I advise you to use an alpine base image instead, it would make it lighter and more powerful 😄

Whaou I just realized this PR was open on 2017 ^^
I suggest this Dockerfile for 2019

FROM node:10.15.1-alpine # LTS

ENV NODE_ENV production
ENV PORT 3000

WORKDIR /app
RUN apk add --update --no-cache git && \
	git clone --single-branch --depth=1 https://github.com/idoco/intergram.git && \
	cd intergram && \
	npm install && \
	npm run build # maybe useless due to postinstall script

EXPOSE 3000

WORKDIR /app/intergram
ENTRYPOINT ["npm", "start"]
