Docker, CentOS & a Proxy all walk into a pub

CentOS 7.1 behind SQUID Proxy.  Docker install using YUM.

docker info

FATA[0000] Get http:///var/run/docker.sock/v1.18/images/search?term=apache: dial unix /var/run/docker.sock: no such file or directory. Are you trying to connect to a TLS-enabled daemon without TLS?

Followed the official instructions @ which seemed to fix docker info but subsequent

docker search <name>

would fail with :

FATA[0127] Error response from daemon: Get dial tcp connection timed out

Tried setting the environment variable manually and also running the command inline

https_proxy=http://<server>:<port> docker search <name>

Stumbled across a blog suggesting adding environment variables to /etc/sysconfig/docker

 export HTTP_PROXY HTTPS_PROXY http_proxy https_proxy   

Problem fixed
