docker build fails

[HanXHX]

Hi,

I tried to build a container with your Dockerfile

Tested branch: new-scoring, latest commit
Reproducible: yes

See build message:

Step 9/21 : RUN echo "gem: --no-test --no-document" > /etc/gemrc && 	gem install bundler && 	bundle install --deployment --without development test
 ---> Running in dd5c8e4448aa
Successfully installed bundler-2.0.1
Parsing documentation for bundler-2.0.1
Installing ri documentation for bundler-2.0.1
Done installing documentation for bundler after 5 seconds
1 gem installed
Don't run Bundler as root. Bundler can ask for sudo if it is needed, and
installing your bundle as root will break this application for all non-root
users on this machine.
The --deployment flag requires a Gemfile.lock. Please make sure you have checked
your Gemfile.lock into version control before deploying.
The command '/bin/sh -c echo "gem: --no-test --no-document" > /etc/gemrc && 	gem install bundler && 	bundle install --deployment --without development test' returned a non-zero code: 16

Hello!

new-scoring branch is currently under heavy development and quite not usable.
Docker support is experimental and mostly development related (because of tedious old ruby & openssl dependencies).

Quickly looking, you don't have Gemfile.lock file, which is generated during development and currently not commited. Remove the --deployment flag and it may work.
