Chef创建具有公共密钥访问权限的用户帐户

Question

我正在尝试创建一个食谱，该食谱会在食谱的文件目录中查找，并根据目录中的每个公钥创建一个用户。

cookbooks/users/files/default目录包含：

id_rsa_123456789.pub id_rsa_234567890.pub

基于这两个文件，我想创建两个名为123456789和234567890的用户帐户，并将它们的公钥分别放在/home/$USER/.ssh/中。

cookbooks/users/attributes/default.rb包含：

default['users']['pub_keys'] = {}

Dir.foreach('../files/default/') do |pub_key|
  if pub_key =~ /\d.pub/
    default['users']['pub_keys'][pub_key] = pub_key.match(/[0-9]{9}/)
  end
end

此代码应创建以下内容：

default['users']['pub_keys'] = {'id_rsa_123456789.pub' => '123456789', 'id_rsa_234567890.pub' => '234567890' }

cookbooks/users/recipes/default.rb包含：

node['users']['pub_keys'].each do |pub_key, sso|
  user sso do
    action :create
    group 'sudoers'
    home "/home/#{sso}"
  end
  directory "/home/#{sso}/.ssh" do
    action :create
  end
  cookbook_file "/home/#{sso}/.ssh/#{pub_key}" do
    source pub_key
    owner sso
    group sso
    mode '0400'
    action :create
  end
end

我认为我的食谱无法读取我的哈希变量，但不确定为什么或如何解决。
