This is an initial test at having a container build something from code in a mounted volume and delivering back the binary(-ies).
There is a high probability that this is of no use for anyone but myself.
It's based on the official gcc:4.9 image but with the bc package installed (needed to build the linux kernel which was my first test)
Invocation as follows:
docker run --rm -v "$(pwd)":/usr/src/linux -w /usr/src/linux mrmarkie/krnbld make
As said earlier, I'm just faffing about there is nothing to see here ;)
