I'm new to Kubernetes. With the help of Kubernetes documentation , I installed minikube(v0.24.1) and kubectl in my Windows machine. VirtualBox(Version 5.1.18) is also installed in my machine.

Before starting the minikube, i have executed set HTTP_PROXY=xx.xx.xx:8080 and set NO_PROXY=localhost,127.0.0.0/8,192.0.0.0/8 in Windows command prompt

Started minikube by passing Proxy Details :

C:\minikube>minikube start --memory 4096  --vm-driver=virtualbox --docker-env http_proxy=xx.xx.xx:8080  --docker-env https_proxy=xx.xx.xx:8080 --docker-env no_proxy=localhost,127.0.0.0/8,192.0.0.0/8 --cache-images=false

Kubectl is now configured to use the cluster.
Loading cached images from config file.

Error from Kubectl :

C:\minikube>kubectl version
