Terraform Infrastructure for GovTool

This repository contains Terraform configurations for managing cloud resources for the GovTool project, focusing on AWS.

Architecture Overview

The infrastructure is designed to support multiple environments and components across the development lifecycle.

Components

  • IAM Groups and Policies: Manage access and permissions for CI/CD processes.
  • DNS Management: Route 53 is used to handle DNS configurations for various services.
  • ECR Repositories: Host Docker images for backend, frontend, and services.
  • EC2 Instances: Support development, testing, staging, and beta environments.

Managed Resources

This project configures and manages several AWS resources essential for the operation and deployment of the GovTool application across various environments.

IAM Configuration

  • IAM Group (CICD): Manages CI/CD permissions.
  • IAM Policy (CICD_ECR): Attached to the CICD group to manage ECR access.

DNS Management

  • Route 53 Zone (govtool.byron.network): Handles DNS configurations and routing for the application.

Container Registry

  • ECR Repositories:
    • backend: Stores backend service images.
    • backend-base: Stores base images for backend development.
    • frontend: Stores frontend service images.
    • status-service: Stores images for the status monitoring service.
    • metadata-validation: Stores images for metadata validation service.
    • analytics-dashboard: Stores images for analytics dashboard.

Compute Resources

  • EC2 Instances:
    • dev: Instance for development.
    • test: Instance for testing.
    • staging: Instance for staging.
    • beta: Instance for beta testing.

Configuration Files

  • main.tf: Defines the provider, resources, and modules for infrastructure management.
  • versions.tf: Specifies the required versions for Terraform and providers, ensuring compatibility.

Managing Infrastructure

Prerequisites

  • AWS CLI
  • Configured AWS credentials
  • Terraform CLI (version specified in versions.tf)

Initialization

Initialize the Terraform environment to begin managing the infrastructure:

terraform init
terraform plan
terraform apply

Adding or Modifying Components

When adding new resources or modifying existing configurations, ensure to follow the modular structure and update the respective environment settings as required.

Continuous Integration and Deployment

IAM configurations and ECR policies are tailored to support CI/CD pipelines, allowing automated build and deployment processes.

Outputs

Terraform outputs are configured to provide URLs and domain names for the deployed services, facilitating easy access and management.

Contributions

Contributions are welcome. Please ensure to maintain the modular architecture and follow best practices for cloud resource management.
