Kubernetes Dashboard access using config file Not enough data to create auth info structure.

Question

Answer 1

1 - Assuming one has followed the directions to setup the dashboard here. https://docs.aws.amazon.com/eks/latest/userguide/dashboard-tutorial.html

2 - And your normal kubectl access works from the command line (i.e. kubectl get services).

3 - And you are able to login manually to the Dashboard with the token (with kubectl -n kube-system describe secret ...), by using copy/paste.

4 - But now you want to use the "Kubeconfig" (instead of "Token") option to login to the Dashboard, for simplicity.

Solution:

• Find your user in the config file, that is used to access the cluster.
• The user is "kubernetes-admin" in this original posted question.
• Add a line with the "token:".
• Dont forget this is YAML, so use spaces, not tabs.

Here is what it should look like...

apiVersion: v1
clusters:
- cluster:
    certificate-authority-data: REDACTED
    server: https://kubemaster: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: REDACTED
    client-key-data: REDACTED
    token: PUT_YOUR_TOKEN_HERE_THAT_YOU_USED_TO_MANUALLY_LOGIN
