Program narrative

Participants build a multi-environment pipeline with policy-as-code gates and human-readable module contracts. You will practice importing legacy resources, documenting state ownership, and communicating changes to application teams without burying them in diffs.

What is included

  • Module design patterns with explicit interfaces
  • Remote state strategies and locking etiquette
  • Policy checks that catch risky destroys early
  • Drift triage workflows and communication templates
  • Secrets handling without sharing long-lived keys in chat
  • Documentation blocks that survive audits
  • Pair sessions on reviewing large plans calmly

Outcomes you can demonstrate

  1. Ship a reusable module with examples and upgrade notes
  2. Run a policy-gated apply demo for stakeholders
  3. Draft a drift response playbook for your squad

FAQ

Terraform or OpenTofu?

Core lessons target Terraform 1.x APIs; OpenTofu compatibility is highlighted where CLI flags differ.

Do you cover cloud-specific modules?

Yes, with emphasis on patterns that stay portable. Vendor-specific modules are demos, not the entire syllabus.

What is excluded?

We skip desktop virtualization stacks and bare-metal provisioning kits. Those belong to a dedicated hardware track.
