Resource block syntax in Terraform - Mini Project: Build & Apply

Resource block syntax

📖 Scenario: You are setting up a simple cloud infrastructure using Terraform. You want to create a virtual machine instance on a cloud provider.

🎯 Goal: Build a Terraform configuration with a resource block that defines a virtual machine instance with specific properties.

📋 What You'll Learn

Create a resource block for an aws_instance named example

Set the ami attribute to "ami-0c55b159cbfafe1f0"

Set the instance_type attribute to "t2.micro"

Add a tags block with key Name and value ExampleInstance

💡 Why This Matters

🌍 Real World

Terraform resource blocks are the building blocks for defining cloud infrastructure in code. This skill helps automate cloud resource creation.

💼 Career

Cloud engineers and DevOps professionals use Terraform resource blocks daily to manage infrastructure efficiently and reliably.

1

Create the resource block skeleton

Write a Terraform resource block for an aws_instance named example with empty curly braces {}.

Terraform

# Write the resource block header for aws_instance named example
# Your code here

Need a hint?

Start with resource "aws_instance" "example" { } to define the resource block.

2

Add AMI and instance type

Inside the resource "aws_instance" "example" block, add the attribute ami set to "ami-0c55b159cbfafe1f0" and the attribute instance_type set to "t2.micro".

Terraform

resource "aws_instance" "example" {
  # Add ami and instance_type attributes here
  # Your code here
}

Need a hint?

Use ami = "ami-0c55b159cbfafe1f0" and instance_type = "t2.micro" inside the resource block.

3

Add tags block

Inside the resource "aws_instance" "example" block, add a tags block with a key Name and value ExampleInstance.

Terraform

resource "aws_instance" "example" {
  ami           = "ami-0c55b159cbfafe1f0"
  instance_type = "t2.micro"
  # Add tags block here
  # Your code here
}

Need a hint?

Use a tags block with Name = "ExampleInstance" inside the resource block.

4

Complete the resource block

Ensure the resource "aws_instance" "example" block is properly closed with a closing curly brace } and all attributes are correctly indented.

Terraform

resource "aws_instance" "example" {
  ami           = "ami-0c55b159cbfafe1f0"
  instance_type = "t2.micro"

  tags = {
    Name = "ExampleInstance"
  }
  # Close the resource block here
  # Your code here
}

Need a hint?

Make sure the resource block ends with a closing curly brace }.
