Proxy authentication settings

I installed the stable version for Docker in my work PC and it is behind proxy. I configured the proxy details in the settings but when I try docker pull, i am getting error authentication required.

PS C:\Windows\system32> docker pull microsoft/nanoserver
Using default tag: latest
Pulling repository docker.io/microsoft/nanoserver
Error while pulling image: Get https://index.docker.io/v1/repositories/microsoft/nanoserver/images: Proxy Authentication Required

How do I configure proxy authentication? Thanks.

Hi, I am also facing the same issue. How did you resolve it?
