I get Please enter Username when I try to deploy with a ServiceAccount, even I have set ClusterRole bindings - do you know why?

kubectl:

kubectl apply -f deployment.yaml

Role & binding:

kubectl create clusterrole tutorial-role \
               --verb=get,list,watch,create,update,patch,delete \
               --resource=deployments


kubectl create clusterrolebinding tutorial-binding \
             --clusterrole=tutorial-role \
             --serviceaccount=default:tutorial-service

Create config user:

TOKEN=$(kubectl describe secrets "$(kubectl describe serviceaccount tutorial-service | grep -i Tokens | awk '{print $2}')" | grep token: | awk '{print $2}')
kubectl config set-credentials tutorialuser --token=$TOKEN
kubectl config set-context sausercontext --cluster=<my-cluster> --user=tutorialuser
kubectl config use-context sausercontext --namespace=default

Deployment:

apiVersion: apps/v1
