TL;DR Use Dockerfile.distroless or Dockerfile.alpine-production

Demonstrates various approaches to building production grade docker images to deploy services written in Typescript.

Comparison of approaches

Filename	Approach	Size
Dockerfile	Simple approach using Node docker image with source and build artifacts left in container	1.03GB
Dockerfile.alpine	Use Alpine linux variant of Node Docker image	256MB
Dockerfile.alpine-production	Use Alpine linux with build step separated from production (production image only contains build artifacts)	177MB
Dockerfile.distroless	Use distroless image for production stage (potential security improvements)	163MB

If you'd like to build all the images to compare yourself just run ./build-all.sh.
