What is Terraform AWS S3 Bucket

Terraform, an Infrastructure as Code (IaC) tool, is renowned for its ability to automate and manage infrastructure efficiently. Paired with AWS S3, a highly scalable and durable cloud storage service, Terraform provides a robust solution creates S3 bucket on AWS.

ThreeS3resourcesareofferedbyTerraform:

  • aws_s3_bucket
  • aws_s3_bucket_object
  • aws_s3_bucket_public_access_block

The AWS S3 bucket has various features and functionalities, including support for versioning, replication, encryption, ACL(accesscontrollist), and bucket object policy.

Now, let's dive right in and get started with managing the AWS S3 bucket using Terraform.

How to Create a Terraform AWS S3 Bucket – Example

Creating an S3 bucket using Terraform involves writing configuration files that define the desired state of the S3 bucket. This section will guide you through the process.

Step 1: Create the bucket.tf File

1.Use the following Terraform code snippet in a new Terraform file called main.tf:

provider "aws" { access_key = "${var.aws_access_key}" secret_key = "${var.aws_secret_key}" region = "${var.region}" } module "s3" { source = "" bucket_name = "your_bucket_name" } resource "aws_s3_bucket" "temps3" { bucket = "${var.bucket_name}" acl = "${var.acl_value}" }

Step 2: Create the variables.tf File

The variables.tf file contains the variable references you see in the bucket.tf file. Create a Terraform file with the following code:

variable "bucket_name" {} variable "acl_value" { default = "private" } variable "aws_access_key" { default = “” } variable "aws_secret_key" { default = “”< } variable "region" { default = "region" }

Step 3: Execute the Commands in Terraform

To execute commands in Terraform, you first must initialize it. You can then apply the changes to your environment to create the S3 bucket. Type the following commands in Terraform:

terraform init terraform apply

How to Create S3 Bucket Instances in Terraform

You use the same steps as above to create bucket instances. Follow these steps to create the bucket.tf file and variables.tf file and deploy S3 bucket instances.

Step 1: Create the bucket.tf File

The bucket.tf file stores the basic configurations for the S3 bucket instance. Use the following code in the bucket.tf file:

provider "aws" { access_key = "${var.aws_access_key}" secret_key = "${var.aws_secret_key}" region = "${var.region}" } module "s3" { source = "" bucket_name = "your_bucket_name" } resource "aws_s3_bucket" "temps3" { bucket = "${var.bucket_name}" acl = "${var.acl_value}" }

Step 2: Create the variables.tf File

The variables.tf file contains the variable references you see in the bucket.tf file. Create a Terraform file with the following code:

variable "bucket_name" {} variable "acl_value" { default = "private" } variable "aws_access_key" { default = “” } variable "aws_secret_key" { default = “” } variable "region" { default = "region" }

Step 3: Execute the Commands in Terraform

If you already have Terraform initialized from the previous section, then you do not need to execute it again. If not, you must initialize Terraform before applying environment changes. Type the following commands in Terraform, but exclude the first command if you already have Terraform initialized:

terraform init terraform apply
