Error: Role already exists when deploying with Terraform to multiple regions

[jacobfike]

I am using the terraform module for newrelic log ingestion and it deploys fine to the first region, but when trying to deploy to a second region, I get the following error:

Error: failed creating IAM Role (newrelic-log-ingestion): EntityAlreadyExists: Role with name newrelic-log-ingestion already exists

I have tried changing the service_name to include the region, but then I get this error:

Error: unable to load "temp/newrelic-log-ingestion.zip": open temp/newrelic-log-ingestion.zip: no such file or directory

Even changing the service_name, lambda_image_name, and lambda_archive properties to match, it still complains that it cannot find the .zip file.

What needs to be done to allow multi-region deployment through terraform?

@jacobfike Have you tried amending the aws_iam_role to append the region?

[jacobfike]

@mrickard It uses var.service_name as the name of the role, there is not a separate variable for that.

@jacobfike you can override the service_name variable so that it will be unique per region

So would look something like this:

module "newrelic_log_ingestion" {
  source             = "github.com/newrelic/aws-log-ingestion"
  nr_license_key     = "{{YOUR_LICENSE_KEY}}"
  service_name       = "newrelic-log-ingestion-${var.aws_region}"
}
