I am behind a proxy server and following the "Kubernetes Installation with Vagrant & CoreOS" steps listed here: https://coreos.com/kubernetes/docs/latest/kubernetes-on-vagrant.html
After finalizing the install, when I run
$ kubectl get nodesI get the error.
Unable to connect to the server: Service Unavailablee1, c1, and w1 are up and I can issue $vagrant ssh each of them.
when I check the w1, I have seen docker service was not running with the error listed below.

I am guessing that problem is because of I am behind the proxy. Before running the install steps I issue the commands
$export "HTTP_PROXY=http://http-proxy.xxxxxx.com:8080"
$export "HTTPS_PROXY=http://http-proxy.xxxxxx.com:8080"
$export "http_proxy=http://http-proxy.xxxxxx.com:8080"
$export "https_proxy=http://http-proxy.xxxxxx.com:8080"Do you know if this is enough for the installation behind proxy or do I need to add proxy settings to somewhere else.
Thank you in advance, turgos
The variables you're exporting are valid only in your current shell session, they are not available to your flannel systemd unit.
Create the following drop-in inside the systemd unit directory, and then reload the daemon with systemctl daemon-reload, it should fix your issue with flannel:
/etc/systemd/system/flannel.service.d/proxy.conf:
[Service]
Environment="HTTP_PROXY=http://http-proxy.xxx:8080"
Environment="...A similar example is available in the CoreOS documentation: Customizing Docker
