Understanding your Dockerfile - New Dockerfile proposal

[ylacaute]

This issue is more an information request than a feature request. I don't understand why your Dockerfile is playing with git, gcc and so on, which is too complicated.

As you are building a ruby package, what about a Dockerfile like this :

FROM ruby:2.5.7-buster

RUN set -ex \
    && gem install hiptest-publisher

RUN mkdir /app
WORKDIR /app
VOLUME /app

ENTRYPOINT ["hiptest-publisher"]
