K8s Certificate expired || error: You must be logged in to the server (Unauthorized)

[bergen876]

I've discovered that the k8s certs have expired which has resulted in Kubectl failing with the titled error

Could you consider updating the VMs box image with the updated certificate?

However, I have included the following steps that I used to work around the issue.

**** Work Around ***

Firstly reset rke2 by running

sudo rke2 server --cluster-reset

Remove old data from the etcd data directory if you get a error when running the cluster reset
sudo rm -rf /var/lib/rancher/rke2/server/db/etcd

The deployment uses rke2 as the Kubernetes manager. You will need to rotate the certificates there sudo rke2 certificate rotate

then restart rk2 by running

sudo systemctl restart rke2-server

Confirm that its started by sudo systemctl restart rke2-server

test that kubectl is working by running

sudo kubectl --kubeconfig /etc/rancher/rke2/rke2.yaml get pods --all-namespaces

Now to replace the Kubernetes configurations with the updated certificate information by modifying the Kube config file by updating it with the updated rke config

REPLACE vagrant@5g-spector:~/.kube$ config WITH /etc/rancher/rke2/rke2.yaml}

Test by running kubectl get pods -A
