I'm trying to install rails on a docker container. However the OS inside docker cannot seem to connect to the internet. I get this error message on the base (just apt-get wasn't able to connect to the internet).

sudo: unable to resolve host e62b9fa31bb9

Err http://archive.ubuntu.com quantal Release.gpg

W: Some index files failed to download. They have been ignored, or old ones used instead.

I've had this issue since docker 0.1 to 0.3. Running on either the host machine or in vmware. (Virtualbox does not have this issue but sometimes the kernel segfaults within the container.)
