Running on Mac OS High Sierra, I solved this by enabling Kubernetes built into Docker itself.

If this happens in GCP, the below most likely will resolve the issue:

gcloud container clusters get-credentials your-cluster --zone your-zone --project your-project

Similar to @sumitkau, I solved my problem with setting new kubelet config location using: kubectl --kubeconfig /etc/kubernetes/admin.conf get no You can also copy /etc/kubernetes/admin.conf to ~/.kube/config and it works, but I don't know that it's a good work or not!

I was trying to get status from remote system using ansible and I was facing same issue. I tried and it worked. kubectl --kubeconfig ./admin.conf get pods --all-namespaces -o wide

I have this issues. This solution work for me:

sudo cp /etc/kubernetes/admin.conf $HOME/
sudo chown $(id -u):$(id -g) $HOME/admin.conf
export KUBECONFIG=$HOME/admin.conf

If you don't have admin.conf, plz install kubeadm And then remove ~/.kube/cache

rm -rf ~/.kube/cache

Thanks to @mamirkhani. I solved this error. However I just found such info in "kubeadm init" output: Your Kubernetes master has initialized successfully! To start using your cluster, you need to run (as a regular user): sudo cp /etc/kubernetes/admin.conf $HOME/ sudo chown $(id -u):$(id -g) $HOME/admin.conf export KUBECONFIG=$HOME/admin.conf

I think this is the recommended solution.

Try using --server to specify your master: kubectl --server=16.187.189.90:8080 get pod -o wide
