Terraform: aws_autoscaling_group: diffs didn't match during apply

[chaffees]

During the "terraform apply" step I encountered a bug when it was creating the aws_autoscaling_group. "aws_autoscaling_group: diffs didn't match during apply".

Terraform Version

Terraform Version: 0.11.10

Terraform Configuration Files

resource "aws_autoscaling_group" "tf-public-asg" {
  launch_configuration      = "${aws_launch_configuration.terraform-public-lc.id}"
  availability_zones        = ["${var.availability_zone_a}", "${var.availability_zone_b}"]
  name                      = "tf-public-asg"
  vpc_zone_identifier       = ["${aws_subnet.Subnet_A_Public.id}", "${aws_subnet.Subnet_B_Public.id}"]
  min_size                  = "${var.asg_min_pubic}"
  max_size                  = "${var.asg_max_public}"
  desired_capacity          = "${var.asg_desired_capacity_public}"

  tags {
      key                   = "Name"
      value                 = "tf-public-asg"
      //value                 = "${var.public_instance_name}-${count.index}"
      propagate_at_launch   = true
  }
}

Debug Output

Gist Description: Terraform ASG Bug Output
https://gist.github.com/chaffees/4ae9af18d24fa9e0dd13bca5f6ffd4be

Expected Behavior

ASG should have deployed instances into two AZ's.

Actual Behavior

ASG was not created and no instances were created.

Additional Context

Terraform is running from command line.

Doing some debugging I commented out the "availability_zones" and then reran "terraform apply" and the issue went away. There seems to be some sort of conflict when defining both "availability zones" and "vpc_zone_identifier". Commenting out "availability_zones" seems to be a workaround for now.

Hi @apparentlymart , I would like to work on this.

From the docs at https://www.terraform.io/docs/providers/aws/r/autoscaling_group.html#availability_zones i could see that "availability_zones should not be specified when using vpc_zone_identifier". so rather than failing , should it return an error saying the same?

Ideal behaviour in my opinion would be to able to specify both "availability_zones" and "vpc_zone_identifier" and fail if the subnets provided are not in the available zones provided.

[apparentlymart]

Hi @praveensastry,

If that is indeed the root cause here then it suggests a missing validation rule in the AWS provider, so it might be possible to fix it over there. We've been defaulting to blaming the provider SDK for this class of bug because it seems like it's often the cause, but that might not be true for this one so if adding some additional validation over in the AWS provider to prevent these from being used together is able to fix this problem then that'd be great! Changes to the AWS provider would need to be submitted through its own repository.

Getting same error. Huge horrible debug follows

Also include as much context as you can about your config, state, and the steps you performed to trigger this error.




Terraform does not automatically rollback in the face of errors.
Instead, your Terraform state file has been partially updated with
any resources that successfully completed. Please address the error
above and apply again to incrementally change your infrastructure.

I ran a terraform destroy, then a terraform apply to get to this error.

I'm using Terraform Remote State:

$ cat backends.tf
# Using a single Consul Cluster means we use a single workspace:
terraform {
  backend "remote" {
    hostname = "app.terraform.io"  ##  DO NOT CHANGE
    organization = "quorfgames"  ##  CHANGE TO YOUR DESIRED ORG

    workspaces {
      name = "nathanconsul-dev"  ## https://app.terraform.io/app/looker/workspaces/nathanconsul-dev
      ## NOTE: If using multiple Consul clusters, e.g. dev and prod1, instead of name = "consul-dev", use prefix = "consul-"
      ##       See comments below for further details and an example.
    }

#    workspaces {
#      prefix = "consul-"  ## CHANGE THIS TO YOUR DESIRED WORKSPACE PREFIX
#      ##       If used instead of the above workspaces {} stanza, this 
#      ##       workspaces {} stanza will give you multiple 
#      ##       workspaces, which you can navigate using the commands
#      ##       terraform workspace list
#      ##       terraform workspace select dev    ##  Selects workspace consul-dev
#      ##       terraform workspace create prod1  ##  Creates workspace consul-prod1
#      ##          and
#      ##       terraform workspace select prod1  ##  Selects workspace consul-prod1
#    }
  }
}

Afterwards, I ran this:

terraform plan -var-file=terraform.dev.tfvars -out=terraform.dev.tfplan
terraform apply "terraform.dev.tfplan"

[v6]

That succeeded.

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
