yes, copy… python is script, if there are some binaries, who knows… i would run the latest python version…always issues when u upgrade something…
the docker runtime is quite new compared to ubuntu 10… so no idea what will break.
you could ‘try’ by using docker volumes -v host_path:container_path (note that there are limitations on the root of the host_path), which would let you test without moving any of the app code.
