Add these steps inside any dockerfile:
ADD "https://raw.githubusercontent.com/yusuf-daglioglu/cc_scripts/master/release/cc_scripts.sh" "/this_path/is_inside_docker/cc_scripts.sh"
or if cc_scripts.sh file is being already downloaded on your local:
COPY "/this_path/is_inside/local_machine/cc_scripts.sh" "/this_path/is_inside_docker/cc_scripts.sh"
