#hope you prepared the YAML file from the above steps NOW let's do the task

#create the namespace 

    kubectl create ns <namespace name from your question>

#create deployment

    kubectl apply -f <your-deploy.yaml > -n <namespace-name>

#check pods ( wait to running the pods)

     

    kubectl get pods -n <nameapace-name>

#now create-service 

    kubectl apply -f <your-service.yaml> -n <namespace-name>

#check the service 

    kubectl get service -n <namespace-name>

#Final verification 

#get the pod name from the below commands and replace it with the following command 

     kubectl get pods -n <namespace-name>

    

    

    kubectl exec <pod-name> -n <namespace-name>  -- curl -I http://localhost/
