Answer 1

You can download it from its repo on github and call the binary within your container:

RUN curl -L https://github.com/wkhtmltopdf/wkhtmltopdf/releases/download/0.12.4/wkhtmltox-0.12.4_linux-generic-amd64.tar.xz | tar -xJ

The above downloads and extracts it in your active working directory in your docker image.
