In order to setup a kuberntes cluster with kubeadm i had to go through our proxy, so before kubeadm init i export the no_proxy variables:

export no_proxy=ip_master,ip_node
export NO_PROXY=$no_proxy,ip_master,ip_node

Now i installed kubernetes dashboard following this but i got an error, service unavailable trying to reache ip_endpoint

So do i have to add the endpoint_ip to the no_porxy variable ? And if so how i add a range of ip_addresses to a runing cluster ?
