Doesn't use API; needs root; doesn't work with current version of docker

[dagelf]

The docker binary exposes all the functions needed to do this without root access and without direct access to the docker paths. The current approach doesn't seem to be portable. Why can't the docker export command be used?

Your README is missing some vital information. Such as that you need to create an lxc config file inside your container root - I'm not sure if that is the best place...

It was created 4 years ago, just for fun, to get some knowledge of docker images and how to run using plain lxc.

Certainly, it won't work on current releases.
