terraform-stacks

Orchestrate Terraform modules across environments by grouping them into a Stack using .tfcomponent.hcl files to define sources, inputs, and providers for consistent lifecycle management. This reduces manual effort and drift across dev, staging, and prod.

A Terraform Stack is a declarative configuration layer that groups components and deployments for consistent lifecycle management. You need it to validate and orchestrate infrastructure provisioning across multiple Terraform modules and environments, reducing drift.

Initialize a Terraform Stack by placing a .terraform-version file and at least one .tfcomponent.hcl file in the Stack root, then run terraform stacks init. This prepares the stack for deploying across multiple regions and environments with shared configurations.

Yes, you can use local modules within a Stack deployment by defining them in your .tfcomponent.hcl files. The stack configuration also supports module registries to compose infrastructure across environments and regions.

Troubleshoot Terraform Stack syntax errors by validating your .tfcomponent.hcl and .tfdeploy.hcl file structures. The orchestration layer automates validation to ensure correct configuration across components and deployments before applying changes.

A component is an abstraction around a Terraform module with defined sources and inputs, while a deployment is an instance of all components in a stack across specific environments and regions, managing the complete infrastructure lifecycle.
