This module polls a series of fairly well known but occasionally unreliable 'what is my ip' services. It then produces the most common response that is a valid ipv4 or ipv6 address (both outputs are separately provided).

Especially useful if you have connection hashing - the distinct matches outputs will provide a list of your current public source addresses.

The goal of this module is to provide a valid-enough answer even when the internet does what the internet does, which is to be flaky and broken somewhere, sometime.

Neither thecurl2 norhttp providers are perfectly suited to the internet since they will fail a run if the url doesn't respond and/or the url doesn't resolve. Thecurl2 provider is slightly more reliable than thehttp provider. This failure mode makes sense if it's a critical part of your terraform..

Both ofcurl2 andhttp providers are provided as a matter of them being possibly better in the future if/when they have someignore_failure options.

Since we're aggregating results to achieve a 'most common' response it frankly shouldn't matter if one of the endpoints in the list fails to respond - we will have gathered enough data to make a good response. Let the build roll on!

As such we implement anexternal_curl using theexternal provider and a shim scriptexternal_curl.sh, which will survive a truly non-resolving non-responsive endpoint by faking the response data, which will be filtered out later by ouripv4_matches andipv6_matches filters.

The failed builds because the myip service I had chosen wasn't working or there was a routing error in the pipeline. I owe it all to you!
