用python將ansible配置轉爲json格式

ansible的配置文件舉例以下，這種配置文件不利於在前端的展示，所以，咱們用一段簡單的代碼將ansible的配置文件轉爲json格式的：

[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將ansible配置轉爲json格式，python代碼以下：

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)

 

轉換結果以下(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"]}

 

轉換成json文件就方便在前端進行展現了，使用Flask提供json格式的接口以下：

#獲取ansible分組
@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)

 

而後前端代碼(使用bootstrap treeview)以下：

<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">獲取選中的組</button>
    </div>

 

ansible的配置文件在前端的展現以下，獲取ansible選中的組，利用ansible命令就能夠實現一些簡單的自動化操做了：
