Revised onbuild images about docker-erlang-otp HOT 2 CLOSED

are you aware of https://github.com/docker-library/docs/pull/911/files it seems many users want to customize ONBUILD process but it doesn't have the flexibility

+The ONBUILD image variants are deprecated, and their usage is discouraged. For more details, see docker-library/official-images#2076.

I was keeping 19/onbuild/ directory only for travis-ci, but after I redesigned .travis-ci.yaml process the onbuild/ directory is no longer needed;

For your showed case, I agree it could be a good one, from above docker-library# the recommended way is we may document it as a good minimal example of using multi-stage build, it's just like for end users to copy all ONBUILD instructions

FROM erlang:19 as builder
# copy all ONBUILD instructions here

FROM ubuntu:16    # or from alpine:3.6
COPY --from=builder /opt/rel ...

Oh, weird, I was not aware. Then yea, your suggestion of it as a documentation piece is good.
