Helm is designed to take the guesswork (and a lot of the YAML) out of deploying a Kubernetes application. If you’ve ever needed to rapidly deploy a durable application, you’ve probably taken a long look at a Helm chart. And if you’re already using Helm, you’ve probably considered about how Infrastructure as Code (IaC) can simplify your workflow.
But how does Helm’s configuration interact with IaC state? What configuration is really authoritative—and with what scope? If you update an application that you Terraformed from a Helm chart, is your persistent data safe? And what about existing Helm-deployed applications—is it safe to import them into Terraform?
Clearly, Helm is incredibly powerful, but it’s also an abstraction, and no one has written the manual on how to integrate it with IaC. This talk will explain how Helm and Terraform work together under the hood, as well as exploring patterns to help Terraform practitioners safely engage with Helm charts and adopt Helm resources.
