Error tracking route_table_association on deletion

[Vlatombe]

This happens from time to time on terraform destroy, I believe it to be caused by a race condition between route_table and route_table_association.

This looks very much like #2295, so I will propose a similar fix.

Version: terraform 0.6.3 linux x64

Initial terraform configuration

resource "aws_vpc" "tiger" {
    cidr_block = "10.16.0.0/16"

    enable_dns_support = true
    enable_dns_hostnames = true
}

resource "aws_subnet" "tiger" {
    vpc_id = "${aws_vpc.tiger.id}"
    cidr_block = "10.16.0.0/16"
    map_public_ip_on_launch = true
}

resource "aws_internet_gateway" "tiger" {
    vpc_id = "${aws_vpc.tiger.id}"
}

resource "aws_route_table" "public" {
    vpc_id = "${aws_vpc.tiger.id}"

    route {
        cidr_block = "0.0.0.0/0"
        gateway_id = "${aws_internet_gateway.tiger.id}"
    }
}

resource "aws_route_table_association" "jce-public" {
    subnet_id = "${aws_subnet.tiger.id}"
    route_table_id = "${aws_route_table.public.id}"
}

output "vpc_id" {
    value = "${aws_vpc.tiger.id}"
}

output "vpc_subnet_id" {
    value = "${aws_subnet.tiger.id}"
}

We're running into the same problem every now and then and I'm looking forward to having this fixed in TF!

Hey all – the supplied config file applied successfully for me (both creation and deletion). Is it sporadic? You mention race condition, do you have an idea of how often it happens?

[Vlatombe]

Yes it's definitely sporadic. I just checked my CI builds and I would say this happens about 20% of the time.
