Lab Information
The Nautilus DevOps team is automating IAM role creation using Terraform to streamline permissions management. As part of this task, they need to create an IAM role with specific requirements.
For this task, create an AWS IAM role using Terraform with the following requirements:
The IAM role name iamrole_anita should be stored in a variable named KKE_iamrole.
Note:
The configuration values should be stored in a variables.tf file.
-
The Terraform script should be structured with a main.tf file referencing variables.tf.
The Terraform working directory is /home/bob/terraform.
Right-click under the EXPLORER section in VS Code and select Open in Integrated Terminal to launch the terminal.

Step 1: Create variables.tf
# variables.tf
# Define variable for IAM role name
variable "KKE_iamrole" {
description = "The name of the IAM role to create"
type = string
default = "iamrole_anita"
}
Step 2: Create main.tf
# main.tf
# Create AWS IAM Role with variable reference
resource "aws_iam_role" "this" {
name = var.KKE_iamrole
assume_role_policy = jsonencode({
Version = "2012-10-17"
Statement = [
{
Effect = "Allow"
Principal = {
Service = "ec2.amazonaws.com"
}
Action = "sts:AssumeRole"
}
]
})
tags = {
Name = var.KKE_iamrole
}
}
Step 3: To deploy this configuration
Navigate to the Terraform directory:
cd /home/bob/terraform
Initialize Terraform:
terraform init
Output
bob@iac-server ~/terraform via 💠 default ➜ terraform init
Initializing the backend...
Initializing provider plugins...
- Finding hashicorp/aws versions matching "5.91.0"...
- Installing hashicorp/aws v5.91.0...
- Installed hashicorp/aws v5.91.0 (signed by HashiCorp)
Terraform has created a lock file .terraform.lock.hcl to record the provider
selections it made above. Include this file in your version control repository
so that Terraform can guarantee to make the same selections by default when
you run "terraform init" in the future.
Terraform has been successfully initialized!
You may now begin working with Terraform. Try running "terraform plan" to see
any changes that are required for your infrastructure. All Terraform commands
should now work.
If you ever set or change modules or backend configuration for Terraform,
rerun this command to reinitialize your working directory. If you forget, other
commands will detect it and remind you to do so if necessary.
Plan the configuration:
terraform plan
Output
bob@iac-server ~/terraform via 💠 default ➜ terraform plan
Terraform used the selected providers to generate the following execution plan. Resource
actions are indicated with the following symbols:
+ create
Terraform will perform the following actions:
# aws_iam_role.this will be created
+ resource "aws_iam_role" "this" {
+ arn = (known after apply)
+ assume_role_policy = jsonencode(
{
+ Statement = [
+ {
+ Action = "sts:AssumeRole"
+ Effect = "Allow"
+ Principal = {
+ Service = "ec2.amazonaws.com"
}
},
]
+ Version = "2012-10-17"
}
)
+ create_date = (known after apply)
+ force_detach_policies = false
+ id = (known after apply)
+ managed_policy_arns = (known after apply)
+ max_session_duration = 3600
+ name = "iamrole_anita"
+ name_prefix = (known after apply)
+ path = "/"
+ tags = {
+ "Name" = "iamrole_anita"
}
+ tags_all = {
+ "Name" = "iamrole_anita"
}
+ unique_id = (known after apply)
+ inline_policy (known after apply)
}
Plan: 1 to add, 0 to change, 0 to destroy.
─────────────────────────────────────────────────────────────────────────────────────────
Note: You didn't use the -out option to save this plan, so Terraform can't guarantee to
take exactly these actions if you run "terraform apply" now.
Apply the configuration:
terraform apply
Then type yes when prompted to confirm the creation of the snapshot.

Do you want to perform these actions?
Terraform will perform the actions described above.
Only 'yes' will be accepted to approve.
Enter a value: yes
aws_iam_role.this: Creating...
aws_iam_role.this: Creation complete after 1s [id=iamrole_anita]
Apply complete! Resources: 1 added, 0 changed, 0 destroyed.
