Background: I have setup a ServiceAccount and spinnaker-role-binding in the default namespace. Created the spinnaker namespace for Kubernetes. Deployed services on port 9000 and 8084.

NAME                   TYPE           CLUSTER-IP      EXTERNAL-IP   PORT(S)          AGE
service/spin-deck-np   LoadBalancer    hidden          <pending>     9000:31295/TCP   9m39s
service/spin-gate-np   LoadBalancer    hidden          <pending>     8084:32161/TCP   9m39s

Created halyard deployment in the default namespace and configured hal inside it.

Problem: When I run the hal deploy apply command then I am getting below error

Problems in Global:

Used below commands in hal to interact with kubernetes

kubectl config set-cluster default --server=https://kubernetes.default --certificate-authority=/var/run/secrets/kubernetes.io/serviceaccount/ca.crt
kubectl config set-context default --cluster=default
token=$(cat /var/run/secrets/kubernetes.io/serviceaccount/token)
kubectl config set-credentials user --token=$token
kubectl config set-context default --user=user
kubectl config use-context default

How could I resolve the error for spinnaker deployment?

Thank you
