Azure Application Gateway

This repository demonstrates the deployment of an Azure Application Gateway using Terraform. It includes configuration for SSL settings, backend pools with Azure App Services, and redirection of HTTP traffic to HTTPS on behalf of Application gateway. Additionally, Cloudflare DNS records are dynamically created using a specified Terraform provider.

Features

• Azure Application Gateway:

  • Provides HTTPS connection to app services backend node pools
  • Supports routing rules to redirect HTTP (port 80) traffic to HTTPS (port 443) for improved security.

• Cloudflare Integration:

  • Automatically creates and manages DNS records via the Cloudflare Terraform provider, ensuring streamlined domain management.

Steps to configure communication

• Deploy virtual network
• Deploy application gateway subnet
• Deploy application gateway public IP
• Associate gateway with subnet using gateway_ip_configuration block
• Define app gateway frontend ports (80, 443) by using frontend_port block
• Associate app gateway with public IP using frontend_ip_configuration block
• Define backend pools with app services FQDNs by using backend_address_pool block
• Define HTTP settings for routing rules by using http_settings block
• Add http and https listeners to the app gateway using http_listener block
• Define routing rules to handle requests based on headers CN
• Create a Cloudflare DNS record for the app gateway public IP and test connection
