Output values after apply in Terraform - Mini Project: Build & Apply

Output values after apply

📖 Scenario: You are setting up a simple cloud infrastructure using Terraform. After creating resources, you want to see important information like the resource ID and IP address once the deployment is done.

🎯 Goal: Create a Terraform configuration that defines a resource and outputs its ID and IP address after applying the configuration.

📋 What You'll Learn

Define a resource with a fixed name

Create output values for resource ID and IP address

Use exact variable and resource names as specified

Outputs must be visible after terraform apply

💡 Why This Matters

🌍 Real World

Cloud engineers often need to see resource details like IDs and IPs after deployment to connect or configure other services.

💼 Career

Knowing how to create and use outputs in Terraform is essential for infrastructure automation and collaboration in cloud roles.

1

Define a simple resource

Create a resource called aws_instance with the name example and set the ami to "ami-12345678" and instance_type to "t2.micro".

Terraform

# Define the aws_instance resource named example
# Your code here

Need a hint?

Use the resource block with type aws_instance and name example. Set the ami and instance_type exactly as shown.

2

Add output for instance ID

Create an output called instance_id that outputs the id attribute of the aws_instance.example resource.

Terraform

resource "aws_instance" "example" {
  ami           = "ami-12345678"
  instance_type = "t2.micro"
}

# Add output for instance_id
# Your code here

Need a hint?

Use an output block with the name instance_id. Set its value to aws_instance.example.id.

3

Add output for public IP

Create an output called public_ip that outputs the public_ip attribute of the aws_instance.example resource.

Terraform

resource "aws_instance" "example" {
  ami           = "ami-12345678"
  instance_type = "t2.micro"
}

output "instance_id" {
  value = aws_instance.example.id
}

# Add output for public_ip
# Your code here

Need a hint?

Use an output block named public_ip and set its value to aws_instance.example.public_ip.

4

Add description to outputs

Add a description attribute to both instance_id and public_ip outputs. Use "The ID of the instance" for instance_id and "The public IP address of the instance" for public_ip.

Terraform

resource "aws_instance" "example" {
  ami           = "ami-12345678"
  instance_type = "t2.micro"
}

output "instance_id" {
  value = aws_instance.example.id
  # Add description here
}

output "public_ip" {
  value = aws_instance.example.public_ip
  # Add description here
}

Need a hint?

Add the description attribute inside each output block with the exact text given.
