Scaffolding and Code Generation

Catalyst enables a guided flow:

1. Scaffold a Bundle

• Run terramate scaffold to select a Bundle (from local or remote collections) and provide inputs via prompts.
• The command writes a Bundle Instantiation file (HCL or YAML) at the location defined by the bundle’s scaffolding configuration.

2. Generate code

• Run terramate generate. With bundles present, this will:
  • Create Bundle Stacks if they do not already exist
  • Generate Terraform code and files in those stacks
  • Preserve existing stack metadata (stack configuration is not changed)
  • Remove generated code if the bundle instantiation is removed, without deleting stacks

3. Plan/apply with your normal tooling

• The generated code is plain Terraform/OpenTofu and works with your existing pipelines and policy engines.
