DEPRECATED
This image is officially deprecated in favor of the standard ruby image, and will receive no further updates after 2016-12-31 (Dec 31, 2016). Please adjust your usage accordingly.
For most usages of this image, it was already not bringing in rails from this image, but actually from your project's Gemfile, so the only "value" being added here was the pre-installing of nodejs, mysql-client, postgresql-client, and sqlite3 for various uses of the rails framework.
For example, a Dockerfile similar to the following would be a good starting point for a Rails project using PostgreSQL:
FROM ruby:2.3
RUN apt-get update \
&& apt-get install -y --no-install-recommends \
postgresql-client \
&& rm -rf /var/lib/apt/lists/*
WORKDIR /usr/src/app
COPY Gemfile* ./
RUN bundle install
COPY . .
EXPOSE 3000
CMD ["rails", "server", "-b", "0.0.0.0"]About this Repo
