ohif-viewer/Dockerfile

# syntax=docker/dockerfile:1.7-labs
# This dockerfile is used to publish the `ohif/app` image on dockerhub.
#
# It's a good example of how to build our static application and package it
# with a web server capable of hosting it as static content.
#
# docker build
# --------------
# If you would like to use this dockerfile to build and tag an image, make sure
# you set the context to the project's root directory:
# https://docs.docker.com/engine/reference/commandline/build/
#
#
# SUMMARY
# --------------
# This dockerfile has two stages:
#
# 1. Building the React application for production
# 2. Setting up our Nginx (Alpine Linux) image w/ step one's output
#


# Stage 1: Build the application
# docker build -t ohif/viewer:latest .
# Copy Files

# Copy package manifests for install caching. preinstall.js is included because
# the root package.json's "preinstall" lifecycle script (node preinstall.js)
# runs during `pnpm install` below -- before the full source is copied -- so the
# script file must already be present or install fails with MODULE_NOT_FOUND.
COPY package.json pnpm-lock.yaml pnpm-workspace.yaml .npmrc preinstall.js ./
COPY --parents ./extensions/*/package.json ./modes/*/package.json ./platform/*/package.json ./
# Run the install before copying the rest of the files.
# Keep --no-frozen-lockfile here (unlike CI): .dockerignore excludes
# platform/docs, so the lockfile's docs importer has no manifest in the build
# context and a frozen install would fail. pnpm reconciles (drops docs) instead.
