I have tried to deploy same manifest file to kubernetes cluster by using kubectl command that is working fine, but from Jenkins its failing.

Additionally one observation is that if in file only kind: Deployment is there, then its working but if i am adding further section for kind: Service which is for NodePort then its failing, while kind: Service with ClusterIP is working fine.

Manifest File :

apiVersion: apps/v1
kind: Deployment
metadata:
name: my_deployment
namespace: cloud
labels:
app: my_deployment
spec:
replicas: 1
selector:
matchLabels:
app: my_service
strategy:
type: Recreate
template:
