Welcome to this Infrastructure as Code lesson.
1Core Concepts
This module covers the essential Terraform concepts.
2Step-by-Step Breakdown
The state file (terraform.tfstate) is the most critical part of Terraform. It mapping your configuration to the real-world resources and tracks metadata like resource IDs and dependencies. Pro Tip: Terraform uses State to calculate what needs to be created or deleted.
State files contain everything Terraform knows about your infra, including sensitive data like database passwords and API keys in plain text JSON. Pro Tip: The state file is a security asset; treat it like a secret.
Terraform constantly compares: 1. Your Code (Desired), 2. The State (What K8s thinks), and 3. The Cloud (Actual Reality). If they differ, it plans a change. Pro Tip: State acts as a cache of the 'Real World' to speed up planning.
