terraform-aws-s3

May 6, 2026 · View on GitHub

This ia a Terraform module to provision a secure Terraform S3 bucket. It also has a provisioning test included in its' Github actions so you can be sure each labelled version works.

It's 100% Open Source and licensed under the APACHE2.

Usage

Include this repository as a module in your existing Terraform code:

module "s3" {
  source                  = "JamesWoolfenden/s3/aws"
  version                 = "0.4.0"
  s3_bucket_force_destroy = var.s3_bucket_force_destroy
  s3_bucket_name          = var.s3_bucket_name
  s3_bucket_policy        = data.aws_iam_policy_document.s3_policy.json
}

This creates an S3 bucket with policy and applies the default tags scheme.
