This example demonstrates a two-stage Docker build that containerizes an Angular 7 application for production deployment. The first stage uses `node:10.12` to copy the source code, run `npm install`, and execute `npm run build --prod` to compile the project. The second stage copies the resulting static files from `/app/dist/ng7-initial` into an `nginx:alpine` image, serving the built app via a lightweight web server. The Dockerfile leverages multi-stage builds and `COPY --from` to reduce the final image size by excluding build dependencies.
