Description

It seems you can't use ipv6_addresses or ipv6_address_count with aws_network_interface. Requesting addition of support here. Issue is: if you have an EC2 instance with multiple ENIs, you can't manage ipv6 with it. You can only seem to mange ipv6 with and ENI when it is the primary ENI via aws_instance using arguments ipv6_addresses or ipv6_address_count. I believe we should have the same two arguments available for aws_network_interface.

I believe vendor\github.com\aws\aws-sdk-go\service\ec2\api.go has the necessary methods to call from aws\resource_aws_network_interface.go.

This is regarding provider version 2.51.0.

New or Affected Resource(s)

• aws_network_interface (affected)

Potential Terraform Configuration

Example - I'd like to be able to something like this and assign both ipv6 and private ipv4 addresses to an ENI. Today, ipv6_addresses is not a valid argument for this resource (nor is ipv6_address_count).

resource "aws_network_interface" "fw1_eni" {
  description       = "interface 1 for firewall 1"
  subnet_id         = var.subnet_ids[0]
  ipv6_addresses = [var.ips_v6[0]]
  private_ips       = [var.ips_v4[0]]
  security_groups   = [aws_security_group.fw_sg_1.id]
  source_dest_check = false
}
