Kubelet through a proxy server (http_proxy) on CoreOS?

[John Mattson]

Has anyone been able to get kubelet working through a proxy on CoreOS?  If so, how?  We've tried setting http_proxy's in both the kubelet service and early-docker server and they just seem to be ignored.

Thanks!

Hi John,

I've made it work at a customer environment behind corporate proxy.

CoreOS Kubelet wrapper runs kubelet thru rkt so apart from docker.service and early service changes to support docker pulls, you'll also need to write to '/etc/environment' file to set those variables; such as 

          http_proxy=http://172.16.1.11:3128
          https_proxy=http://172.16.1.11:3128
          no_proxy=172.16.1.11

for rkt.
