Question

我试图从厨师食谱中读取加密数据包，但我遇到了一些问题。

我以这种方式创造了秘密

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

如您所见，我将加密版本放在一个单独的数据包中以进行测试。得到的数据库就像这样：

{
  "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"
  }
}

然后我使用这个片段处理我的食谱：

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

当我尝试使用此配方运行厨房时，我收到此错误：

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

Stacktrace本身并没有真正起作用：

我知道秘密是正确的（如果我打印出来它包含我的秘密文件的完全相同的值）并且数据包是正确的（如果我尝试使用search( :test, "id:poweruser").first我获取加密值）

我可以尝试获取有关错误的更多信息并解决它？

谢谢，米歇尔。

Answer 1

为什么要读取ruby_block中的数据包？您必须从主要上下文中读取它，如https://docs.chef.io/data_bags.html#load-with-recipe-dsl
404错误说，服务器上的数据包不存在。（可能由＃1引起）
如果使用默认的机密文件位置，则读取加密数据包是完全透明的。您可以坚持使用data_bag或data_bag_item方法。

如果未指定'secret'，chef-client将在client.rb文件中的encrypted_data_bag_secret设置指定的路径中查找秘密。

请参阅https://docs.chef.io/data_bags.html

Answer 2

您可以从厨师食谱中读取数据包，如下所示：Chef::EncryptedDataBagItem.load('data_bag_name','data_bag_item_name')
