Quick Task 260329-x2a: Dockerfile and .dockerignore for Zauberwald

One-liner: Multi-stage Docker build (node:22-alpine) with Vite preview server on port 4173 and runtime config.json override via volume mount.

What Was Built

Dockerfile — Two-stage build:

• Stage 1 (build): node:22-alpine, installs all deps with npm ci, copies source, runs npm run build (tsc + vite build) producing dist/
• Stage 2 (serve): node:22-alpine, installs all deps again (needed for vite preview), copies dist/ and vite.config.ts from build stage, exposes port 4173, runs npm run preview

.dockerignore — Excludes node_modules, dist, .git, .planning, *.md, .biome, .claude, .agents from build context.

Usage

# Build the image
docker build -t zauberwald .

# Run with config.json mounted from host
docker run -v /path/to/config.json:/app/dist/config.json:ro -p 4173:4173 zauberwald

The app is then accessible at http://localhost:4173.

Key Decisions

• All project dependencies are devDependencies (vite, typescript, etc.). The serve stage must run npm ci (without --omit=dev) so that vite is available for npm run preview.
• public/config.json is intentionally NOT excluded from .dockerignore — it must be baked into dist/ during build. At runtime, users can override it by mounting their own config.json to /app/dist/config.json.
• vite.config.ts is copied into the serve stage because Vite reads it to apply the host: "0.0.0.0" and port: 4173 preview settings.

Deviations from Plan

None — plan executed exactly as written.
