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 9import
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:
