如何使用 terraform 将 EIP 附加到现有的 ENI（在 terraform 之外创建）

Question

Hello I'm trying to attach EIP to ENI using terraform. Both EIP and ENI are created outside of terraform.

Following are the manual steps:

• Need to allocate a IP address in su.net for the ENI
• Associate EIP to the ENI on the previously allocated IP address.

Is there anyway to automate this using terraform?

Found the solution. Looks like terraform natively doesn't support requesting private ip to ENI. So used data external resource to create a secondary ip to existing ENI and used " aws_eip_association " resource to associate EIP to ENI on Private IP created using data external resource.
