Terraform (AWS)

Last updated Apr 21, 2026 You must generate an Access Key before getting started. All examples will utilize access_key_id and access_key_secret variables which represent the Access Key ID and Secret Access Key values you generated.

This example shows how to configure R2 with Terraform using the AWS provider ↗︎.

Note for using AWS provider

For using only the Cloudflare provider, see Terraform.

With terraform ↗︎ installed:

  1. Create main.tf file, or edit your existing Terraform configuration
  2. Populate the endpoint URL at endpoints.s3 with your Cloudflare account ID
  3. Populate access_key and secret_key with the corresponding R2 API credentials.
  4. Ensure that skip_region_validation = true, skip_requesting_account_id = true, and skip_credentials_validation = true are set in the provider configuration.
terraform {
  required_providers {
    aws = {
      source = "hashicorp/aws"
      version = "~> 5"
    }
  }
}

provider "aws" {
  region = "us-east-1"

  access_key = <R2 Access Key>
  secret_key = <R2 Secret Key>

    # Required for R2.
    # These options disable S3-specific validation on the client (Terraform) side.
  skip_credentials_validation = true
  skip_region_validation      = true
  skip_requesting_account_id  = true

  endpoints {
    s3 = "https://<account id>.r2.cloudflarestorage.com"
  }
}

resource "aws_s3_bucket" "default" {
  bucket = "<org>-test"
}

resource "aws_s3_bucket_cors_configuration" "default" {
  bucket   = aws_s3_bucket.default.id

  cors_rule {
    allowed_methods = ["GET"]
    allowed_origins = ["*"]
  }
}

resource "aws_s3_bucket_lifecycle_configuration" "default" {
  bucket = aws_s3_bucket.default.id

  rule {
    id     = "expire-bucket"
    status = "Enabled"
    expiration {
      days = 1
    }
  }

  rule {
    id     = "abort-multipart-upload"
    status = "Enabled"
    abort_incomplete_multipart_upload {
      days_after_initiation = 1
    }
  }
}

You can then use terraform plan to view the changes and terraform apply to apply changes.
