Welcome to the Terraform configuration repository for deploying infrastructure on Google Cloud Platform (GCP). This README provides a detailed overview of the activated services, current configurations, and guidelines for managing the infrastructure using Terraform.

Our Terraform configuration enables the following services on GCP:

• Compute Engine API
• VPC (Virtual Private Cloud)
• Firewall
• Service Networking API
• Cloud Build API
• Cloud Functions API
• Cloud Logging API
• Eventarc API
• Cloud Pub/Sub API
• Cloud Run Admin API

Here is an overview of our current infrastructure configuration:

• Region: us-east1
• Zone: us-east1-b
• IP CIDR Range for Web Application: 69.4.20.0/24 -> 10.1.0.0/24
• IP CIDR Range for Database: 4.20.69.0/24 -> 10.2.0.0/24
• Firewall Rules: Allow traffic to port 6969
• Compute Instance Custom Image: webapp-centos-stream-8-a4-v1-20240227204431

To manage the infrastructure, follow these steps:

1. Initialize Terraform

   • Execute terraform init to initialize the Terraform modules and prepare the working directory.

2. Validate Configuration

   • Run terraform validate to check the syntax and consistency of the configuration files.

3. Plan Infrastructure Changes

   • Use terraform plan to preview the changes that Terraform will apply to the infrastructure based on the current configuration.

4. Apply Changes

   • Execute terraform apply to implement the changes defined in the configuration files. This command will create or update the resources on GCP.

• IP Range Selection: Proper selection of IP ranges is essential for maintaining connectivity with GCP's internal services.
• Network Segmentation: Adjusted subnet configurations to avoid conflicts and improve network segmentation.
• Enhanced Connectivity: Implemented VPC peering and Serverless VPC connectors to facilitate better service connectivity.
• Infrastructure Image Path: Ensured consistency by updating the image path for building new infrastructure.
• Cloud SQL Security: Enhanced the security of Cloud SQL instances by configuring them with private IP addresses.
• Connectivity Solutions: Utilized Private Service Access (PSA) and VPC peering for secure and private intra-VPC connections.
• Private Service Connect (PSC): Configured PSC for secure private connectivity within the VPC network.
• Firewall Tagging: Improved network security by applying firewall rules based on tags.

By following these best practices and continuous learning, we aim to maintain a secure and efficient infrastructure on Google Cloud Platform.

We hope this README provides a clear and comprehensive guide for managing GCP infrastructure with Terraform. For further assistance or inquiries, please refer to the documentation or contact our team. Happy deploying!
