Remove the availability_zones from the aws_autoscaling_group definition as a work-around (since they can be derived from the vpc_zone_identifier). I've got some notes about the cause in https://github.com/terraform-providers/terraform-provider-aws/issues/1630.

Hey @davidgenn do you by chance have a configuration that reproduces this that you could share? Please be sure not to share any secrets if you do.

I've been experiencing this as well.

The main auto scaling group configuration looks like this:

resource "aws_launch_configuration" "controller" {
  provider                    = "aws.${var.region}"
  name                        = "${var.name}"
  image_id                    = "${var.image}"
  instance_type               = "${var.machine_type}"
  user_data                   = "${data.template_file.controller.rendered}"
  associate_public_ip_address = false
  iam_instance_profile        = "${aws_iam_instance_profile.controller.id}"
  security_groups             = ["${aws_security_group.controller.id}"]
  key_name                    = "${var.key_name}"

  root_block_device {
    volume_type = "gp2"
    volume_size = "${var.disk_size}"
  }
}

resource "aws_autoscaling_group" "controller" {
  provider              = "aws.${var.region}"
  name                  = "${aws_launch_configuration.controller.name}"
  launch_configuration  = "${aws_launch_configuration.controller.name}"
  desired_capacity      = "${var.servers}"
  min_size              = "${var.servers}"
  max_size              = "${var.servers}"
  availability_zones    = ["${var.zones}"]
  vpc_zone_identifier   = ["${var.private_subnet_ids}"]
  load_balancers        = ["${module.controller_lb.lb_name}"]

  tag {
    key   = "Name"
    value = "${var.name}-${var.region}-${var.machine_type}"
    propagate_at_launch = true
  }

  tag {
    key   = "Type"
    value = "${var.name}"
    propagate_at_launch = true
  }

  tag {
    key   = "Machine"
    value = "${var.machine_type}"
    propagate_at_launch = true
  }
}

I notice that running terraform apply for the first time causes this error but running it the next time works.

Hi, we've been experiencing the same issue using v0.9.11 when creating an aws_emr_instance_group. A gist of the error can be found here.

Also seeing this one in version 0.10.0, here's a gist of the debug output:

https://gist.github.com/rockholla/4bf918d132f32abb73a25f8c09adf73c

And related config for the auto scaling group:

resource "aws_autoscaling_group" "main" {
  name = "${var.name}-scaling"

  availability_zones   = ["${var.availability_zones}"]
  vpc_zone_identifier  = ["${var.subnet_ids}"]
  launch_configuration = "${aws_launch_configuration.main.id}"
  min_size             = "${var.min_size}"
  max_size             = "${var.max_size}"
  desired_capacity     = "${var.desired_capacity}"
  termination_policies = ["OldestLaunchConfiguration", "Default"]

  tag {
    key                 = "Name"
    value               = "${var.name}-host"
    propagate_at_launch = true
  }

  tag {
    key                 = "Cluster"
    value               = "${var.name}"
    propagate_at_launch = true
  }

  tag {
    key                 = "Environment"
    value               = "${var.environment}"
    propagate_at_launch = true
  }

  lifecycle {
    create_before_destroy = true
  }
}

Same issue with autoscaling group in 0.10.0, 0.10.1, 0.10.2

Experiencing similar issues with autoscaling group an 0.10.2

technolithic picture technolithic on 23 Aug 2017

I have been noticing this issue (mismatched diffs for AZ on ASG) as well since 0.10.x. Second terraform apply works fine.

Same here, on 0.10.2.

Trying to create an auto scaling group:

resource "aws_autoscaling_group" "main" {
  name = "rabbitmq"
  launch_configuration = "${aws_launch_configuration.main.name}"
  vpc_zone_identifier = ["${aws_subnet.main.id}"]
  availability_zones = ["${var.availability_zone}"]
  min_size = "${var.scaling_group_min_size}"
  max_size = "${var.scaling_group_max_size}"
  force_delete = false
  load_balancers = ["rabbitmq"]
  health_check_type = "ELB"
  health_check_grace_period = 300

  lifecycle {
    create_before_destroy = true
  }
}

First time running apply produces this output:

* aws_autoscaling_group.main: aws_autoscaling_group.main: diffs didn't match during apply. This is a bug with Terraform and should be reported as a GitHub Issue.

Second time running apply, it works.

Can confirm this behavior. Running apply again makes it work without any errors.

dirkjonker picture dirkjonker on 4 Sep 2017

Can confirm this issue too. Second apply works perfectly(without any other modification).

If needed I can provide my configuration but it's nothing too exotic( ALB + 2 ASGs in 2 AZs).

Remove the availability_zones from the aws_autoscaling_group definition as a work-around (since they can be derived from the vpc_zone_identifier). I've got some notes about the cause in https://github.com/terraform-providers/terraform-provider-aws/issues/1630.

Just encountered this myself, eliminating availability_zones resolved the issue for me. I observed that all the desired availability zones (matching those from the configured subnets) were assigned to the scaling group after creation.

Same here in Terraform v0.11.0 when creating a new auto scaling group (availability_zones is set)

Hi all!

This seems to be the same thing that we discussed over in #17263. Eventually the requester realized that using vpc_zone_identifier instead of availability_zones made the problem go away. I moved the issue over to the provider repository (as terraform-providers/terraform-provider-aws#3439) to see if the AWS provider team can figure out what's going on here, but hopefully this could help you work around this weird bug in the mean time.

👍1

@apparentlymart that doesn't work either, terraform ended up picking a random subnet from a different VPC which ends up with error:

Status Reason: Security group sg-xxxxxx and subnet subnet-yyyyyyy belong to different networks. Launching EC2 instance failed.

This is with terraform 0.11.3

Don't you guys have some kind of regression tests so basic things like this don't brake upon new releases? I saw posts reporting the same issue in 0.10 and 0.9 as well, how is it possible bugs like this to slip through for so long?

Actually for that module I had commented out the vpc_zone_identifier option instead of availability_zones by mistake. Nothing strange when you have to suddenly go and modify every instance of aws_autoscaling_group in 20+ modules. The rest I said above re regression tests and QA still stands.

Hi,

Same issue here.
with 0.11.4

ctaverne picture ctaverne on 20 Mar 2018

I have hit this error too, with Terraform v0.11.7.

There is a gist here with the details.

I was applying a plan containing only 3 resources:

  • 1x EC2
  • 1x extra EBS volume for the EC2
  • 1x volume attachment to the EC2

The EBS volume already existed and was not going to be destroyed, in the plan. It was only going to have some tags updated.

The EC2 and the volume attachment were planned to be destroyed and recreated, because I had made some changes to the user_data script for the EC2.

Please let me know if more context/detail is needed!

Hello!

Thanks for reporting this issue. Unfortunately the error output in this "diffs didn't match" situation is often not enough to diagnose the problem. Starting in 0.12 the situation that causes this error is more precisely reported, and the necessary debugging information is recorded in the logs. If this issue persists after upgrading Terraform, please file an issue with the referenced provider.

Thanks
