kubectl - error: You must be logged in to the server

Question

I have configured OIDC with k8s installed using kubeadm. After the configuration, when I run the command kubectl [email protected] get nodes I get

error: You must be logged in to the server (the server has asked for the client to provide credentials (get nodes))

Can someone please help me with this?

Answer 1

I use kubectl [email protected] get nodes and it works. Earlier I was using the parameter --user instead of --username.

Creighton

--user is the correct parameter. --username is ignored, which means you may have been falling back to a default user that does not use oidc. – Alexaalexander

Answer 2

Your password is probably missing.

I have added the client_id, client_secret, id_token and refresh token to my /.kube/config file. Where do i need to add my password? Could you please let me know. It would be really helpful – Creighton

Sorry, I'm not an expert with kub, (but in openshift you should log with user, passwd) but --password="": might help. Please refer to: kubernetes-v1-4.github.io/docs/user-guide/kubectl/… – Hanako

Cloud you please tell me if i can add a role with the user and the password with K8S? – Creighton

Should the user be explicitly registered for this? I meant to ask if kubectl config set-context and set-credentials is required for this. – Creighton
