Terraform: Can't get AWS instance id to associate EIP with.

[fog1985]

Hi guys,

I parsed Google and what I found is to get AWS instance_id it is enough to use the construction as follow:
"${aws_instance.test_terraform.id}"

But whenever I try to use it this way I get an error as follow:

• aws_instance.test_terraform: aws_instance.test_terraform: self reference not allowed: "aws_instance.test_terraform.id"

Doesn't matter if I try to save it into a variable or use from resource "aws_eip_association".
Always get this error.

But this way of doing that stuff even described here:
https://www.terraform.io/docs/providers/aws/r/eip_association.html

Can anyone help me please with this and whet I am doing wrong?

Regards,
Taras.

Hi @stack72
I have just reviewed my config and found very simple but not very obvious error. :)
I tried to associate EIP inside of instance creation block.
Just moved it outside and everything works as expected.

Sorry to disturb you.

Regards,
Taras.
