Lab Information
The Nautilus DevOps team needs to set up an SNS topic for sending notifications. They need to create an SNS topic with the following specifications:
1) The topic name should be devops-notifications.
Use Terraform to create this SNS topic. The Terraform working directory is /home/bob/terraform. Create the main.tf file (do not create a different .tf file) to accomplish this task.
Note: Right-click under the EXPLORER section in VS Code and select Open in Integrated Terminal to launch the terminal.

Step 1: Create Main Terraform Configuration
# main.tf
# Create SNS topic for sending notifications
resource "aws_sns_topic" "devops-notifications" {
name = "devops-notifications"
}
Step2: 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

- 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 deployment to verify 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_sns_topic.devops-notifications will be created
+ resource "aws_sns_topic" "devops-notifications" {
+ arn = (known after apply)
+ beginning_archive_time = (known after apply)
+ content_based_deduplication = false
+ fifo_topic = false
+ id = (known after apply)
+ name = "devops-notifications"
+ name_prefix = (known after apply)
+ owner = (known after apply)
+ policy = (known after apply)
+ signature_version = (known after apply)
+ tags_all = (known after apply)
+ tracing_config = (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.
Output
bob@iac-server ~/terraform via 💠 default ➜ terraform apply
Terraform used the selected providers to generate the following execution plan. Resource
actions are indicated with the following symbols:

}
Plan: 1 to add, 0 to change, 0 to destroy.
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
