Lab 3.2. Grow the Cluster // Impossible to list token

Hello,

Somebody can help me !
When i execute the command to list the token, i receive error below:

~$ sudo kubeadm token list
failed to list bootstrap tokens: Get "https://ubuntu-master:6443/api/v1/namespaces/kube-system/secrets?fieldSelector=type=bootstrap.kubernetes.io/token": x509: certificate signed by unknown authority (possibly because of "crypto/rsa: verification error" while trying to verify candidate authority certificate "kubernetes")
To see the stack trace of this error execute with --v=5 or higher

  • Hi @zizibagnon,

    After the control-plane node init, did you manage to complete step 16? Are you using the most recent .kube/config file?

    Regards,
