AWS::EC2::EIPAssociation

EC2 EIPAssociation

Associates an Elastic IP address with an instance or a network interface. Before you can use an Elastic IP address, you must allocate it to your account. For more information about working with Elastic IP addresses, see [Elastic IP address concepts and rules](https://docs.aws.amazon.com/vpc/latest/userguide/vpc-eips.html#vpc-eip-overview). You must specify AllocationId and either InstanceId, NetworkInterfaceId, or PrivateIpAddress.
