Run GCP Services Using Terraform

This guide will help you set up Google Cloud services using Terraform. Follow the steps below to configure your environment and execute Terraform commands.

Prerequisites

1. Create a GCP Account and Project

• Sign up for a Google Cloud Platform (GCP) account if you don't have one.
• Create a new GCP project.

2. Set Up a Service Account

• Create a service account with the following roles:
  • Storage Admin
  • BigQuery Admin
  • Compute Admin
    (Note: These permissions are overly broad for production environments; they are assigned here for demonstration purposes.)

3. Download Service Account Credentials

• Download the service account key file (JSON format) and store it securely.
• Add the path to the credentials file in the variables.tf file.

Terraform Commands

Use the following Terraform commands to manage your infrastructure:

1. terraform init

   • Initializes and configures the backend, installs necessary plugins/providers, and checks out the existing configuration from version control.

2. terraform plan

   • Previews local changes against the remote state and generates an execution plan.

3. terraform apply

   • Prompts for approval and applies the changes to the cloud infrastructure based on the execution plan.

4. terraform destroy

   • Removes all the resources defined in your configuration from the cloud.
