Writing configuration for imported resources in Terraform - Mini Project: Build & Apply

Writing configuration for imported resources

📖 Scenario: You have an existing AWS S3 bucket created outside Terraform. You want to manage it using Terraform by importing it and writing the configuration.

🎯 Goal: Create a Terraform configuration that matches the imported AWS S3 bucket resource.

📋 What You'll Learn

Create a Terraform resource block for the S3 bucket named exactly aws_s3_bucket.example.

Add a variable bucket_name with the exact value my-imported-bucket.

Use the variable bucket_name in the resource configuration.

Add a lifecycle block to ignore changes to the acl attribute.

💡 Why This Matters

🌍 Real World

Managing existing cloud resources with Terraform is common when adopting infrastructure as code in teams.

💼 Career

Cloud engineers and DevOps professionals often import resources and write configurations to maintain infrastructure consistency.

1

Define the bucket_name variable

Create a Terraform variable called bucket_name with the default value "my-imported-bucket".

Terraform

# Define the variable bucket_name with default "my-imported-bucket"
# Your code here

Need a hint?

Use the variable block with a default attribute.

2

Create the aws_s3_bucket.example resource block

Create a Terraform resource block named aws_s3_bucket.example that uses the variable bucket_name for the bucket attribute.

Terraform

variable "bucket_name" {
  default = "my-imported-bucket"
}

# Create aws_s3_bucket.example resource using bucket_name variable
# Your code here

Need a hint?

Use resource "aws_s3_bucket" "example" and set bucket = var.bucket_name.

3

Add a lifecycle block to ignore changes to acl

Inside the aws_s3_bucket.example resource block, add a lifecycle block that ignores changes to the acl attribute.

Terraform

variable "bucket_name" {
  default = "my-imported-bucket"
}

resource "aws_s3_bucket" "example" {
  bucket = var.bucket_name
  # Add lifecycle block here
  # Your code here
}

Need a hint?

Use lifecycle { ignore_changes = ["acl"] } inside the resource block.

4

Complete the Terraform configuration for the imported S3 bucket

Ensure the Terraform configuration includes the variable "bucket_name" block and the aws_s3_bucket.example resource block with the lifecycle block ignoring acl changes.

Terraform

# Review and finalize the Terraform configuration
# Your code here
