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!
IMPORTANT: The master branch is used in source just as an example. In your code, do not pin to master because there may be breaking changes between releases.
Instead pin to the release tag (e.g. ?ref=tags/x.y.z) of one of our latest releases.
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
