This document discusses multi-stage builds in Docker, the Moby project for assembling container-based systems, and LinuxKit for building secure, portable container subsystems. It introduces multi-stage builds as a way to create smaller container images using multiple build stages in a single Dockerfile. It also mentions the Moby project's goal of integrating container components and LinuxKit's aim to provide a "RedisOS" for Mac, Windows, and other platforms using HyperKit.

2. my container images are too big!

3. Introducing
multi-stage builds

4. a new way to build smaller images as of Docker 17.05
first/build stage: complete build
environment
second/final stage: smallest
possible artifact image

5. # Dockerfile
# build stage
FROM buildbase as build
...
...
...
# production ready stage
FROM runbase
...
COPY --from=build
