What you will learn

  • Design reusable content with deterministic inputs and clear ownership.
  • Explain preview and secrecy limits without weakening the contract.

  1. Render templates from validated data contracts

    Separate Jinja expressions, native values, controller-side rendering, template trust, and target configuration validation.

    Start learning

  2. Connect truthful changes to handler execution

    Explain notification, deduplication, handler order, listen topics, flush boundaries, and failure implications without restarting services.

    Start learning

  3. Package reusable behavior as role interfaces

    Design role inputs, defaults, tasks, handlers, dependencies, and static versus dynamic reuse with explicit validation.

    Start learning

  4. Pin collections and execution dependencies

    Separate FQCN selection, collection versions, controller dependencies, target requirements, and reproducible execution environments.

    Start learning

  5. Protect secrets across storage and execution

    Distinguish Vault encryption at rest, secret retrieval, no_log, diff suppression, files, and downstream disclosure.

    Start learning

  6. Interpret check mode, diff mode, and tags honestly

    Treat preview modes and task selection as scoped evidence, not a guarantee that a later run is harmless, complete, or correct.
