terraform-gcp-lab

Hands-on lab repository for the HashiCorp Certified: Terraform Associate (004) — Terraform 1.12, Google Cloud provider.

Every directory is an independent root module built while working through the official learning path. Nothing here is copied: each exercise is run for real against a GCP project, broken on purpose, then repaired. The goal is not to pass a quiz but to know what Terraform does before it does it.

Layout

Directory	Exam objectives	What is exercised
00-get-started/	1, 2, 3	Provider, terraform block, init/plan/apply/destroy, variables, outputs — the official Get Started – Google Cloud collection
01-state/	6, 7	GCS remote backend with locking, state list/show/mv/rm, import (command and block), -refresh-only, -replace, drift detection, lock file breakage and recovery
02-modules/	4, 5	Local versioned module, for_each vs count, dynamic, variable validation, lifecycle (create_before_destroy, ignore_changes, replace_triggered_by, prevent_destroy), pre/postconditions, check, moved / removed, ephemeral & write-only values
03-hcp/	8	Migration GCS → HCP Terraform, CLI-driven then VCS-driven workflow, projects, variable sets, run triggers, policy

Conventions

• One root module per directory, no shared state between them.
• .terraform.lock.hcl is committed (reproducible provider versions). State files and *.tfvars never are.
• Provider pinned with a ~> constraint; Terraform version pinned with required_version.
• Every directory has a NOTES.md: what was tried, what broke, what the fix was, and the exam-relevant takeaway.
• terraform fmt -check and terraform validate pass before any commit.

Running

export GOOGLE_PROJECT=<project-id>
export GOOGLE_REGION=europe-west1
gcloud auth application-default login

cd 00-get-started/<tutorial>
terraform init
terraform plan -out=tfplan
terraform apply tfplan
terraform destroy

Nothing in this repo is meant to stay up. destroy is part of every exercise.
