Answer 1

NTML PROXY AND DOCKER 

If your company is behind MS Proxy Server that using the proprietary NTLM protocol.

You need to install **Cntlm** Authentication Proxy

After this SET the proxy in 
/etc/systemd/system/docker.service.d/http-proxy.conf) with the following format:

[Service]

Environment=“HTTP_PROXY=http://<>:3182”

In addition you can set in the .DockerFile
export http_proxy=http://<>:3182
export https_proxy=http://>:3182
export no_proxy=localhost,127.0.0.1,10.0.2.*

Followed by:
systemctl daemon-reload

systemctl restart docker

This Worked for me
