name: model-storage persistentVolumeClaim: claimName: qwen-model-pvc tolerations: - key: nvidia.com/gpu operator: Exists effect: NoSchedule3.4 服务暴露配置创建Service来暴露服务# service.yaml apiVersion: v1 kind: Service metadata: name: qwen-asr-service namespace: qwen-asr spec: selector: app: qwen-asr ports: - protocol: TCP port: 80 targetPort: 8000 type: LoadBalancer对于内部访问可以创建Ingress# ingress.yaml apiVersion: networking.k8s.io/v1 kind: Ingress metadata: name: qwen-asr-ingress namespace: qwen-asr annotations: nginx.ingress.kubernetes.io/proxy-body-size: 100m spec: rules: - host: asr.example.com http: paths: - path: / pathType: Prefix backend: service: name: qwen-asr-service port: number: 804. 部署与验证现在我们来实际部署并验证服务。4.1 执行部署依次应用所有配置文件# 应用所有配置 kubectl apply -f namespace.yaml kubectl apply -f pvc.yaml kubectl apply -f deployment.yaml kubectl apply -f service.yaml kubectl apply -f ingress.yaml # 查看部署状态 kubectl get all -n qwen-asr4.2 验证部署检查Pod状态和日志# 查看Pod状态 kubectl get pods -n qwen-asr -w # 查看Pod日志 kubectl logs -f deployment/qwen-asr-0.6b -n qwen-asr # 检查服务状态 kubectl get svc -n qwen-asr # 测试服务健康状态 SERVICE_IP$(kubectl get svc qwen-asr-service -n qwen-asr -o jsonpath{.status.loadBalancer.ingress[0].ip}) curl http://$SERVICE_IP/health4.3 模型下载初始化如果模型尚未下载可以创建初始化任务# init-job.yaml apiVersion: batch/v1 kind: Job metadata: name: model-downloader namespace: qwen-asr spec: template: spec: containers: -
