Change into our working directory:

$ mkdir -p myworkdir/src 
$ cd myworkdir

Create a virtual env:

provider.tf:

$ cat provider.tf
provider "aws" {
  version = "~> 2.0"
  region  = "eu-west-1"
  profile = "dev"
  shared_credentials_file = "~/.aws/credentials"
}

In BASH:

# usage: ./pushover-notify home-pc "homepc notification"
#!/bin/bash
APP_TOKEN='x'
USER_TOKEN='x'
TITLE="$1"
MESSAGE="$2"
curl 'https://api.pushover.net/1/messages.json' -X POST -d "token=$APP_TOKEN&amp;user=$USER_TOKEN&amp;message=\"$MESSAGE\"&amp;title=$TITLE"

Return random string from array:

#!/usr/bin/env bash
subnets[0]="subnet1"
subnets[1]="subnet2"
subnets[2]="subnet3"

size=${#subnets[@]}
index=$(($RANDOM % $size))
