[Compass-ci] Re: [PATCH v2 compass-ci 07/10] container/mail-robot: Dockerfile

+ENV DEBIAN_FRONTEND noninteractive

+RUN apt-get update && \

•       apt-get install -y git uuid-runtime curl ruby-listen ruby-json ruby-mail && \
  

•       gem install fileutils elasticsearch activesupport
  

separate apt-get and gem maybe better, write gem install in next line

RUN gem install fileutils elasticsearch activesupport

Thanks, Yinsi
