I'm trying to validate Kubernetes cluster using kops validate command, but it throws this error:
Error: Validation failed: cannot load kubecfg settings for "demo.k8s.naveen.tk": context "demo.k8s.naveen.tk" does not exist
Did you run kops update cluster --name demo.k8s.naveen.tk --yes yet? That command should automatically create the context.
You can also run kops export kubecfg --name demo.k8s.naveen.tk --admin, which will create a temporary admin certificate.
