failure to create aws_lb network load balancer resource

[drnomolos42]

Hi there,

Thank you for opening an issue. Please note that we try to keep the Terraform issue tracker reserved for bug reports and feature requests. For general usage questions, please see: https://www.terraform.io/community.html.

Terraform Version

esolomon@olmint ~/github/onelogin-terraform-general/prod/haproxy $ terraform -v
Terraform v0.10.7

Affected Resource(s)

Please list the resources as a list, for example:

• aws_lb

If this issue appears to affect multiple resources, it may be an issue with Terraform's core, so please mention this.

Terraform Configuration Files

resource "aws_lb" "primary-nlb-3-subnets" {
  name                  = "primary-nlb"
  count                 = "${length(data.terraform_remote_state.vpc.vpc_subnets_pub) == 3 ? 1: 0}"
  internal              = false
  load_balancer_type    = "network"
  subnet_mapping {
    subnet_id = "${data.terraform_remote_state.vpc.vpc_subnets_pub[0]}"
    allocation_id = "${var.allocation_ids[0]}"
  }
  subnet_mapping {
    subnet_id = "${data.terraform_remote_state.vpc.vpc_subnets_pub[1]}"
    allocation_id = "${var.allocation_ids[1]}"
  }
  subnet_mapping {
    subnet_id = "${data.terraform_remote_state.vpc.vpc_subnets_pub[2]}"
    allocation_id = "${var.allocation_ids[2]}"
  }
}

Debug Output

none

Panic Output

none

Expected Behavior

creating Network Load Balancer

Actual Behavior

Resource never gets created. I've waited up to 20 minutes to see if it completes.

Steps to Reproduce

Please list the steps required to reproduce the issue, for example:

1. terraform apply tf.plan

Important Factoids

I've tried this in several AWS regions with the same behavior. The count conditional is a little hacky but necessary since we have a region with only two subnets active.

References

[drnomolos42]

likely it's same issue reported in a comment in #1912 - using a subnet_mapping causes creation to hang indefinitely.

[radeksimko]

This was addressed in #1956 which was merged and will be available in the next release.
