# are running the same version of Node.
FROM node:8.11.2
# The base node image sets a very verbose log level.
ENV NPM_CONFIG_LOGLEVEL warn
# Copy all local files into the image.
COPY . .
# install
RUN npm install
# Build for production.
RUN npm run build
# Set the command to start the node server.
CMD serve -s dist
# Tell Docker about the port we'll run on.
