Problem this snippet solves:

Python script which pulls O365 URL's/IP's from microsoft published XML formatted list, parses into python dictionaries formatted for F5 data group, and uses F5 Python SDK to create or update data groups on BIG-IP for each MS product. The script will check if the data group already exists, and if so update based on changes. Once the data groups are installed they can used/referenced by any F5 feature/configuration that can reference a data group.

How to use this snippet:

Python version: 3.6

Python Modules Required: * f5-sdk * requests * f5-icontrol-rest * xmltodict

Update script variables for your environment: BIGIP_ADDRESS = ' ' BIGIP_USER = ' ' BIGIP_PASS = ' '

to execute: python3 o365_dg_builder.py

Code :

import requests
import xmltodict
from collections import OrderedDict
from f5.bigip import ManagementRoot
from icontrol.exceptions import iControlUnexpectedHTTPError

import argparse

MS_URL = 'https://support.content.office.net/en-us/static/O365IPAddresses.xml'
BIGIP_ADDRESS = '192.168.15.165'
BIGIP_USER = 'admin'
BIGIP_PASS = 'admin'

def load_bigip(f5_host, f5_user, f5_pass):
    bigip = ManagementRoot(f5_host, f5_user, f5_pass)

    return bigip

Hi,

 

Right now Microsoft change to use JSON format instead via https://endpoints.office.com/endpoints/worldwide?clientrequestid=b10c5ed1-bad1-445f-b386-b919946339a...

 

The parser in python script might not working with JSON format right?
