Infoblox Terraform Provider Demo Collection

A comprehensive collection of Terraform demos showcasing how to use the Infoblox Terraform provider for automated IP address management and DNS configuration across multiple cloud providers.

What it does

This repository contains multiple Terraform modules that demonstrate:

• Dynamic IP address allocation from Infoblox address blocks
• Multi-cloud infrastructure provisioning (AWS, Azure, GCP)
• Centralized DNS management across cloud environments
• Automated subnet and VPC creation with Infoblox integration
• Virtual Machine provisioning with dynamic IP assignment

Available Modules

blox42-dns-multi-cloud - Multi-Cloud DNS Management

• Creates DNS A-records for multiple cloud providers in a single configuration
• Manages Azure, AWS, and GCP subzones under a common root DNS zone
• Establishes consistent DNS naming across cloud environments
• Provides centralized DNS management through Infoblox

blox42-vm-next-free-ip-azure - Azure VM with Dynamic IP

• Allocates next available IP address from Infoblox subnet
• Creates Azure Virtual Machine with the allocated IP address
• Creates Azure Network Interface with static IP allocation
• Registers VM hostname and IP in Infoblox IPAM
• Creates DNS A-record for the VM in Infoblox DNS

blox42-vm-next-free-ip-aws - AWS EC2 with Dynamic IP

• Allocates next available IP address from Infoblox subnet
• Creates AWS EC2 instance with the allocated IP address
• Creates AWS Network Interface with static IP allocation
• Registers VM hostname and IP in Infoblox IPAM
• Creates DNS A-record for the VM in Infoblox DNS

blox42-vnet-next-free-subnet-azure - Azure VNet Provisioning

• Allocates next available subnets from Infoblox address blocks
• Creates Azure Virtual Networks and subnets with the allocated CIDR ranges
• Reserves critical IP addresses (.1, .2, .3) for Azure infrastructure
• Synchronizes subnet information between Azure and Infoblox

blox42-vpc-next-free-subnet-aws - AWS VPC Provisioning

• Allocates next available subnets from Infoblox address blocks
• Creates AWS VPCs and subnets with the allocated CIDR ranges
• Reserves critical IP addresses (.1, .2, .3) for AWS infrastructure
• Synchronizes subnet information between AWS and Infoblox

blox42-vpc-next-free-subnet-gcp - GCP VPC Provisioning

• Allocates next available subnets from Infoblox address blocks
• Creates GCP VPCs and subnets with the allocated CIDR ranges
• Reserves critical IP addresses (.1, .2, .3) for GCP infrastructure
• Synchronizes subnet information between GCP and Infoblox

Quick Setup

1. Prerequisites

   • Terraform >= 1.0
   • Cloud provider CLI tools (AWS CLI, Azure CLI)
   • Infoblox CSP account and API key

2. Choose a module

   # Navigate to the desired module directory
   cd blox42-vm-next-free-ip-azure
   # or
   cd blox42-vm-next-free-ip-aws
   # or
   cd blox42-dns-multi-cloud
   # or
   cd blox42-vnet-next-free-subnet-azure
   # or
   cd blox42-vpc-next-free-subnet-aws
   # or
   cd blox42-vpc-next-free-subnet-gcp

3. Configure credentials

   cat > terraform.auto.tfvars << EOF
   csp_url = "https://csp.eu.infoblox.com"
   api_key = "your-infoblox-api-key"
   subscription_id = "your-azure-subscription-id"  # For Azure modules
   EOF

4. Customize settings

   # Edit terraform.tfvars with your configuration
   nano terraform.tfvars

5. Deploy

   terraform init
   terraform plan
   terraform apply

Module Configuration

Each module has its own terraform.tfvars file with example configurations:

• blox42-dns-multi-cloud: DNS zones, subzones, and IP addresses for multi-cloud setup
• blox42-vm-next-free-ip-azure: Azure VM configuration, network settings, and DNS zone
• blox42-vm-next-free-ip-aws: AWS EC2 configuration, network settings, and DNS zone
• blox42-vnet-next-free-subnet-azure: Azure VNet and subnet configuration
• blox42-vpc-next-free-subnet-aws: AWS VPC and subnet configuration
• blox42-vpc-next-free-subnet-gcp: GCP VPC and subnet configuration

Cleanup

# Navigate to the module directory
cd <module-name>
terraform destroy
