Docker failed to build on Rails bundle Install rake - ruby-on-rails

Question

I use Docker for Windows which I use to run a Image for a Rails(v5) App.
When I do docker-compose build I get this error. I don't known where to look to debug and/or resolve this.
Here is my Dockerfile:
FROM ruby:2.3.3-slim
RUN apt-get update && apt-get install -y build-essential
RUN apt-get install -y libmysqlclient-dev
RUN apt-get install -y mysql-client
RUN apt-get install -y libmagickwand-dev imagemagick
RUN apt-get install -y curl
RUN curl -sL https://deb.nodesource.com/setup_6.x | bash -
RUN apt-get install -y nodejs
RUN apt-get install -y git
#RUN npm install -g phantomjs
RUN gem update --system
RUN mkdir -p /MyImage
WORKDIR /MyImage
COPY Gemfile Gemfile
COPY Gemfile.lock Gemfile.lock
RUN gem install bundler
RUN bundle install
COPY package.json package.json
RUN npm update
RUN npm install
COPY . /MyImage
CMD [ "foreman", "start" ]
Here is a log if my error:
Step 15/20 : RUN bundle install

Installing rake 12.1.0
Errno::ENOENT: No such file or directory # rb_sysopen -

An error occurred while installing rake (12.1.0), and Bundler cannot continue.
Make sure that `gem install rake -v '12.1.0'` succeeds before bundling.
In Gemfile:
autonumeric-rails was resolved to 2.0.0.1, which depends on
jquery-rails was resolved to 4.3.1, which depends on
railties was resolved to 5.0.6, which depends on
rake
ERROR: Service 'MyImage' failed to build: The command '/bin/sh -c bundle install' returned a non-zero code: 5
But when I do gem install rake -v '12.1.0' directly into the shell of my container, everything install just fine.

Answer 1

Just try to install rake by yourself as described in the error message:
gem install rake -v '12.1.0'
To debug:
Comment out all lines in your Dockerfile starting from RUN bundle install and to end;
Then run docker build -t test:0.0 .;
To start interactive session: docker run -it test:0.0 /bin/bash;
Try to execute gem install rake -v '12.1.0' manually...
