Updates Cloudflare with current IP

So I got sick of all those free dynamic dns services and fortunately some nice person on Reddit came up with this idea: https://www.reddit.com/r/raspberry_pi/comments/9nimtz/use_cloudflare_as_dynamic_dns_with_raspberry_pi/ If you are a Redditor please go give u/TheFirsh some tasty tasty karma.

Cloudflare will host your DNS for free, on top of a whole heap of other benefits, and they have a really good API for updating DNS records. The idea is that you run this script like you would a dynamic DNS client - it's python so entirely cross platform and uses minimal and very common libraries.

config.json

You will need to create a config.json file in the same folder as pyflare.py - this file must be json formatted and contain the following 4 elements.

{
  # Log level for the program; it will log anything at this level or higher
  # "DEBUG", "INFO", "WARNING", "ERROR", "CRITICAL"
  # You can overwrite this with the PYFLARE_LOG_LEVEL env variable
  "log_level": "",
  # The email address on your Cloudflare account
  "email": "",
  # The Global API key on your account
  "key": "",
  # The zone for which you'll be updating a record (ie example.com)
  "zone": "",
  # The record for which you'll be updating (ie home.example.com)
  # This record should already exist in Cloudflare
  "record": ""
}

You can also change the log level (useful for debugging purposes mainly) one time, by setting the PYFLARE_LOG_LEVEL environment variable:

$ export PYFLARE_LOG_LEVEL
