Overview

This Terraform module deploys a complex infrastructure (AWS resources, Datadog monitoring, and a GitHub repository) for demo purposes.

• AWS Infrastructure - Networking (VPC, subnets, NAT Gateway, IGW, etc.), EC2 instances, and an ALB are deployed to support a simple NGINX application.
• Datadog - A basic Datadog monitoring dashboard is deployed, and Datadog is installed on the EC2 instance (via a user data script)
• GitHub - A GitHub repository (a clone of this template repository) is created and the necessary repository secrets are created to support day 2 operations via Cloudify

Variables

The module takes the following variables.

• app_name - The name of the application that is being deployed. This is used to name resources (instances, GitHub repo, Datadog dashboard, etc.)
• aws_access_key - AWS access key ID used for authentication
• aws_secret_key - AWS secret key used for authentication
• datadog_api_key - Datadog API key. Used for authentication and agent configuration
• datadog_app_key - Datadog app key. Used for authentication and agent configuration
• datadog_api_url - URL for the Datadog API (e.g., if using the EU region, specify https://api.datadoghq.eu/)
• github_token - GitHub token. Used to create repository
• cloudify_host - The host of the Cloudify manager. Used to configure secrets in the GitHub repository
• cloudify_user - A user to authenticate with the Cloudify manager. Used to configure secrets in the GitHub repository
• cloudify_password - The password for the cloudify_user. Used to configure secrets in the GitHub repository

Outputs

The module exposes the following outputs:

• lb_dns - DNS endpoint of the ALB deployed in AWS
• dashboard_url - URL to access the Datadog dashboard for the application
• repo_url - URL for the GitHub repository that is created
