I think you should be checking for namespace by typing: kubectl get ns and not kubectl config view (the config view command is used to view your --kubeconfig file).

Please see below:

controlplane ~ ✖ kubectl get namespaces 
NAME              STATUS   AGE
default           Active   25m
kube-node-lease   Active   25m
kube-public       Active   25m
kube-system       Active   25m

controlplane ~ ➜  kubectl config view 
apiVersion: v1
clusters:
- cluster:
    certificate-authority-data: DATA+OMITTED
    server: https://controlplane:6443
  name: kubernetes
contexts:
- context:
    cluster: kubernetes
    user: kubernetes-admin
  name: kubernetes-admin@kubernetes
current-context: kubernetes-admin@kubernetes
kind: Config
preferences: {}
users:
- name: kubernetes-admin
  user:
    client-certificate-data: DATA+OMITTED
    client-key-data: DATA+OMITTED

so what I think you should do is to actually create the namespace “vote” before running your deployment. Like so:

controlplane ~ ✖ kubectl create namespace vote
namespace/vote created

I hope that helps.
