Dockerfile not up to date

[almereyda]

In trying to reuse the existing Dockerfile, this was only possible after

1. following the instructions in https://flaviocopes.com/update-npm-dependencies/ on the source repository
2. removing the sudoroom-data symlink and replacing it with an empty folder Docker instructions broken by sudoroom-data symlink #75
3. copying settings.example.js to settings.js,
4. simplifying the build

which may be due to liberal use of Node 8 and straight updating of all packages in package.json

Is it worth for you to debug this occurrence?

[zyphlar]

I also tried running via docker directly and first got the contents of First Run, seemingly a lack of pug. Then I tried @almereyda's solution and had to add python and build-essential to node:8-stretch-slim in order to satisfy dependencies, but still hit a brick wall with the contents of Second Run which seems to be a fundamental compilation error/incompatibility that I'm not enough of a nodejs person to debug.

First Run

FROM node:8-stretch-slim
# Get prerequisites

RUN apt-get update && apt-get install -y \
  libcairo2-dev \
  man-db
# Put the (symlinked) db in here
RUN mkdir -p /usr/src/sudoroom-data
# Put the app in here
RUN mkdir -p /usr/src/app
WORKDIR /usr/src/app
# Get npm stuff
COPY package.json /usr/src/app/
RUN npm install
# Get everything else
COPY . /usr/src/app
# Expose the port we listen on
EXPOSE 80
# Run it
CMD [ "npm", "start" ]

Step 7/10 : RUN npm install
