auction-monitor.yourdomain.com` with your domain
|
||||
|
||||
### 3. Deploy to Kubernetes
|
||||
|
||||
```bash
|
||||
# Apply all resources
|
||||
kubectl apply -f k8s/deployment.yaml
|
||||
|
||||
# Or apply individually
|
||||
kubectl apply -f k8s/namespace.yaml
|
||||
kubectl apply -f k8s/configmap.yaml
|
||||
kubectl apply -f k8s/secret.yaml
|
||||
kubectl apply -f k8s/deployment.yaml
|
||||
kubectl apply -f k8s/service.yaml
|
||||
kubectl apply -f k8s/ingress.yaml
|
||||
```
|
||||
|
||||
### 4. Verify Deployment
|
||||
|
||||
```bash
|
||||
# Check pods
|
||||
kubectl get pods -n auction-monitor
|
||||
|
||||
# Check services
|
||||
kubectl get svc -n auction-monitor
|
||||
|
||||
# Check ingress
|
||||
kubectl get ingress -n auction-monitor
|
||||
|
||||
# View logs
|
||||
kubectl logs -f deployment/auction-monitor -n auction-monitor
|
||||
```
|
||||
|
||||
### 5. Access Application
|
||||
|
||||
```bash
|
||||
# Port forward for local access
|
||||
kubectl port-forward svc/auction-monitor 8081:8081 -n auction-monitor
|
||||
|
||||
# Access API
|
||||
curl http://localhost:8081/api/monitor/status
|
||||
|
||||
# Access health check
|
||||
curl http://localhost:8081/health/live
|
||||
```
|
||||
|
||||
## Configuration
|
||||
|
||||
### ConfigMap
|
||||
|
||||
Edit workflow schedules in `configMap`:
|
||||
|
||||
```yaml
|
||||
data:
|
||||
AUCTION_WORKFLOW_SCRAPER_IMPORT_CRON: "0 */30 * * * ?" # Every 30 min
|
||||
AUCTION_WORKFLOW_IMAGE_PROCESSING_CRON: "0 0 * * * ?" # Every 1 hour
|
||||
AUCTION_WORKFLOW_BID_MONITORING_CRON: "0 */15 * * * ?" # Every 15 min
|
||||
AUCTION_WORKFLOW_CLOSING_ALERTS_CRON: "0 */5 * * * ?" # Every 5 min
|
||||
```
|
||||
|
||||
### Secrets
|
||||
|
||||
Update notification configuration:
|
||||
|
||||
```bash
|
||||
# Create secret
|
||||
kubectl create secret generic auction-secrets \
|
||||
--from-literal=notification-config='smtp:user@gmail.com:password:recipient@example.com' \
|
||||
-n auction-monitor
|
||||
|
||||
# Or edit existing
|
||||
kubectl edit secret auction-secrets -n auction-monitor
|
||||
```
|
||||
|
||||
## Scaling
|
||||
|
||||
### Manual Scaling
|
||||
|
||||
```bash
|
||||
# Scale to 3 replicas
|
||||
kubectl scale deployment auction-monitor --replicas=3 -n auction-monitor
|
||||
```
|
||||
|
||||
### Auto Scaling
|
||||
|
||||
HPA is configured in `deployment.yaml`:
|
||||
|
||||
```yaml
|
||||
spec:
|
||||
minReplicas: 1
|
||||
maxReplicas: 3
|
||||
metrics:
|
||||
- type: Resource
|
||||
resource:
|
||||
name: cpu
|
||||
target:
|
||||
averageUtilization: 80
|
||||
```
|
||||
|
||||
View HPA status:
|
||||
|
||||
```bash
|
||||
kubectl get hpa -n auction-monitor
|
||||
```
|
||||
|
||||
## Monitoring
|
||||
|
||||
### Health Checks
|
||||
|
||||
```bash
|
||||
# Liveness
|
||||
kubectl exec -it deployment/auction-monitor -n auction-monitor -- \
|
||||
wget -qO- http://localhost:8081/health/live
|
||||
|
||||
# Readiness
|
||||
kubectl exec -it deployment/auction-monitor -n auction-monitor -- \
|
||||
wget -qO- http://localhost:8081/health/ready
|
||||
```
|
||||
|
||||
### Logs
|
||||
|
||||
```bash
|
||||
# Follow logs
|
||||
kubectl logs -f deployment/auction-monitor -n auction-monitor
|
||||
|
||||
# Logs from all pods
|
||||
kubectl logs -f -l app=auction-monitor -n auction-monitor
|
||||
|
||||
# Previous pod logs
|
||||
kubectl logs deployment/auction-monitor --previous -n auction-monitor
|
||||
```
|
||||
|
||||
## Troubleshooting
|
||||
|
||||
### Pod not starting
|
||||
|
||||
```bash
|
||||
# Describe pod
|
||||
kubectl describe pod -l app=auction-monitor -n auction-monitor
|
||||
|
||||
# Check events
|
||||
kubectl get events -n auction-monitor --sort-by='.lastTimestamp'
|
||||
```
|
||||
|
||||
### Database issues
|
||||
|
||||
```bash
|
||||
# Check PVC
|
||||
kubectl get pvc -n auction-monitor
|
||||
|
||||
# Check volume mount
|
||||
kubectl exec -it deployment/auction-monitor -n auction-monitor -- ls -la /data
|
||||
```
|
||||
|
||||
### Network issues
|
||||
|
||||
```bash
|
||||
# Test service
|
||||
kubectl run -it --rm debug --image=busybox --restart=Never -n auction-monitor -- \
|
||||
wget -qO- http://auction-monitor:8081/health/live
|
||||
```
|
||||
|
||||
## Cleanup
|
||||
|
||||
```bash
|
||||
# Delete all resources
|
||||
kubectl delete -f k8s/deployment.yaml
|
||||
|
||||
# Or delete namespace (removes everything)
|
||||
kubectl delete namespace auction-monitor
|
||||
```
