For Docker to use your build arguments, you need to specify them by name in your Dockerfile as an ARG. Once you do that, these variables will be available for you to use as arguments.

FROM kalilinux/kali-rolling

# Add build args
ARG aws_access_key_id
ARG aws_secret_access_key
ARG default_region
ARG bucket


WORKDIR /attack

COPY . /attack
RUN ls
RUN chmod +x attack.sh
RUN ./attack.sh $aws_access_key_id $aws_secret_access_key $default_region $bucket

I'm not sure this will do what you want it to do since the script will be run during build time. However, it will pass your arguments from the docker build command to the parameters of attack.sh.
