Description

AWS permissions boundaries limit the maximum permissions that an identity-based policy can grant to an IAM entity.

How to fix?

Set the permissions_boundary attribute of aws_iam_role or aws_iam_user to the ARN of an IAM policy.

Example Configuration

resource "aws_iam_user" "valid-user-1" {
  name = "valid-user-1"
  
  permissions_boundary = "<iam-policy-arn>"
  # other required fields here
}
resource "aws_iam_role" "valid-role-1" {
  name = "valid-role-1"
  
  permissions_boundary = "<iam-policy-arn>"
  # other required fields here
}
