Using production instructions in Dockerfile doesn't work

Hi,

In the Dockerfile it is instructed to use
RUN npm ci --only=production
instead of
RUN npm install
if we are building for production.

When I do this (API in project_prod.js configured to be a local deployment of the API service) I get the following error:

> bullet-train-frontend@1.3.0 dev /usr/src/app
> cross-env npm run env && node_modules/.bin/nodemon --watch server --ignore server/config/config.json --watch webpack --exec node ./server


> bullet-train-frontend@1.3.0 env /usr/src/app
> node ./bin/env.js

Using project_dev.js

Hi @julianwilkinson. You could use something like this for production:

FROM node:10

# Create app directory
WORKDIR /usr/src/app

# Bundle app source
COPY . .

# Install app dependencies
# A wildcard is used to ensure both package.json AND package-lock.json are copied
# where available (npm@5+)
COPY package*.json ./

ENV ENV prod
RUN npm i
RUN npm run env
RUN npm run bundle

EXPOSE 8080
CMD [ "npm", "run", "start" ]

This is in our private upstream repo so will be pushed to github soon
