4 ways to use Argo CD and Terraform together

Terraform is the most popular solution for implementing Infrastructure As Code (IaC). The Terraform provider registry contains a very large collection of providers/integrations for all the major cloud providers and at the same time offers a wealth of integration for databases, networking components, Continuous Integration platforms etc.

Argo CD is the leading solution for GitOps deployments on Kubernetes. In the last CNCF survey we found out that 60% of respondents use Argo CD in production.

Although several guides currently exist that explain how to use each tool individually, there is limited information on how they can be combined. A lot of existing Terraform users adopt Argo CD and wonder:

1. What is the best way to pass variables from Terraform to Helm charts deployed with Terraform?
2. How to get secrets in Kubernetes applications that are generated/retrieved from Terraform?
3. When should the Terraform Helm and Kubernetes providers come into play if Argo CD already supports Kubernetes deployments on its own?
4. For which Kubernetes resources should Terraform be responsible and for which Argo CD?
5. What is the proper boundary between the two tools so that operators can use them to the maximum benefit?

In this guide, we will answer all these questions and actually show you four different approaches for how Terraform and Argo CD can work together. Note that everything we say about Terraform also applies to OpenTofu.
