Terraform Module that implements a CloudFront Distribution (CDN) for a custom origin (e.g. website) and ships logs to a bucket.
If you need to accelerate an S3 bucket, we suggest using terraform-aws-cloudfront-s3-cdn instead.
This project is part of our comprehensive "SweetOps" approach towards DevOps.
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!
Basic usage:
module "cdn" {
source = "git::https://github.com/cloudposse/terraform-aws-cloudfront-cdn.git?ref=master"
namespace = "cp"
stage = "prod"
name = "app"
aliases = ["cloudposse.com", "www.cloudposse.com"]
parent_zone_name = "cloudposse.com"
origin_domain_name = "origin.cloudposse.com"
}Complete example of setting up CloudFront Distribution with Cache Behaviors for a WordPress site: examples/wordpress
Use the AWS cli to request new ACM certifiates (requires email validation)
aws acm request-certificate --domain-name example.com --subject-alternative-names a.example.com b.example.com *.c.example.com
