Docker Node Alpine Image Build Fails on node-gyp

Also stated in my post update, here’s the Dockerfile I used to get things working:

FROM node:8.12-alpine
RUN apk add g++ make py3-pip
EXPOSE 8080
RUN mkdir /app
WORKDIR /app
COPY . /app
RUN npm install
CMD ["npm", "start"]

If your requirements demand your image minimize space, consider installing necessary packages with RUN apk add --no-cache --virtual [package-list] (instead of apk add [package-list]) and afterward clearing the cache in the image with RUN apk del .gyp.
