Create Multiple AWS Elasticache Redis Clusters With Terrafrom

Prerequisites

• Download terrafrom from: https://www.terraform.io/downloads.html
• Follow the instructions and add terraform executable to PATH: https://learn.hashicorp.com/terraform/getting-started/install.html
• Edit your ~/.aws/credentials and add a terraform section:

  [terraform]
  aws_access_key_id = __id__
  aws_secret_access_key = __key__
  

Mandatory variables in terrafrom.tfvars
