Master Terraform Variables for Efficient Cloud Automation! 🚀

📚 Terraform Automation just got more powerful with Class 23! We dove deep into variables and outputs, crucial components that help you define and manage infrastructure efficiently in AWS, Azure, and beyond. 🌐💡

🔑 Key Topics Covered in Class 23:

Local Variables 🏷️: Understand how to declare and use local variables to manage values inside Terraform configuration files.
👉 Example: AWS Automation 1 – Configure EC2 instances and VPCs using local variables.
Output Variables 📊: Learn how to return values from your Terraform configuration to use later or display the outputs.
👉 Example: AWS Automation Output – Display important outputs like public IPs of created instances.
Boolean Variables 🔐: Work with boolean variables to make decisions in your configuration and automate tasks efficiently.
👉 Example: AWS Automation – Toggle features on or off based on boolean flags.
List Variables 📋: Use list variables to store multiple values and iterate over them to deploy resources in bulk.
👉 Example: AWS Automation – Automate deployment of multiple EC2 instances.
Map Variables 🗺️: Harness map variables to store key-value pairs and manage configurations dynamically.
👉 Example: AWS Automation – Configure different instances with unique properties using map variables.
Number Variables 🔢: Automate resource scaling and provisioning with number variables, adjusting based on requirements.
👉 Example: AWS Automation – Scale your infrastructure based on the input number of resources.
String Variables 🧵: Work with string variables to pass dynamic data (like URLs or server names) between Terraform configurations.
👉 Example: AWS Automation – Pass dynamic tags, server names, and URLs for better organization.
