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]
192.168.204.70
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:
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:
#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:
