Warnings on upgrading to Terraform v0.11.1

[horsey]

Warning: output "this_db_parameter_group_arn": must use splat syntax to access aws_db_parameter_group.this attribute "arn", because it has "count" set; use aws_db_parameter_group.this.*.arn to obtain a list of the attributes across all instances

Thanks for reporting! This is an important issue to fix in this and several other AWS modules also.

Probably not related to this issue, but is there a way to pin my infrastructure to a version of the module? I happen to delete my .terraform directory and discovered that I needed to upgrade my Terraform version because it was not compatible with the latest version of the module.

Yes, you can specify version like this:

module "db" {
  source = "terraform-aws-modules/rds/aws"
  version = "v1.4.0"

  # the rest of arguments...
}

Here you can see all releases - https://github.com/terraform-aws-modules/terraform-aws-rds/releases

Thank you!

@antonbabenko Any plans to make a release with the fix?

Thanks in advance.

This is now fixed in v1.5.0
