How do I build an Ubuntu/Ruby image that also contains foreman?

Question

I want to build a Docker Ubuntu image with Ruby 2.3.8 and loaded with foreman. I constructed this Dockerfile

# sshd
#
# VERSION               0.0.1

FROM     drecom/ubuntu-base:latest

WORKDIR /myapp
COPY . .
RUN cd /myapp
RUN bin/bundle install

RUN apt-get install -y ruby-foreman

RUN foreman start

However upon running my Docker build command, (docker build -t my_image .), my container fails to even install foreman. Not sure if I’m using the right package but here’s the output …

 => ERROR [10/11] RUN apt-get install -y ruby-foreman                                                        7.1s

What’s the proper way to add foreman to the container and start it?
