Ingress gateway timing out while setting up sample app

Hi,
I’m not able to setup the ingress gateway for the book info app-

kubectl -n bookinfo samples/bookinfo/networking/bookinfo-gateway.yaml Error: unknown command "samples/bookinfo/networking/bookinfo-gateway.yaml" for "kubectl" Run 'kubectl --help' for usage. [ec2-user@ip-10-0-0-247 istio-1.6.2] kubectl -n bookinfo apply -f samples/bookinfo/networking/bookinfo-gateway.yaml
Error from server (Timeout): error when creating “samples/bookinfo/networking/bookinfo-gateway.yaml”: Timeout: request did not complete within requested timeout 30s
