curl works but docker search doesnt work

[prashantladha]

Behind corporate firewall, I am trying "docker search" through the proxy server on a Windows 7 Docker Quickstart Terminal.

First set the proxy server details
export HTTP_PROXY="http://{REPLACE-WINDOWS-DOMAIN-NAME}{REPLACE-WINDOWS-USER-NAME}:{REPLACE-WINDOWS-PASSWORD}@{REPLACE-PROXY-SERVER}:{REPLACE-PROXY-PORT}/"
export HTTPS_PROXY="https://{REPLACE-WINDOWS-DOMAIN-NAME}{REPLACE-WINDOWS-USER-NAME}:{REPLACE-WINDOWS-PASSWORD}@{REPLACE-PROXY-SERVER}:{REPLACE-PROXY-PORT}/"
export NO_PROXY="192.168.99.100"

Error response from daemon: Get https://index.docker.io/v1/search?q=spark: dial
tcp 52.22.146.88:443: i/o timeout
