如何從劇本中獲得更多可用的錯誤信息？

Question

ansible-playbook給我的錯誤看起來像這樣：

fatal: [test.example.com]: FAILED! => {"changed": false, "cmd": "./manage.py migrate --noinput 
--pythonpath=/srv/virtualenv/myapp/bin/python3", "failed": true, "msg": "\n:stderr: Traceback (most recent call last):\n File \"./manage.py\", line 10, in <module>\n execute_from_command_line(sys.argv)\n File \"/srv/virtualenv/myapp/lib/python3.5/site-packages/django/core/management/__init__.py\", line 354, in execute_from_command_line\n utility.execute()\n File \"/srv/virtualenv/myapp/lib/python3.5/site-packages/django/core/management/__init__.py\", line 303, in execute\n settings.INSTALLED_APPS\n File \"/srv/virtualenv/myapp/lib/python3.5/site-packages/django/conf/__init__.py\", line 48, in __getattr__\n self._setup(name)\n File \"/srv/virtualenv/myapp/lib/python3.5/site-packages/django/conf/__init__.py\", line 44, in _setup\n self._wrapped = Settings(settings_module)\n File \"/srv/virtualenv/myapp/lib/python3.5/site-packages/django/conf/__init__.py\", line 92, in __init__\n mod = importlib.import_module(self.SETTINGS_MODULE)\n File \"/srv/virtualenv/myapp/lib/python3.5/importlib/__init__.py\", line 126, in import_module\n return _bootstrap._gcd_import(name[level:], package, level)\n File \"<frozen importlib._bootstrap>\", line 986, in _gcd_import\n File \"<frozen importlib._bootstrap>\", line 969, in

當然，我可以複製此並粘貼到ipython得到的東西更有用的觀點，即

但我像ansible爲我做。我怎樣才能做到這一點？

這是相關的，但並不像解決我的問題：Ansible playbook shell output

Answer 1

Ansible允許您使用callback plugins來控制它的輸出，並提供了一些可選的回調out of the box。

配置它們簡單地設置callback_plugs option在ansible.cfg：

callback_plugins = ~/.ansible/plugins/callback:/usr/share/ansible/plugins/callback 

要獲得Ansible打印換行，而不是使他們爲\n是你可以開發自己的回調或簡單地使用所制定的human_log回調插件Cliffano Subagio。

對於Ansible 2的兼容性（插件系統從Ansible 1.x版本升級改寫而來），等效文件爲n0ts。

Answer 2

增加詳細程度。在ansible-playbook命令的末尾添加-vvvv。它會將詳細程度設置爲4，並且大多數日誌都足夠好。
