kubernetes lost ~/.kube/config

Question

Unfortunately I lost my local

~/.kube/config

where I had configuration for my namespace.

Is there a way to get this config if I have access to master nodes?

Thanks in advance

I believe you're using kubeadm to start your kubernetes cluster, you can generate the new kubeconfig file using following command:

kubeadm alpha phase kubeconfig admin --kubeconfig-dir /etc/kubernetes --cert-dir /etc/kubernetes/pki

This will generate a new config file in /etc/kubernetes/admin.conf. Then you can copy the file in following way:

mkdir -p $HOME/.kube
sudo cp -i /etc/kubernetes/admin.conf $HOME/.kube/config
sudo chown $(id -u):$(id -g) $HOME/.kube/config
