Redirect bare domains to www-domains with HSTS using CloudFlare

terraform-aws-redirect

Sets up redirections using AWS CloudFront and Lambda@Edge.

Redirects bare domains to www domains, e.g.:

example.com -> www.example.com

It also makes sure HSTS is on (non-trivial when using CloudFront or similar balancers).

Can also set up alias domains, e.g.:

www.example.com.ar -> www.example.ar
www.olddomain.com -> www.newdomain.com

Again, HSTS headers are set. Redirections are set in a way that they comply with the requirements for HSTS preloading (e.g.: redirecting HTTP to HTTPS in the right order).

Terraform versions

Originally written on Terraform 0.14. Currently used with Terraform 0.15.

Usage

Full example:

module "redirect" {
  source = "terraform-awsredirect"

  domains       = ["example.com", "anotherexample.com"]
  alias_domains = {"example.com.ar": "example.ar"}
}

No aliases:

module "redirect" {
  source = "terraform-awsredirect"

  domains       = ["example.com", "anotherexample.com"]
}

Providers

This module will use its own provider set to us-east-1, since CloudFront and related resources MUST exist in that region.
