# News API Kubernetes Deployment
|
||||
|
||||
## Overview
|
||||
Multi-language news articles REST API service for Kubernetes deployment.
|
||||
|
||||
## Features
|
||||
- **9 Language Support**: ko, en, zh_cn, zh_tw, ja, fr, de, es, it
|
||||
- **REST API**: FastAPI with async MongoDB
|
||||
- **Auto-scaling**: HPA based on CPU/Memory
|
||||
- **Health Checks**: Liveness and readiness probes
|
||||
|
||||
## Deployment
|
||||
|
||||
### Option 1: Local Kubernetes
|
||||
```bash
|
||||
# Build Docker image
|
||||
docker build -t site11/news-api:latest services/news-api/backend/
|
||||
|
||||
# Deploy to K8s
|
||||
kubectl apply -f k8s/news-api/news-api-deployment.yaml
|
||||
|
||||
# Check status
|
||||
kubectl -n site11-news get pods
|
||||
```
|
||||
|
||||
### Option 2: Docker Hub
|
||||
```bash
|
||||
# Set Docker Hub user
|
||||
export DOCKER_HUB_USER=your-username
|
||||
|
||||
# Build and push
|
||||
docker build -t ${DOCKER_HUB_USER}/news-api:latest services/news-api/backend/
|
||||
docker push ${DOCKER_HUB_USER}/news-api:latest
|
||||
|
||||
# Deploy
|
||||
envsubst < k8s/news-api/news-api-dockerhub.yaml | kubectl apply -f -
|
||||
```
|
||||
|
||||
### Option 3: Kind Cluster
|
||||
```bash
|
||||
# Build image
|
||||
docker build -t site11/news-api:latest services/news-api/backend/
|
||||
|
||||
# Load to Kind
|
||||
kind load docker-image site11/news-api:latest --name site11-cluster
|
||||
|
||||
# Deploy
|
||||
kubectl apply -f k8s/news-api/news-api-deployment.yaml
|
||||
```
|
||||
|
||||
## API Endpoints
|
||||
|
||||
### Get Articles List
|
||||
```bash
|
||||
GET /api/v1/{language}/articles?page=1&page_size=20&category=tech
|
||||
```
|
||||
|
||||
### Get Latest Articles
|
||||
```bash
|
||||
GET /api/v1/{language}/articles/latest?limit=10
|
||||
```
|
||||
|
||||
### Search Articles
|
||||
```bash
|
||||
GET /api/v1/{language}/articles/search?q=keyword&page=1
|
||||
```
|
||||
|
||||
### Get Article by ID
|
||||
```bash
|
||||
GET /api/v1/{language}/articles/{article_id}
|
||||
```
|
||||
|
||||
### Get Categories
|
||||
```bash
|
||||
GET /api/v1/{language}/categories
|
||||
```
|
||||
|
||||
## Testing
|
||||
|
||||
### Port Forward
|
||||
```bash
|
||||
kubectl -n site11-news port-forward svc/news-api-service 8050:8000
|
||||
```
|
||||
|
||||
### Test API
|
||||
```bash
|
||||
# Health check
|
||||
curl http://localhost:8050/health
|
||||
|
||||
# Get Korean articles
|
||||
curl http://localhost:8050/api/v1/ko/articles
|
||||
|
||||
# Get latest English articles
|
||||
curl http://localhost:8050/api/v1/en/articles/latest?limit=5
|
||||
|
||||
# Search Japanese articles
|
||||
curl "http://localhost:8050/api/v1/ja/articles/search?q=AI"
|
||||
```
|
||||
|
||||
## Monitoring
|
||||
|
||||
### View Pods
|
||||
```bash
|
||||
kubectl -n site11-news get pods -w
|
||||
```
|
||||
|
||||
### View Logs
|
||||
```bash
|
||||
kubectl -n site11-news logs -f deployment/news-api
|
||||
```
|
||||
|
||||
### Check HPA
|
||||
```bash
|
||||
kubectl -n site11-news get hpa
|
||||
```
|
||||
|
||||
### Describe Service
|
||||
```bash
|
||||
kubectl -n site11-news describe svc news-api-service
|
||||
```
|
||||
|
||||
## Scaling
|
||||
|
||||
### Manual Scaling
|
||||
```bash
|
||||
# Scale up
|
||||
kubectl -n site11-news scale deployment news-api --replicas=5
|
||||
|
||||
# Scale down
|
||||
kubectl -n site11-news scale deployment news-api --replicas=2
|
||||
```
|
||||
|
||||
### Auto-scaling
|
||||
HPA automatically scales between 2-10 replicas based on:
|
||||
- CPU usage: 70% threshold
|
||||
- Memory usage: 80% threshold
|
||||
|
||||
## Cleanup
|
||||
|
||||
```bash
|
||||
# Delete all resources
|
||||
kubectl delete namespace site11-news
|
||||
```
|
||||
|
||||
## Troubleshooting
|
||||
|
||||
### Issue: ImagePullBackOff
|
||||
**Solution**: Use Docker Hub deployment or load image to Kind
|
||||
|
||||
### Issue: MongoDB Connection Failed
|
||||
**Solution**: Ensure MongoDB is running at `host.docker.internal:27017`
|
||||
|
||||
### Issue: No Articles Returned
|
||||
**Solution**: Check if articles exist in MongoDB collections
|
||||
|
||||
### Issue: 404 on all endpoints
|
||||
**Solution**: Verify correct namespace and service name in port-forward
