Using Make and GCC from Docker to compile local source tree

Question

So I am experimenting with Docker and I am contemplating a possibility of compiling a source tree on my local machine, using gcc & make and some more dependent libraries from a Docker container running locally.

Is it even possible? If yes, how do I go about it?

It's possible. There's an official gcc image that does exactly that. There's a couple of example Dockerfiles on their dockerhub page, that will help you get started:

FROM gcc:4.9
COPY . /usr/src/myapp
WORKDIR /usr/src/myapp
RUN gcc -o myapp main.c
CMD ["./myapp"]

Or, without building an image:

$ docker run --rm -v "$PWD":/usr/src/myapp -w /usr/src/myapp gcc:4.9 gcc -o myapp myapp.c

what this does is - it creates a temporary (--rm) docker container, mounts the local folder as a volume (-v) compiles and exits, leaving only the resulting binary left.
