给我一个svc的yaml文件示例

以下是一个基本的svc的yaml文件示例：

apiVersion: v1
kind: Service
metadata:
  name: nginx-svc
spec:
  selector:
    app: nginx
  ports:
  - name: http
    port: 80
    targetPort: 80
  type: ClusterIP

这个yaml文件定义了一个名为nginx-svc的Service对象，它将代理到包含标签app: nginx的Pod。该Service将在Kubernetes集群内部可用，并将容器的80端口映射到Service的80端口。该Service类型为ClusterIP，这意味着它将只在集群内部可访问。
