[Rdo-list] nova-docker

Hey guys, I have installed an all-in-one openstack vm using packstack. Now i'm trying to install docker and get nova use it. I'm following this tuto https://wiki.openstack.org/wiki/Docker. When I try the docker search or the docker pull samalba/hipache commandes it gives me this error :2014/09/08 12:02:07 Get https://index.docker.io/v1/repositories/samalba/hipache/images: dial tcp 162.242.195.84:443: connection timed out . I think it's because of the proxy. Have anywone any idea on where I can set the proxy variable for the docker to use it? Thanks in advance. Sara
