dockerfile, docker-compose, and init.sh

[mabushey]

I made a docker config to automatically have my site in a container. I'd be happy to provide a PR, or you can take what I have here:

cat Dockerfile

FROM ubuntu:latest

WORKDIR /root

RUN apt-get update && apt-get install -y vim curl git && rm -rf /var/lib/apt

RUN curl -fsSL https://developer.fermyon.com/downloads/install.sh | bash && mv ./spin /usr/local/bin/

EXPOSE 3000
COPY ./init.sh /root/init.sh
