Answer 1

Bundler 2 requires at least Ruby 2.3.0 and RubyGems 2.5.0. You might get the following error when you try to install bundler for Ruby < 2.3:

COPY

  ERROR:  Error installing bundler:
  bundler requires Ruby version >= 2.3.0.

To fix this error upgrade your project's ruby version or install the last supported version of Bundler for Ruby < 2.3:

COPY gem install bundler -v '~>1'
