I am trying to attach an existing role created in AWS, but I am not able to add it in Terraform Code. A short list of benefits over other methods include: Native Terraform configuration - no need to worry about JSON formatting or syntax. With Cluster SG & IAM role everything is all right. Write Terraform configuration files for IAM Role Create a dedicated directory where you can create terraform configuration files. When using these Terraform modules, you must ensure that the IAM user or role with which Terraform commands are executed has the appropriate permissions. This role will later get applied to our Lambda functions.
