In this talk we'll review best practices for deploying a simple web application to a multi-account/environment using Kubernetes (EKS) in AWS. We'll focus on the DRY (Don't Repeat Yourself) principle. We'll setup the infrastructure using Terraform and use Terragrunt for dynamic Terraform configurations. We'll also be using the Kustomize tool which has been gaining in popularity and handles much of what Helm is commonly used for. We'll be using Kustomize to create Kubernetes templates that are unique for each environment. We'll ensure we're applying the DRY principle to both Terraform and Kubernetes and only distinguishing parameters that are unique for each environment.
