sshpass -p "vagrant" ssh-copy-id -o StrictHostKeyChecking=no [email protected]
sshpass -p "vagrant" ssh-copy-id -o StrictHostKeyChecking=no [email protected]
sshpass -p "vagrant" ssh-copy-id -o StrictHostKeyChecking=no [email protected]

# copy to master node

scp [email protected]:~/.kube/config /tmp/kubeconfig/config

cp ~/.kube/config ~/.kube/config.bak

KUBECONFIG=~/.kube/config:/tmp/kubeconfig/config kubectl config view --flatten > /tmp/merge
cp /tmp/merge ~/.kube/config
