Terraform: associate_public_ip_address always true!

[P13612]

Hi,

in

terraform/builtin/providers/aws/resource_aws_instance.go

the parameter

associate_public_ip_address

is always associating a public ip-address even when set to false.

associate_public_ip_address = false

I have no idea of Golang even though its looking like a fascination programming language.
Can somebody correct this behavior?

Thanks

Hi @P13612

Please can you supply a sample of the config that you are using and we can see if this bug can be reproduced?

Thanks

Hi Paul,

so quick? Thank you. Here is your example:

resource "aws_instance" "app" {
ami = "${var.anylinuxami}"
instance_type = "t2.micro"
associate_public_ip_address = false
subnet_id = "${aws_subnet.private_1.id}"
private_ip = "10.130.0.7"
security_groups = ["default"]
key_name = "${var.key_name}"
tags {
Name = "APP"
}
}

It's fairly straightforward. It's simply an instance inside a private subnet.

Thank you for your quick response again

Hi @P13612

I believe this is the issue. You are trying to assign a public_ip to an instance in a private_subnet. I would take a punt and suggest that the private_subnet doesn't actually create public_ip address

Hi Paul,

but I'm doing this:

associate_public_ip_address = false
subnet_id = "${aws_subnet.private_1.id}"
private_ip = "10.130.0.7"

I'm associating a private IP and I want no public IP therefore I set

associate_public_ip_address = false

I even didn't use this parameter at all and still I get a public IP

Hi @P13612

Apologies - ok so can you show me the configuration that creates a subnet?

Paul

[P13612]

Sure,
resource "aws_subnet" "private_1" {
vpc_id = "${aws_vpc.vpc.id}"
cidr_block = "10.130.0.0/27"
availability_zone = "us-west-1a"
map_public_ip_on_launch = true
tags {
Name = "myprivatesubnet"
}
}

oops! Is this my problem?

map_public_ip_on_launch = true

That's the issue :)

Hi Paul,

I dropped the line and all is fine.

Thank you

this happened to me and some other people on the interwebtz as well it seems. maybe worth noting in the docs?
