Creating a Kubernetes Dashboard Token

Question

I'm trying to follow the instructions at https://github.com/kubernetes/dashboard/blob/master/docs/user/access-control/creating-sample-user.md to create a Kubernetes Dashboard token. However, when I run the specified command, I get an error

% kubectl -n kubernetes-dashboard create token admin-user
Error: must specify one of -f and -k

error: unknown command "token admin-user"
See 'kubectl create -h' for help and examples

If I jump back in the doc history, I see a different, more verbose command that I can run

% 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}}"

This seems to work OK and PR for the doc change mentions "version 1.24" but doesn't mention what piece of software version 1.24 refers to (kubectl? The Dashboard? Kuberenetes itself? kind? Something else?)

So what's going on with that first command? Why doesn't it work?

Answer 1

If your version is lower than 1.24, please run the following command.

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}}"

This works in my case. Thanks.
