Usage

docker run -it --rm -v <local project path>:/project throwtheswitch/madsciencelab[:tag]

But a better solution is a .bashrc function that automatically maps your pwd to project and sets the user and group to the current user. This avoids file creation as root when doing a ceedling:create .

ceed_here() { docker run --user $(id -u):$(id -g) -it --rm -v $(pwd):/project bd2357/ceedling_withgdb; }
