# Dockerfile for Threema Web, based on the nginx alpine image.
#
# WARNING: This Dockerfile does not include TLS termination. Make sure to run
#          the container behind a reverse proxy (e.g. Nginx) that does proper
#          TLS termination.

# First, build Threema Web in a node container

FROM node:10 AS builder
ENV NODE_ENV=production

WORKDIR /opt/threema-web/

RUN sed -i "s/SELF_HOSTED: [^,]*,/SELF_HOSTED: true,/g" src/config.ts

RUN npm ci
RUN npm run dist -- d

# Then, transfer the build artifacts to a minimal nginx container

FROM nginx:1.15-alpine

RUN rm /usr/share/nginx/html/*
