Ansible API 2.0的測試

default roo ges ria toolbar bsp ict eve uem 因項目需要使用到ansible api,根據修改官方文檔提供的使用範例,經過多次測試,現將能用的代碼分享給大家,大家只需根據自己的實際環境修改該代碼即可。
官方文檔:http://docs.ansible.com/ansible/latest/dev_guide/developing_api.html#python-api-2-0
#coding:utf-8 import json from collections import namedtuple from ansible.parsing.dataloader import DataLoader from ansible.vars.manager import VariableManager from ansible.inventory.manager import InventoryManager from ansible.playbook.play import Play from ansible.executor.task_queue_manager import TaskQueueManager from ansible.plugins.callback import CallbackBase class ResultCallback(CallbackBase): def v2_runner_on_ok(self, result, **kwargs): host = result._host print(json.dumps({host.name: result._result}, indent=4)) # 初始化需要的對象 Options = namedtuple('Options', ['connection', 'module_path', 'forks', 'become', 'become_method', 'become_user', 'check', 'diff']) # module_path參數指定本地ansible模塊包的路徑 loader = DataLoader() options = Options(connection='smart', module_path='/usr/lib/python2.7/dist-packages/ansible/modules', forks=5, become=None, become_method=None, become_user="root", check=False, diff=False) passwords = dict(vault_pass='secret') # 實例化ResultCallback來處理結果 results_callback = ResultCallback() # 創建庫存(inventory)並傳遞給VariableManager inventory = InventoryManager(loader=loader, sources=['../conf/hosts']) #../conf/hosts是定義hosts variable_manager = VariableManager(loader=loader, inventory=inventory) # 創建任務 play_source = dict( name = "Ansible Play", hosts = "cephnode", gather_facts = 'no', tasks = [ dict(action=dict(module='shell', args='touch /tmp/7.txt'), register='shell_out'), #定義一條任務,如有多條任務也應按照這樣的方式定義 ] ) play = Play().load(play_source, variable_manager=variable_manager, loader=loader) # 開始執行 tqm = None try: tqm = TaskQueueManager( inventory=inventory, variable_manager=variable_manager, loader=loader, options=options, passwords=passwords, stdout_callback=results_callback, # 使用自定義回調代替“default”回調插件(如不需要stdout_callback參數則按照默認的方式輸出) ) result = tqm.run(play) finally: if tqm is not None: tqm.cleanup()
我的../conf/hosts文件內容如下:
[cephnode]
192.168.89.136
註意:
如沒有明確指定inventory(如下的參數),那麽會默認從/etc/ansible/hosts中讀取hosts
sources=['../conf/hosts']
補充一下,剛說了定義多條任務的方式,舉個例子:
tasks = [ dict(action=dict(module='shell', args='mkdir /tmp/toby'), register='shell_out'), #首先創建目錄 dict(action=dict(module='copy', args='src=/tmp/abc123.txt dest=/tmp/toby'), register='shell_out') #然後將本地的abc123.txt通過copy模塊下發到目標主機的/tmp/toby/目錄下 ]
