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:

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:
