Lab 6.1. Why tokens from kubectl and busybox are different?

Gim6626

In Lab 6.1 is described the example of working with API and is said "We will deploy a simple Pod and view the resources. If you view the token file you will find it is the same value we put into the $token variable".

I followed instructions and got:

1. List of secrets

[13:03]user@ubuntu-vbox-k8s-master[~]$ kubectl get secrets --all-namespaces | grep default-tok
default           default-token-thgxz                              kubernetes.io/service-account-token   3      23d
kube-node-lease   default-token-64g6n                              kubernetes.io/service-account-token   3      23d
kube-public       default-token-f2b9g                              kubernetes.io/service-account-token   3      23d
kube-system       default-token-bzbps                              kubernetes.io/service-account-token   3      23d
low-usage-limit   default-token-vvf59                              kubernetes.io/service-account-token   3      30m

2. Got one secret (it is suggested to save token from here to $token variable)

[13:03]user@ubuntu-vbox-k8s-master[~]$ kubectl describe secret default-token-thgxz 
Name:         default-token-thgxz
Namespace:    default
Labels:       <none>
Annotations:  kubernetes.io/service-account.name: default
              kubernetes.io/service-account.uid: c155aaa0-0d80-4640-8d56-5fd4c2645380

Type:  kubernetes.io/service-account-token

3. Created busybox and checked token.

[13:05]user@ubuntu-vbox-k8s-master[~]$ kubectl run -i -t busybox --image=busybox --restart=Never
If you don't see a command prompt, try pressing enter.
/ # cat /var/run/secrets/kubernetes.io/serviceaccount/token

If you check tokens from point 2 and 3 - they are not the same as stated in lab.

What is wrong?

UPDATE - the beginning (before ".") in tokens are same, but remaining parts are different
