# The goal: create a list of maps of subnet mappings so we don't have to statically hard-code them in aws_lb
# https://www.terraform.io/docs/providers/aws/r/lb.html#subnet_mapping
locals {
  # These represent dynamic data we fetch from somewhere, such as subnet IDs and EIPs from a VPC module
  subnet_ids = ["subnet-1", "subnet-2", "subnet-3"]
  eips       = ["eip-1", "eip-2", "eip-3"]
}

# Here's the hack! The null_resource has a map called triggers that we can set to arbitrary values. 
# We can also use count to create a list of null_resources. By accessing the triggers map inside of

Exporting your 2FA tokens from Authy to transfer them into another 2FA application

IMPORTANT - Update regarding deprecation of Authy desktop apps

Past August 2024, Authy stopped supported the desktop version of their apps:
See Authy is shutting down its desktop app | The 2FA app Authy will only be available on Android and iOS starting in August for details.

And indeed, after a while, Authy changed something in their backend which now prevents the old desktop app from logging in. If you are already logged in, then you are in luck, and you can follow the instructions below to export your tokens.

If you are not logged in anymore, but can find a backup of the necessary files, then restore those files, and re-install Authy 2.2.3 following the instructions below, and it should work as expected.

MicroService Proxy Gateway Solutions

Kong, Traefik, Caddy, Linkerd, Fabio, Vulcand, and Netflix Zuul seem to be the most common in microservice proxy/gateway solutions. Kubernetes Ingress is often a simple Ngnix, which is difficult to separate the popularity from other things.

Originally, I had included some other solution
