![]() This will not allow both spoke networks to communicate with each other, only to the hub network.įor the peering connection we will place that code in a file called main.tf. We will be creating a peering connection from the hub to both spoke networks. Now that we have all three networks provisioned out, we’ll need some more terraform code to get the peering connection created between the 3 networks. Resource "azurerm_virtual_network" "hubnetwork" Creating a peering connection in azure using terraform This code below will create an azure virtual network and a subnet : The purpose of this step is to set up top level shared folders, monitoring & networking projects, organization-level logging, and set baseline security settings through organizational policy. In your folder and editor of choice place these 3 files. If you don’t already have your terraform folder created for your hub and spoke environment now would be a good time. The reason is because azure always reserves 3 ip addresses from the space. This give each vnet the ability to create up to 251 resources that need a private ip address. Then the test vnet will create a subnet that utilizes the 10.1.0.1.24.The dev vnet will create a subnet utilizing the 10.0.1.0/24.hub vnet will create a subnet utilizing the 10.2.1.0/24.Each subnet will get a portion of their vnets ip space. ![]() An overlap in the address space will prevent the ability to create a peering connection down the road. Now that we have all three networks cidr ranges separated, we can now confirm that none of these ip ranges will overlap. And last the test vnet will get the 10.1.0.0/16 address rangeīuild subnets in azure for a hub and spoke network.The dev vnet will get the 10.0.0.0/16 address range.Hub vnet will get the 10.2.0.0/16 address range.This is what we will allocate to each vnet: A bastion resides in a public subnet and establishes the network infrastructure needed to connect a user. A bastion provides secured, public access to target resources in the cloud that you cannot otherwise reach from the internet. The smallest range you can make a vnet is a /16 which gives you 65,536 ip addresses to allocate into different subnets. This resource provides the Bastion resource in Oracle Cloud Infrastructure Bastion service. Often we have to provision EC2 instances as bastion hosts and then we run ansible playbooks or init scripts to install packages or configure the system. Since we are creating a hub and spoke network, we need each network space to be unique. The problem comes if you utilize the same cidr ranges and then need to connect to another network. Think of each virtual network as a separate building or company thats not connected. It's 100 Open Source and licensed under the APACHE2. This project is part of our comprehensive 'SweetOps' approach towards DevOps. This is because of the nature of how azure separates each vnet. Terraform module to define a generic Bastion host with parameterized userdata and support for AWS SSM Session Manager for remote access with IAM authentication. Virtual networks in azure are allowed to use the same rfc1918 addresses. Full Video of Hub and Spoke Network Deployment Allocating address space for your virtual networks in azure
