Docker and IPv6 on Ubuntu 13.10 (Saucy Salamander)

After making myself familiar with Docker I wanted to use it on a more recent Ubuntu 13.10 release. I still didn’t install Docker natively on my pc, but use a Vagrant box to play with fresh releases. After downloading a fresh Ubuntu 13.10 image, creating a VirtualBox image and installing the current Docker release 0.8.0, I tried to use my other little toys CouchDB and Elasticsearch in Docker containers. Sadly, I couldn’t connect to the exposed ports anymore.
