This lesson focuses on Reading HCL and Building the First Resource Graph and its role in the wider learning Terraform fundamentals through HCL, providers, resources, state, variables, outputs, modules, planning, and safe infrastructure change workflow.
Learners work with the actual design choices, dependencies, controls, and failure modes that distinguish this topic from a generic Terraform exercise.
Build a minimal configuration and trace how references create the dependency graph.
Write and validate a small project with explicit naming and tags.
Configuration is formatted, validates cleanly, and the plan matches the intended resource graph.
Correct syntax errors, provider initialization failures, invalid references, and unexpected dependencies.
Learners isolate the smallest verified cause, correct it, rerun the relevant validation step, and record the preventive action in the course improvement log.
