Guys,

Maybe I have been a “noobie”…

But I’m not found a way to attach a existent role to EC2 using the official [Terraform Module](https://github.com/terraform-aws-modules/terraform-aws-ec2-instance).

Someone know how workaround in this scenario? I just wanna deplaoy a new EC2 with attached existent IAM Role…

The module has an attribute to allow you to attach an instance profile: [GitHub - terraform-aws-modules/terraform-aws-ec2-instance: Terraform module which creates EC2 instance(s) on AWS 🇺🇦](https://github.com/terraform-aws-modules/terraform-aws-ec2-instance#input_iam_instance_profile)

```auto
Error: creating EC2 Instance: InvalidParameterValue: Value (arn:aws:iam::1234567890:instance-profile/ec2-xxxxxxx) for parameter iamInstanceProfile.name is invalid. Invalid IAM Instance Profile name

```

I’ve tried with:

- IAM ROLE ARN
- IAM ROLE PROFILE

And returns the same error above…

I’ve solved. The parâmeter: `iam_instance_profile` expects exactly the role **name**. Normally the resources waiting for **ARN**.
