$ cat /etc/systemd/system/atomic-openshift-master-api.service 

ExecStart=/usr/bin/docker run --rm --privileged --net=host --name atomic-openshift-master-api -v /var/lib/origin:/var/lib/origin -v /var/run/docker.sock:/var/run/docker.sock -v /etc/origin:/etc/origin openshift3/ose start master api --config=${CONFIG_FILE} $OPTIONS


Systemd services created only accept  $OPTIONS 

In order for Proxy variables to get set for the node.controller,or api workaround using openshift-master-api as an example. 

ExecStart=/usr/bin/docker run --rm --privileged --net=host --name atomic-openshift-master-api -v /var/lib/origin:/var/lib/origin -v /var/run/docker.sock:/var/run/docker.sock -v /etc/origin:/etc/origin openshift3/ose start master api --config=${CONFIG_FILE} $OPTIONS  -e HTTP_PROXY=${HTTP_PROXY} -e HTTPS_PROXY=${HTTPS_PROXY}  -e NO_PROXY=${NO_PROXY}
