# This image will be published as dspace/dspace-angular:$DSPACE_VERSION-dist
# See https://github.com/DSpace/dspace-angular/tree/main/docker for usage details

# Test build:
# docker build -f Dockerfile.dist -t dspace/dspace-angular:latest-dist .

# Step 1 - Build code for production
FROM docker.io/node:22-alpine AS build

# Ensure Python and other build tools are available
# These are needed to install some node modules, especially on linux/arm64
RUN apk --no-cache add python3 make g++

WORKDIR /app
# Copy over package files first, so this layer will only be rebuilt if those files change.
COPY package.json package-lock.json ./
# NOTE: "ci" = clean install from package files
RUN npm ci

# Around 4GB of memory is required to build the app for production.
# This default setting can be overridden as needed in your shell, via an env file or in docker-compose.
# See Docker environment var precedence: https://docs.docker.com/compose/environment-variables/envvars-precedence/

RUN npm run build:prod

# Step 2 - Start up UI via PM2
FROM docker.io/node:22-alpine

# Install PM2
RUN npm install --global pm2

# Copy pre-built code from build image
COPY --chown=node:node --from=build /app/dist /app/dist
# Copy configs and PM2 startup script from local machine
COPY --chown=node:node config /app/config
COPY --chown=node:node docker/dspace-ui.json /app/dspace-ui.json

# Start up UI in PM2 in production mode
WORKDIR /app

# On startup, run start the DSpace UI in PM2
ENTRYPOINT [ "pm2-runtime", "start", "dspace-ui.json" ]
# By default, pass param that specifies to use JSON format logs.
