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:

[webserver]192.168.204.70192.168.204.71[dbserver]192.168.204.72192.168.204.73192.168.204.75[proxy]192.168.204.76192.168.204.77192.168.204.78[test]192.168.204.79192.168.204.80[haproxy]192.168.205.82192.168.204.83 

用python将ansible配置转为json格式,python代码如下:

import ConfigParserimport jsondict_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:

#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:

<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:
