opentofu-coder

OpenTofu is a Terraform fork that uses the same HCL syntax and workflow. Write .tf files declaring providers, resources, and data sources the same way you would in Terraform, then run OpenTofu commands to plan and apply infrastructure changes.

Start with flat, minimal .tf files in a single directory. Use workspace handling for environment separation and backend configuration for state management. Organize reusable modules only when complexity genuinely demands it, avoiding over-engineering.

Create modules by grouping related resources, variables, and outputs into separate directories. Use variable patterns and type constraints to enforce consistency. Reference modules from your main configuration with the module block, parameterizing provider and variable inputs.

Yes. OpenTofu tracks resource state in backends (local, remote, or cloud). Declarative HCL ensures idempotency—running the same configuration repeatedly produces the same result, making infrastructure predictable and reproducible.

No. Start with basic provider and resource blocks for quick deployments. Advanced expressions, type constraints, and complex patterns are available when your infrastructure grows, but flat, simple setups handle most common use cases.

Address workspace handling for environment separation, backend configuration for state storage, variable patterns for reusability, and modular design principles. OpenTofu maintains Terraform compatibility while supporting its own ecosystem and community practices.
