Description: >-
  AWS CloudFormation Sample Template Sample template EIP_With_Association: This
  template shows how to associate an Elastic IP address with an Amazon EC2
  instance - you can use this same technique to associate an EC2 instance with
  an Elastic IP Address that is not created inside the template by replacing the
  EIP reference in the AWS::EC2::EIPAssoication resource type with the IP
  address of the external EIP. **WARNING** This template creates an Amazon EC2
  instance and an Elastic IP Address. You will be billed for the AWS resources
  used if you create a stack from this template.
