Terraform module to provision S3-backed Websites


This project is part of our comprehensive "SweetOps" approach towards DevOps.

Terraform Open Source Modules

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

We literally have hundreds of terraform modules that are Open Source and well-maintained. Check them out!

Usage

IMPORTANT: We do not pin modules to versions in our examples because of the difficulty of keeping the versions in the documentation in sync with the latest released versions. We highly recommend that in your code you pin the version to the exact version you are using so that your infrastructure remains stable, and update versions in a systematic way so that they do not catch you by surprise.

Also, because of a bug in the Terraform registry (hashicorp/terraform#21417), the registry shows many of our inputs as required when in fact they are optional. The table below correctly indicates which inputs are required.

Create s3 website bucket

module "website" {
  source = "cloudposse/s3-website/aws"
  # Cloud Posse recommends pinning every module to a specific version
  # version = "x.x.x"
  namespace = "eg"
  stage     = "prod"
  name      = "app"
  hostname  = "docs.prod.cloudposse.org"

  deployment_arns = {
    "arn:aws:s3:::principal1" = ["/prefix1", "/prefix2"]
    "arn:aws:s3:::principal2" = [""]
  }
}

Create S3 website bucket with Route53 DNS

Required one of the parent_zone_id or parent_zone_name

module "website_with_cname" {
  source = "cloudposse/s3-website/aws"
  # Cloud Posse recommends pinning every module to a specific version
  # version = "x.x.x"
  namespace      = "eg"
  stage          = "prod"
  name           = "app"
  hostname       = "docs.prod.cloudposse.org"
  parent_zone_id = "XXXXXXXXXXXX"
}
