SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This Skill helps teams manage Terraform infrastructure reliably by reducing mistakes around state handling, module interfaces, remote backends, and multi-environment workflows.

Core Features & Use Cases

  • State management: Use remote backends, state locking, and workspace or directory-based isolation to prevent corruption and cross-environment drift.
  • Module design: Define clear module inputs/outputs with versioning and documentation so infrastructure code stays reusable and testable.
  • Remote backend + multi-environment strategy: Configure secure S3-style backends, support workspaces and fully isolated directories, and apply changes through a controlled CI workflow (plan in CI, approve, then apply).
  • Example use case: A team needs a repeatable Terraform setup for dev/staging/production that shares modules (e.g., networking, compute, database) while keeping state locked and separated across environments.

Quick Start

Instruct your agent to generate a Terraform repository layout with modules, a remote backend configuration, and a dev/staging/production strategy that uses workspaces or isolated directories.

FAQPage Schema
How do I manage Terraform state safely across multiple environments?

Standardize Terraform multi-environment deployments by configuring remote backends with locking and using workspaces or directory isolation. This prevents state corruption and cross-environment drift across dev, staging, and production.

What is the best way to structure a Terraform repository for dev, staging, and production?

Structure your Terraform repository by defining reusable modules with clear inputs, outputs, and versioning. Combine this with workspace or directory isolation to maintain consistent dev, staging, and production deployments.

How do I set up a CI-driven Terraform plan and apply workflow?

Configure a remote backend and implement a structured CI workflow that runs terraform plan in CI, requires manual approval, and then executes terraform apply. This ensures controlled infrastructure changes across environments.

Does this approach support S3 backends with state locking for infrastructure code?

Yes, this approach supports configuring secure S3-style remote backends with state locking. This prevents concurrent state modifications and ensures your Terraform infrastructure code remains safe and repeatable.

How do I prevent cross-environment drift when using Terraform workspaces?

Prevent cross-environment drift by implementing remote state storage with locking alongside workspace or directory-based isolation. This keeps your Terraform environment states fully separated, secure, and consistent.

When should I use isolated directories instead of workspaces for Terraform state?

Use isolated directories instead of workspaces for Terraform state when you need fully separated configurations for dev, staging, and production. Directory isolation provides stronger boundaries for complex multi-environment workflows.
