You can rebuild the entire thing without using the cache by doing a
docker build --no-cache -t user/image-name
To force a rerun starting at a specific line, you can pass an arg that is otherwise unused. Docker passes ARG values as environment variables to your RUN command, so changing an ARG is a change to the command which breaks the cache. It's not even necessary to define it yourself on the RUN line.

# bash
RUN sed -i s#/home/git:/bin/false#/home/git:/bin/bash# /etc/passwd
EXPOSE 8080 8082
CMD ["/usr/bin/supervisord"]
And then just run it with a unique arg:
docker build --build-arg INCUBATOR_VER=20160613.2 -t user/image-name .
To change the argument with every build, you can pass a timestamp as the arg:
docker build --build-arg INCUBATOR_VER=$(date +%Y%m%d-%H%M%S) -t user/image-name .
or:
docker build --build-arg INCUBATOR_VER=$(date +%s) -t user/image-name .
As an aside, I'd recommend the following changes to keep your layers smaller, the more you can merge the cleanup and delete steps on a single RUN command after the download and install, the smaller your final image will be. Otherwise your layers will include all the intermediate steps between the download and cleanup:
