Jenkins Service File

{ apiVersion: v1
kind: Service
metadata: 
  name: jenkins
spec: 
  ports: 
     - port: 8080
       protocol: TCP
       targetPort: 8080
       nodePort: 30000
  externalIPs:

 }

Background: I want to access dashboard on Kubernetes, this service is running on Kubernetes cluster, I cant find more documentation about how to access the jenkins dashboard. - Do I need more configuration in the service file? - Are there any alternatives or way to accomplish this?
