This project started off as a little bit of a joke... Nothing has changed.
MultiStagger allows you to run Docker multi-stage Dockerfile
s without having
to actually update docker. Simply call multistagger
infront of your docker
command.
Your Dockerfile
should have multiple stages for you to get the most benefit
out of it:
FROM alpine:latest as first
RUN echo "foo" > /file.txt
FROM alpine:latest as second
COPY --from=first /file.txt /test.txt
RUN cat /test.txt
This is useful if you are working somewhere that can't update docker to the latest but you want to have a forwards compatible way of implementing multistage builds today.
