我想通过kubectl代理服务器访问我的Grafana Kubernetes服务，但由于某种原因，尽管我可以使其他服务正常工作，但它却无法工作。鉴于以下服务定义，为什么无法在http://localhost:8001/api/v1/proxy/namespaces/monitoring/services/grafana上使用？
grafana-service.yaml
apiVersion: v1
kind: Service

grafana-deployment.yaml
的翻译是grafana部署文件.yaml

当我访问上述URL时，出现的错误是"no endpoints available for service "grafana""，错误代码为503。
