使用JSON的Chef-solo run_list錯誤

Question

首先嘗試用廚師獨奏旋轉一個流浪漢。 現在遇到由於我的node.json文件導致的錯誤，其他人曾嘗試在SO上解決過幾次 。 VM是Ubuntu 12.04，工作站和節點都運行10.16.2。

這是node.json：

{
  "name": "apptron",
  "description": "slightly complicated config",
  "chef_type": "role",
  "json_class": "Chef::Role",
  "default_attributes": {},
  "env_run_lists": {
     "_default": [],
     "production": [],
     "staging": [],
     "test": [],
     "monitoring": [],
     "queuing": []
  },
 "run_list": ["recipe[base]", "recipe[user]"],
 "override_attributes": {}
}

在節點上棧跟蹤：

Answer 1

事實證明問題在於node.json密鑰json_class: "Chef::Role"由於某種原因，當我應用它時，我得到了奇怪的錯誤。 當我不這樣做時，一切都按照Vagrant的預期運行。

Answer 2

您將角色json數據放入節點json文件中，這是導致此問題的原因。

這一點：

"chef_type": "role",
"json_class": "Chef::Role",

屬於json角色。

在我的情況下，我在角色json中有節點json數據，在節點json中有角色json數據... herp derp :)
