Hello,

Few days ago, the last version of Rails was out.

I can see, with the following Dockerfile, that json support was dropped

************************************************************************
FROM fedora:latest
RUN dnf -y update
RUN dnf -y install @development-tools ruby{,-devel,gems} wget redhat-rpm-config zlib-devel libxml2-devel libxslt-devel
RUN wget -O /tmp/test.rb https://gist.githubusercontent.com/anonymous/5ddaa37e8ebcae88dd5e2f056b6b0d49/raw/1c253633ab0ce5411308368aa4ddd00b725e18fa/-
RUN gem install nokogiri -- --use-system-libraries
RUN gem update --system
RUN gem update
RUN gem install bundler
RUN ruby /tmp/test.rb
************************************************************************

Is there any steps to do to add json support or Ruby (2.3.1) on fedora (24).

Regards,
