Multi-stage building with Docker

Docker supports a feature, where you can create multiple containers with a single dockerfile and at the same time share the contents between the containers. This feature gives you the possibility of having multi-stage builds and opens one significant spot for creating repeatable builds.

The idea behind it is simple, you can have multiple FROM statements inside the same Dockerfile. Each FROM statement can use different images, therefore defines it’s own dependencies and allows you to connect the containers from one base to the other by using COPY --from=0or COPY --from=previous-stage.

Version 5 is a completely re-done, its structure and mentality mimics the frameworks like Django, Flask or Express, which are small and provide you with basic functionality for web development. The rest is provided upon request by adding packages.
