Change firewall rules using Terraform and Cloud Shell

🛡️ Automate Firewall Rules with Terraform and Google Cloud Shell | Step-by-Step Lab Tutorial Firewall rules are a crucial layer of defense in any cloud environment. In this step-by-step tutorial, you'll learn how to automate the provisioning of firewall rules and a VPC network using Terraform and Google Cloud Shell. Whether you're a beginner or exploring Infrastructure as Code (IaC) for cloud security, this hands-on video will walk you through a real-world scenario to help you understand and manage network security with consistency and automation. 📌 What you’ll learn: Why firewall rules are critical in cloud environments How to use Terraform to configure and manage firewall rules How Cloud Shell simplifies deployment and management Version-controlled infrastructure with repeatable scripts 🧪 Step-by-step walkthrough: ✅ Task 1: Clone the Terraform repository Launch Google Cloud Shell Run a pre-configured command to clone the Terraform examples repo: cloudshell_open --repo_url "https://github.com/terraform-google-modules/docs-examples.git" --print_file "./motd" --dir "firewall_basic" --page "editor" --tutorial "./tutorial.md" --open_in_editor "main.tf" --force_new_clone Explore the main.tf file containing the VPC and firewall rule configurations ✅ Task 2: Deploy the VPC and firewall Set your Google Cloud project Initialize Terraform (terraform init) Apply the configuration (terraform apply) to create: A custom VPC network A firewall rule allowing ICMP and TCP (ports 80, 8080, 1000–2000) Confirm deployment with Terraform’s output ✅ Task 3: Verify resources Use the Google Cloud Console to check the created VPC and firewall rules See how unique names are dynamically generated with ${local.name_suffix} 💡 Why this matters: Using Terraform with Cloud Shell ensures your firewall and network configurations are consistent, scalable, and easy to maintain. Automating these tasks helps reduce manual errors and improves your cloud infrastructure security posture. 🔔 Subscribe for more tutorials on Terraform, Google Cloud, and Infrastructure as Code.
