Terraform module to provision an IAM role for external-dns running in a Kops cluster, and attach an IAM policy to the role with permissions to modify Route53 record sets.
This module assumes you are running external-dns in a Kops cluster.
It will provision an IAM role with the required permissions and grant the Kops masters the permission to assume it.
This is useful to make Kubernetes services discoverable via AWS DNS services.
The module uses terraform-aws-kops-metadata to lookup resources within a Kops cluster for easier integration with Terraform.
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.
