# Kubernetes Deployment Example for CMS API

## 🔐 ایجاد Secrets

### برای Staging:

```bash
kubectl create secret generic cms-secrets \
  --from-literal=db-connection="Data Source=STAGING_SERVER;Initial Catalog=Foursat_Staging;User ID=sa;Password=STAGING_PASSWORD;MultipleActiveResultSets=True;Encrypt=False" \
  --from-literal=jwt-key="YOUR_STAGING_JWT_KEY" \
  --from-literal=kavenegar-key="YOUR_STAGING_KAVENEGAR_KEY" \
  --from-literal=daya-key="YOUR_STAGING_DAYA_KEY" \
  --from-literal=chatika-key="YOUR_STAGING_CHATIKA_KEY" \
  --from-literal=sentry-dsn="YOUR_STAGING_SENTRY_DSN" \
  --from-literal=slack-webhook="YOUR_STAGING_SLACK_WEBHOOK" \
  --from-literal=seq-key="YOUR_STAGING_SEQ_KEY" \
  --namespace=staging
```

### برای Production:

```bash
kubectl create secret generic cms-secrets \
  --from-literal=db-connection="Data Source=PRODUCTION_SERVER;Initial Catalog=Foursat;User ID=sa;Password=PRODUCTION_PASSWORD;MultipleActiveResultSets=True;Encrypt=True" \
  --from-literal=jwt-key="YOUR_PRODUCTION_JWT_KEY" \
  --from-literal=kavenegar-key="YOUR_PRODUCTION_KAVENEGAR_KEY" \
  --from-literal=daya-key="YOUR_PRODUCTION_DAYA_KEY" \
  --from-literal=chatika-key="YOUR_PRODUCTION_CHATIKA_KEY" \
  --from-literal=sentry-dsn="YOUR_PRODUCTION_SENTRY_DSN" \
  --from-literal=slack-webhook="YOUR_PRODUCTION_SLACK_WEBHOOK" \
  --from-literal=seq-key="YOUR_PRODUCTION_SEQ_KEY" \
  --from-literal=smtp-username="production@domain.com" \
  --from-literal=smtp-password="YOUR_SMTP_PASSWORD" \
  --namespace=production

## 🔄 CI/CD Integration

### GitLab CI Example:

```yaml
stages:
  - build
  - deploy-staging
  - deploy-production

variables:
  DOCKER_REGISTRY: your-registry.azurecr.io
  IMAGE_NAME: cms-api

build:
  stage: build
  script:
    - docker build -t $DOCKER_REGISTRY/$IMAGE_NAME:$CI_COMMIT_SHA .
    - docker push $DOCKER_REGISTRY/$IMAGE_NAME:$CI_COMMIT_SHA

deploy-staging:
  stage: deploy-staging
  only:
    - kub-stage
  script:
    - kubectl set image deployment/cms-api cms=$DOCKER_REGISTRY/$IMAGE_NAME:$CI_COMMIT_SHA -n staging
    - kubectl rollout status deployment/cms-api -n staging

deploy-production:
  stage: deploy-production
  only:
    - production
  when: manual  # نیاز به تأیید دستی
  script:
    - kubectl set image deployment/cms-api cms=$DOCKER_REGISTRY/$IMAGE_NAME:$CI_COMMIT_SHA -n production
    - kubectl rollout status deployment/cms-api -n production
```

## 📋 Monitoring

### Check deployment status:
```bash
kubectl get deployments -n staging
kubectl get pods -n staging -l app=cms-api
kubectl describe pod <pod-name> -n staging
```

### View logs:
```bash
kubectl logs -f deployment/cms-api -n staging
kubectl logs --tail=100 deployment/cms-api -n production
```

### Check configuration:
```bash
kubectl exec -it <pod-name> -n staging -- env | grep ASPNETCORE
```
