I am trying to start minikube cluster in Ubuntu VM. I am behind the http proxy. I am getting the below error.
osboxes@osboxes:$ sudo minikube start --docker-env http_proxy=$http_proxy --docker-env https_proxy=$https_proxy

@javakishore Do you mind attaching the output of minikube logs when this failure happens?

[tstromberg]

While you have specified --docker-env overrides, you actually need to set the HTTP_PROXY and HTTPS_PROXY environment variables to tell minikube about your proxy, as per:

https://github.com/kubernetes/minikube/blob/master/docs/http_proxy.md

I've now updated the doc to mention this specific issue. Please let me know if this helps.
