Where it comes from, where it leads

What you need to know first, where you stand on this skill, and what it opens next. Your status is computed in your browser, from what you have read and passed.

Before · 1 prerequisite

• Run commands and read their output in a shell

• Set up a hypervisor and check that it works
• Predict what an IaC tool will create, change or destroy: declarative model, idempotence, state and plan

This skill, for you

Initialise, run and troubleshoot a Terraform project, from init to destroy

Computing

It unlocks · 8 skills

• Rebuild a cloud environment from code, instances bootstrapped unattended, then destroy it with nothing left
• Organize a multi-team cloud environment: separate accounts, guardrails as code and tagging
• Test infrastructure code without a cloud account: apply, empty plan and destroy, locally and in CI
• Run and govern Terraform remotely with HCP Terraform
• Parameterize a Terraform project and expose its results without duplicating values
• Declare Terraform resources and data sources with pinned providers
• Share a remote, locked and recoverable Terraform state
• Run Keycloak in production: TLS proxy, restored backup, version upgrade, emergency access and a realm described in Terraform

Beyond the lessons

Assess, practise, pass the proof

Reading a lesson confirms nothing. A skill is confirmed by a passed quiz, practised in a guided lab, and put to the test by a challenge or a mission; an imported lab result is not verified by the site.

Assess yourself

6 quizzes

At the end of the lessons: passed at 70%, they confirm the skill.

Practice

10 guided labs

• Destroying cleanly, and the four things it covers
• Resume after a failed apply, without redoing the work
• First infrastructure: the full cycle, proven
• Make fmt, validate and the outputs agree
• Prove idempotence where the imperative script diverges
• Prove that Terraform has a memory
• Split a monolith without moving the plan
• Prove Terraform / OpenTofu compatibility, and where it stops
• Read a plan before applying it
• The config that works but no CI accepts

Proof

No proof

Neither a challenge nor a mission with a proof yet.

Apply it on real infrastructure

• Première infrastructure Terraform sur KVM (in French)
• Détruire proprement avec Terraform (in French)
• Learn Terraform with no cloud account and no credit card
• Quiz Découvrir Terraform (in French)

Hands-on lessons: their labs count as practice and their quizzes assess you, without being required to acquire it.
