各位用户为了找寻关于python将ansible配置转为json格式实例代码的资料费劲了很多周折。这里教程网为您整理了关于python将ansible配置转为json格式实例代码的相关资料,仅供查阅,以下为您介绍关于python将ansible配置转为json格式实例代码的详细内容

python将ansible配置转为json格式实例代码

ansible的配置文件举例如下,这种配置文件不利于在前端的展现,因此,我们用一段简单的代码将ansible的配置文件转为json格式的:

? 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 [webserver] 192.168.204.70 192.168.204.71   [dbserver] 192.168.204.72 192.168.204.73 192.168.204.75   [proxy] 192.168.204.76 192.168.204.77 192.168.204.78   [test] 192.168.204.79 192.168.204.80   [haproxy] 192.168.205.82 192.168.204.83

用python将ansible配置转为json格式,python代码如下:

? 1 2 3 4 5 6 7 8 9 import ConfigParser import json dict_result = {} cf = ConfigParser.ConfigParser(allow_no_value=True) cf.read('/etc/ansible/hosts.test') secs = cf.sections() for sec in secs:  dict_result[sec] = cf.options(sec) print json.dumps(dict_result)

 转换结果如下(python版本使用2.7版本的):

/usr/local/python/bin/python /tmp/test.py {"test": ["192.168.204.79", "192.168.204.80"], "haproxy": ["192.168.205.82", "192.168.204.83"], "webserver": ["192.168.204.70", "192.168.204.71"], "proxy": ["192.168.204.76", "192.168.204.77", "192.168.204.78"], "dbserver": ["192.168.204.72", "192.168.204.73", "192.168.204.75"]}

 转换成json文件就方便在前端进行展示了,使用Flask提供json格式的接口如下:

? 1 2 3 4 5 6 7 8 9 10 11 #获取ansible分组 @app.route('/web_test/ansible') def web_test_ansible():   dict_result = {}   cf = ConfigParser.ConfigParser(allow_no_value=True)   cf.read('/etc/ansible/hosts.test')   secs = cf.sections()   for sec in secs:     dict_result[sec] = cf.options(sec)   return json.dumps(dict_result)

然后前端代码(使用bootstrap treeview)如下:

? 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 <script src="/static/js/bootstrap-treeview.js"></script>   <script type="text/javascript">     $(document).ready(function () {         $('#btn-get-hostgroup').click(function () {         getAllCheck = $('#hostgrouptree').treeview('getChecked');         for (var i = 0; i < getAllCheck.length; i++) {           console.log(getAllCheck[i].text);         }       });           $.ajax({         url: '/web_test/ansible',         type: 'GET',         success: function (data) {           result = JSON.parse(data);           nodes = [];           for (var hostgroup in result) {             var nodeshostgroup = [];             hosts = result[hostgroup];             for (var i = 0; i < hosts.length; i++) {               nodeshostgroup.push({text: hosts[i], selectable:false});             }             nodes.push({text: hostgroup, nodes: nodeshostgroup, selectable:false});           }           $('#hostgrouptree').treeview({data: [{text: 'all', nodes: nodes, selectable:false}], showCheckbox: true, showBorder:false});         }       });     });   </script> {% endblock %} {% block page_content %}     <div class="col-md-4" id="hostgrouptree">     </div>     <div class="col-md-6">     <button id="btn-get-hostgroup" type="button" class="btn btn-default">获取选中的组</button>   </div>

ansible的配置文件在前端的展示如下,获取ansible选中的组,利用ansible命令就可以实现一些简单的自动化操作了:
