Associate EIP with ENI - AWS

Hi All

Chef-Provisioning - I’ve created an elastic network interface, and can attach to an instance. But I then want to associate an Elastic IP to the interface. I can only see an option to associate EIP to the machine itself, not the ENI…am I missing something(probably)?

require 'chef/provisioning/aws_driver'
with_driver 'aws'

aws_network_interface "eni-test" do
  machine 'i-xxxxxxx'
  subnet 'subnet-xxxxxxx'
  security_groups ['sg-xxxxxxxx','sg-xxxxxxx']
  description 'test ENI'
  device_index 1

aws_eip_address '' do
  machine ' blah' << -This is where i'd expect to see an option to associate to ENI
