Rails Dockerコンテナのバンドルインストールに失敗しました

Question

ドッカーコンテナを配備する際に問題が発生しました。主にbundlerがinstallコマンドを実行できないためです。 bundle installをローカルでpassengerで実行するとうまくいくように見えますが、デプロイメント手順だけで宝石を設定する際に問題が発生します。

私は比較的新しいDockerです。私は自分自身をRailsという専門家と呼んでいません。つまり、私はこのようなことを（例えばDockerとの組み合わせで）正確にbundlerがこの全てを混乱させてしまうのを理解するのが難しいです。

私は乗客ドッカーのベースイメージを使用していますが、これは関連性があります。ここで

私Gemfileです：

gem 'doorkeeper' 
gem 'doorkeeper-jwt' 
gem 'aws-sdk-rails' 
gem 'rack-cors', :require => 'rack/cors' 
gem 'active_model_serializers', github: 'rails-api/active_model_serializers' 
gem 'passenger' 
gem 'rails', '4.2.6' 
gem 'rails-api' 
gem 'pg' 
gem 'devise' 
gem 'schema_plus' 
gem 'pusher' 
gem 'sdoc', '~> 0.4.0', group: :doc 

group :development, :test do 

    gem 'byebug' 
    gem 'web-console', '~> 2.0' 
    gem 'spring' 
    gem 'rspec-rails' 
    gem 'factory_girl_rails', '~> 4.0' 
    gem 'database_cleaner' 

end 

そして、ここでDockerfile（の一部）：

RUN mkdir /home/app/myapp 
WORKDIR /home/app/myapp 

COPY Gemfile /home/app/myapp/ 
COPY Gemfile.lock /home/app/myapp/ 
RUN chown -R app:app /home/app/myapp 
RUN sudo -u app bundle install --deployment --verbose --path vendor/cache 

ADD . /home/app/myapp 
RUN chown -R app:app /home/app/myapp 

私が展開しようとすると、私は次のエラーを取得します：

Message from application:

It looks like Bundler could not find a gem. Maybe you didn't install all the gems that this application needs. To install your gems, please run:

bundle install

If that didn't work, then the problem is probably caused by your application being run under a different environment than it's supposed to. Please check the following:

1. Is this app supposed to be run as the app user?
2. Is this app being run on the correct Ruby interpreter? Below you will see which Ruby interpreter Phusion Passenger attempted to use.

-------- The exception is as follows: -------

Could not find rake-11.1.2 in any of the sources (Bundler::GemNotFound)
