title: kubectl apply -f behind proxy
body: <p>I am able to install kubernetes using kubeadm method successfully. My environment is behind a proxy. I applied proxy to system, docker and I am able to pull images from Docker Hub without any issues. But at the last step where we have to install the pod network (like weave or flannel), its not able to connect via proxy. It gives a time out error. I am just checking to know if there is any command like curl -x http:// command for kubectl apply -f? Until I perform this step it says the master is NotReady.</p>
