Ch.2 webserver cluster instance duplicate error

[alnash28]

Hello @brikis98

While wrapping up Ch.2, I have encountered the following error `Error applying plan:

1 error(s) occurred:

• aws_security_group.instance: Error creating Security Group: InvalidGroup.Duplicate: The security group 'terraform-example-instance' already exists for VPC ' status code: 400, request id: a7232801-b51d-4263-b69a-2ed4f17d08ea

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 am not sure if this related to the version of terraform(see below) or a typo within my main.tf(which I have compared to your examples here)

terraform -v Terraform v0.7.10

Your version of Terraform is out of date! The latest version is 0.10.1. You can update by downloading from www.terraform.io

I updated terraform to 0.9.x per the requirements highlighted within the book, the 0.7.x version was installed previously due to a linux academy course im checking out on the same VM.

terraform -v Terraform v0.9.11

Sorry about that

I should be all set. Towards the end of the chapter, i performed the terraform destroy and re-applied and I seem to be ok,
