Not able to retrieve kubeapps dashboard api token

# Disable swap

# sed -i '/swap/s/^\(.*\)$/#\1/g' /etc/fstab

# 有效的

# wget https://raw.githubusercontent.com/kubernetes/dashboard/v2.2.0/aio/deploy/recommended.yaml

# kubectl -n kubernetes-dashboard create token admin-user

# kubectl label node rh86-worker1 node-role.kubernetes.io/worker=worker 

# kubectl label node rh86-worker1 node-role.kubernetes.io/worker=worker --overwrite

# 有 bug

# kubectl -n kubernetes-dashboard get secret $(kubectl -n kubernetes-dashboard get sa/admin-user -o jsonpath="{.secrets[0].name}") -o go-template="{{.data.token | base64decode}}"
