How to install ruby and bundler via Chef?

Question

I'm new to Chef and I'm trying, for hours now, figure out how to install ruby and install the gem bundler, I'm new to ruby too.

I would like to clone my repository and execute like this:

$ bundle install
$ bundle exec rackup

Simple via Shell scripts, but it seems, for now, very difficult with Chef. Although, I created this recipe:

metadata.rb

depends 'apt'
depends 'git'
# depends 'rbenv' -> # very old version
depends 'ruby_rbenv' # -> new version
depends 'application'
depends 'application_ruby'
depends 'build-essential'

metadata.rb

include_recipe 'git'
include_recipe 'ruby_rbenv::system'
include_recipe 'build-essential'

rbenv_global 'system'

group 'sinatra_app'

user 'sinatra_app' do
  group 'sinatra_app'
  system true
  shell '/bin/bash'
end

# DON'T WORK    
# rbenv_gem "bundler" do
  # action :install
# end

# DON'T WORK
# rbenv_gem "bundler" do
  # ruby_version "2.4.0"
# end

directory '/srv/sinatra-app' do
  owner 'sinatra_app'
  group 'sinatra_app'
  mode '0755'
  recursive true
end

application '/srv/sinatra-app' do
  # Application resource properties.
  owner 'sinatra_app'
  group 'sinatra_app'

  # Subresources, like normal recipe code.
  package 'ruby'
  git "/srv/sinatra-app" do
    repository "git://github.com/tnh/sinatra-app.git"
    reference "master"
    action :sync
  end

  # DON'T WORK
  bundle_install do
    deployment true
  end

end

But I'm not sure if ruby is being installed properly. And also the bundle_install it seems not be working..

And this is my error output:

Any help would be very much appreciated!

You're already using application_ruby which depends on poise-ruby so use that. Check out the docs at https://github.com/poise/poise-ruby but short version just add ruby_runtime 'myapp' to the application block.

You can also check out application_examples for a more detailed example. That's for rails but you can probably figure out how to adapt it for sinatra.
