I am learning kubernetes ing GCP. I was trying out steps given in this tutorial.While doing deployment to cluster , we are doing

kubectl run gcp-spring-app --image=gcr.io/secondproject-275119/gcp-app-image --port=9080

which gives below error

kubectl run --generator=deployment/apps.v1 is DEPRECATED and will be removed in a future version. Use kubectl run --generator=run-pod/v1 or kubectl create instead.
deployment.apps/gcp-spring-app created

Upon searching the error i got that we should use --generator=run-pod/v1 and command look like this now

kubectl run --generator=run-pod/v1 gcp-spring-app --image=gcr.io/secondproject-275119/gcp-app-image --port=9080

It is actually working , but now when I do kubectl get pods, I am seeing multiple pods instead of one.Like below

NAME                              READY   STATUS    RESTARTS   AGE
gcp-spring-app                    1/1     Running   0          36s
gcp-spring-app-67767bd649-jvg9h   1/1     Running   0          4m55s

Can anybody explain why these two got created as I need one also if I should tweak the command to get only one.
