Custom Dockerfile to use local source code

Stephen,
Thank you for the prompt response. That is the dockerfile that have been using. Additionally, I have been using the fex image to test changes made to the source code locally. With that being said, With my current setup every time I want to create/test a new image, I have to push my changes to Github and use the dockerfile to clone from Github. I was wondering if there is a way to bypass the git clone config in the dockefile and replace it with the my local repo (source code)?
