Dockerfile

[Techbrunch]

If someone wants to play with it, here is a barebone Dockerfile:

FROM debian

RUN apt update
RUN apt install -y libjson-perl libnet-dns-perl libnet-netmask-perl build-essential git
RUN git clone https://github.com/jschauma/spf/ && cd spf && make install

ENTRYPOINT [ "spf" ]

[jschauma]

Thanks - just added to the repository. :-)
