Docker apt-get update fails

Can somebody help me get apt-get working in my docker container? Whenever I try running any apt-get command in my docker container, the command fails. I'm running Docker version 1.1.1, build bd609d2 on ubuntu 12.04. When I do $ sudo docker run -i -t ubuntu:14.04 /bin/bash # apt-get update I get errors saying > Could not resolve 'archive.ubuntu.com' I tried uncommenting the line below in /etc/default/docker > DOCKER_OPTS="--dns 8.8.8.8 --dns 8.8.4.4" but I still can't ping google.com > ping: unknown host I confirmed that the container is using the dns servers 8.8.8.8 and 8.8.4.4 > root@0baa87fc6322:/# cat /etc/resolv.conf > > nameserver 8.8.8.8 > > nameserver 8.8.4.4 and I'm able to ping both servers so I'm pretty sure that a firewall isn't just dropping my packets. Any help with this would be appreciated! Thanks!
