如何通过 Chef 安装 ruby​​ 和 bundler？

Question

我是 Chef 的新手，我正在尝试几个小时，弄清楚如何安装 ruby​​ 并安装 gem bundler，我也是 ruby 的新手。

我想克隆我的存储库并像这样执行：

$ bundle install
$ bundle exec rackup

通过 Shell 脚本很简单，但目前看来，使用 Chef 非常困难。 虽然，我创建了这个食谱：

元数据.rb

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

元数据.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

但我不确定是否正确安装了 ruby​​。还有bundle_install 似乎不起作用..

这是我的错误输出：

您已经在使用application_ruby，这取决于poise-ruby，所以使用它。查看https://github.com/poise/poise-ruby 的文档，但简短版本只需将ruby_runtime 'myapp' 添加到应用程序块。

您还可以查看application_examples 以获取更详细的示例。这是针对 Rails 的，但您可能会弄清楚如何将其适应 sinatra。
