set static IPs / how to use private_ip_addresses

[daodennis]

Hi,

I am trying to setup two boxes using one of two IP addresses depending on which subnet / availability zone it is placed in but passing in a list of IP addresses yields. I have considered setting up a /28, but I don't necessarily need 14 or so addresses for this use-case, however would love an ASG in case the instance goes down.

I have also tried to pass in an aws_network_interfaces into the module, and that actually has either no effect or an error like local. security_group_ids is tuple with 4 elements

Error: updating Auto Scaling Group (fix-20231103045202846800000001): InvalidQueryParameter: Incompatible launch template: Auto Scaling does not support Private IP addresses.
│   status code: 400, request id: b019077e-a28b-40d8-8afc-7390c607633e

│   on .terraform/modules/role/main.tf line 345, in resource "aws_autoscaling_group" "this":
│  345: resource "aws_autoscaling_group" "this" {
│

The above is from setting these:

  network_interfaces = [
    {
      delete_on_termination = false
      description           = "eth0"
      device_index          = 0
      security_groups       = local.security_group_ids
      ipv4_addresses          = ["10.2.10.10", "10.2.16.16"]
    }
  ]

I have also like I said above tried to create two aws_network_interfaces and passed them in as two interfaces in a list or aws_network_interfaces.name[*] <-- this has no effect, the prior yields the error about security groups not being the correct type from above.

Слава Україні!

This cannot be implemented using the autoscaling groups feature or this module. Please ask generic questions about this or Terraform at https://discuss.hashicorp.com and check the official AWS documentation for available features.
