起因
历史遗留问题导致CMDB (配置管理数据库) 数据错误,内网机器200多台,逐一核对显然太不现实; (浪费人力);
2.解决问题思路 ;
读取docker 平台ip接口，和cmdb 平台接口生成文件，进行文件对比，）注意:文件对比前需要排序下 linux 平台推荐 （sort命令）;
3.读取接口代码;
# -*- coding: utf-8 -*-
import requests
import json
url = " ####cmdb 接口地址 ###
docker_data = requests.get(url)
data=docker_data.text
json_dict = json.loads(data)
for i in json_dict.get("data"):
cmdb_private_ip = i.get("private_ip")
if cmdb_private_ip:
try:
f = open('/tmp/private_ip', 'ab+')
f.write(cmdb_private_ip)
finally:
if f:
f.close()
4.文件对比脚本;
#!/usr/bin/python
# -*- coding: utf-8 -*-
import sys
import difflib
try:
docker_ipaddress= sys.argv[1]
cmdb_ipaddress = sys.argv[2]
except IndexError,e:
print("文件不存在,%s") % str(e)
sys.exit()
def readline(filename):
try:
f = open(filename,"rb")
lines = f.read().splitlines()
f.close()
return lines
except ImportError as error:
print("文件为空%s") % str(error)
sys.exit()
docker_lines = readline(docker_ipaddress)
cmdb_lines = readline(cmdb_ipaddress)
d = difflib.HtmlDiff()
data = d.make_file(docker_lines,cmdb_lines)
with open("/data/upload/docker_cmdb_file_ip") as file:
file.write(data)
脚本执行命令;
[root@devops]# python chechk_pas.py docker_new.txt cmdb_docker_new.txt
5.文件结果展示;
