docker in coreos usage
If the coreos is deployed behind a proxy, we can simply use following steps to make docker work:
1) copy the /usr/lib/systemd/system/docker.service to /etc/systemd/system/ directory
sudo cp /usr/lib/systemd/system/docker.service /etc/systemd/system/
2) edit the /etc/systemd/system/docker.service file and add
Environment="HTTP_PROXY=http://proxy.example.com:8080"
