如何閱讀廚師食譜中的加密數據包？

我正嘗試從廚師食譜中讀取加密的數據包，但遇到一些問題。如何閱讀廚師食譜中的加密數據包？

我這樣

openssl rand -base64 512 > test/integration/default/encrypted_data_bag_secret 
knife data bag from file test ../data_bags/system_user/poweruser.json --secret-file test/integration/default/encrypted_data_bag_secret 
knife data bag show test ccbuildub -Fj > ../data_bags/test/poweruser.json

創建的祕密正如你可以看到我把加密版本處於分離的數據包進行測試的目的。得到的databag是這樣的：

{ 
    "id": "poweruser", 
    "username": { 
    "encrypted_data": "48y/E3yzDWXvbD/J72tZuvS5jpDwnA8RvI6bJhnQHFU=\n", 
    "iv": "O+WKxIAXH1pDTBqGluGCsw==\n", 
    "version": 1, 
    "cipher": "aes-256-cbc" 
    }, 
    "password": { 
    "encrypted_data": "JHHSoaIm9b8FxCOfTfrQRb0YmoabCcTcXXx/0nwU/j3gQCXd1kEHbxpEHZMB\n92A6\n", 
    "iv": "Cn5ct0xt4PKHptz+WmbFmw==\n", 
    "version": 1, 
    "cipher": "aes-256-cbc" 
    }, 
    "domain": { 
    "encrypted_data": "bhFJ9FRTlIuo1s7JZEs79SkNSxDw+9OJtBxkpMdoxOorYqxBbo6lZA3+BP3u\njWk1\n", 
    "iv": "BvOD0l4ohTwOJka74rlFVw==\n", 
    "version": 1, 
    "cipher": "aes-256-cbc" 
    } 
}

然後，我用我的食譜在這個片段的工作：

ruby_block "do something" do 
    block do 
     secret = Chef::EncryptedDataBagItem.load_secret(Chef::Config[:encrypted_data_bag_secret]) 
     decryptedObject = Chef::EncryptedDataBagItem.load("test","poweruser") 
     print "DECRYPT : " + decryptedObject.to_s 
     [...] 
    end 
end

當我嘗試運行使用這個配方的廚房我得到這個錯誤：

[2016-11-24T11:32:23+00:00] ERROR: ruby_block[do something] (SPMLinuxBuilder::mountTiny line 11) had an error: Net::HTTPServerException: 404 "Not Found"

堆棧跟蹤本身並沒有真正幫助：

我知道的祕密是正確的（如果我把它打印出來它包含了我的祕密文件完全相同的值），該數據包是正確的（如果我嘗試使用search(:test, "id:poweruser").first我獲得的加密值）

什麼我可以嘗試獲得有關錯誤的更多信息並解決它嗎？

謝謝，米歇爾。

你爲什麼要讀ruby_block裏面的數據包嗎？您必須從主環境中讀取它，如https://docs.chef.io/data_bags.html#load-with-recipe-dsl中所述
404錯誤說，數據包在服務器上不存在。（可能是由＃1引起的）
如果使用默認祕密文件位置，讀取加密數據包是完全透明的。您可以堅持使用data_bag或data_bag_item方法。

If 'secret' is not specified, the chef-client will look for a secret at the path specified by the encrypted_data_bag_secret setting in the client.rb file.

看到https://docs.chef.io/data_bags.html

謝謝，這使我在正確的方式，我可能下面一個錯誤的榜樣。唯一的是我仍然需要使用這個命令來獲得祕密'祕密= Chef :: EncryptedDataBagItem.load_secret（Chef :: Config [：encrypted_data_bag_secret]）''作爲IO.read方法在doc給我一個錯誤檢索文件（如果我指定了路徑）。 – Mikyjpeg

無論如何，我應該繼續在一個紅寶石塊內使用它，否則編譯失敗，如果祕密文件不存在（我複製它在以前的塊）。無論如何，ruby塊正在使用數據包中的值進行其他工作，所以它不是太糟糕。 – Mikyjpeg

你可以閱讀從廚師的食譜如下數據BAGE：Chef::EncryptedDataBagItem.load('data_bag_name','data_bag_item_name')
