Kubernetes Secrets look simple, but they can turn into a security and workflow trap if you treat them like ordinary config. Terraform can manage Secrets (via the Kubernetes provider), but you need to be deliberate about what you store, where it ends up (including Terraform state), and how your team rotates and applies changes.
In the full guide, we cover:
- The different types of Kubernetes Secrets and when to use them
- Creating and managing Secrets with Terraform (including practical examples)
- The biggest gotcha: how secret values can surface in Terraform state and how to reduce exposure
- Patterns for safer automation (separation of concerns, CI/CD handling, and lifecycle considerations)
- Common mistakes teams make when they “Terraform everything” inside the cluster
