11-13: Make AWS region configurable via variableThe region is hardcoded. Consider making it configurable through a variable to support different deployment environments.
+variable "aws_region" { + description = "AWS region for all resources" + type = string + default = "us-west-2" +} provider "aws" { - region = "us-west-2" + region = var.aws_region }day02/solution.md (2)
52-77: Enhance testing configuration section with security and state management guidanceThe testing configuration section should include important security considerations and state management best practices.
Add the following sections before the testing steps:
### Important Security Considerations - Never commit sensitive credentials to version control - Use remote state storage (e.g., S3 + DynamoDB) for team collaboration - Enable state encryption at rest - Use state locking to prevent concurrent modifications ### State Management ```terraform terraform { backend "s3" { bucket = "terraform-state-bucket" key = "day02/terraform.tfstate" region = "us-west-2" encrypt = true dynamodb_table = "terraform-state-lock" } }
80-98: Add output values to the example configurationThe example configuration should demonstrate how to use output values to expose important resource attributes.
Add output values to the example:
output "bucket_id" { description = "The name of the bucket" value = aws_s3_bucket.example.id } output "bucket_arn" { description = "The ARN of the bucket" value = aws_s3_bucket.example.arn }🧰 Tools

1-13: Add provider authentication configuration
The AWS provider block is missing authentication configuration. While it might use default credentials, it's better to explicitly document the authentication method in the configuration.
Consider adding explicit provider authentication configuration:
provider "aws" {
region = var.aws_region
# Choose one of the following authentication methods:
# 1. Shared credentials file
shared_credentials_files = ["~/.aws/credentials"]
profile = "default"
# 2. Environment variables (recommended for CI/CD)
# AWS_ACCESS_KEY_ID and AWS_SECRET_ACCESS_KEY
# 3. IAM role (recommended for EC2 instances)
# assume_role {
# role_arn = "arn:aws:iam::ACCOUNT_ID:role/ROLE_NAME"
# }

Add validation block for S3 bucket naming rules
While the variable definition is good, S3 bucket names must follow strict AWS naming rules. Consider adding a validation block to ensure compliance with AWS S3 bucket naming conventions.
variable "bucket_name" {
description = "The name of the S3 bucket"
type = string
default = "my-default-bucket"
+ validation {
+ condition = can(regex("^[a-z0-9][a-z0-9-]{1,61}[a-z0-9]$", var.bucket_name))
+ error_message = "S3 bucket name must be between 3 and 63 characters, contain only lowercase letters, numbers, and hyphens, and cannot start or end with a hyphen."

💡 Codebase verification
Update AWS provider version to the latest stable release (5.79.0)
The current AWS provider version (5.65.0) is outdated. The latest stable version available from the Terraform Registry is 5.79.0. Updating to the latest version ensures access to bug fixes, security patches, and new features.
- Update the version constraint in
day01/solution.md:
terraform {
required_providers {
aws = {
source = "hashicorp/aws"
version = "5.79.0"
}
}
}🔗 Analysis chain
Verify AWS provider version and add security best practices
The AWS provider version is pinned to 5.65.0. While version pinning is good practice, we should verify if this is the latest stable version.
Additionally, consider adding security best practices:
- Mention using AWS Vault or similar tools for secure credential management
- Add a note about following the principle of least privilege when assigning IAM policies
🏁 Scripts executed
The following scripts were executed for the analysis:

This PR covers the implementation of Terraform configurations using HCL syntax as part of TerraWeek Day 2 tasks. The following changes are included:
resourceandproviderfor creating an AWS S3 bucket.variables.tffile to define the variablebucket_name, which is then used in themain.tffile to dynamically configure the S3 bucket name.providerblock.terraform plan, and apply the configuration usingterraform apply.Screenshots from the execution of the
terraform init,terraform plan, andterraform applycommands are included in the PR.This work helps establish a solid foundation for creating and managing infrastructure using Terraform and HCL syntax.
