dpneumo / !Geocode an Address
Last active January 13, 2021 02:45
Geocode an address hash with Google geocode api
I needed a tool to add latitude and longitude to seeds.rb in a Rails application.
geocoder.rb uses the Google geocode api. An apikey is required. For limited use it is free. The apikey should be protected from prying eyes. (encryption, .gitignore, ...)
Geocoder#geocode takes an address string in canonical form ( "#{number} #{street} #{city} #{state}" ) as input. It returns latitude and longitude as a hash: { lat: 30.0000, lng: -90.000 }
seed_geocoder.rb extracts the address string from seeds.rb, requests the geocode hash from the Geocoder obj and writes the newseeds.rb file.
The newseeds file does need some minor additional work to make it a functional seeds.rb.

Modify cloud-init phone_home module to return a created server's public key for insertion into known_hosts. Works with cloud-iniit version 0.7.9 and later.
# Diff of the original cc_phone_home and the slightly modified version that supports
# including the server pub_keys in the phone_home payload
# Original: https://github.com/number5/cloud-init/blob/master/cloudinit/config/cc_phone_home.py
# A couple of typos in comment lines in the original were elided to make the diff a bit clearer.
# The Centos7 distros I am using do not provide pub_key_dsa.
# I am talking to a Rails app with phone_home.
# A dummy X-CSRF-Token: 1234567890 in the headers simplifies the code on the Rails side.
# I authenticate the phone_home payload by including a token provided in the
