Azure Virtual Network

The module creates Azure Virtual Network with flexible number of subnets, and optionally creates Azure Bastion in the managed Virtual Network.

NOTE: This module is meant to be used with an already created Resource Group.

The module follows Azure naming conventions. Name variables passed to the module are only suffixes used in the full resource names that are defined by Azure standards.

Abbreviations are used for resource names in most cases, based on these Azure recommendations

Define update strategy

Corewide DevOps team strictly follows Semantic Versioning Specification to provide our clients with products that have predictable upgrades between versions. We recommend pinning patch versions of our modules using pessimistic constraint operator (~>) to prevent breaking changes during upgrades.

To get new features during the upgrades (without breaking compatibility), use ~> 2.0 and run terraform init -upgrade

For the safest setup, use strict pinning with version = "2.0.0"

The module creates Azure Virtual Network with flexible number of subnets, and optionally creates Azure Bastion in the managed Virtual Network.

NOTE: This module is meant to be used with an already created Resource Group.

From `v1.x` to `v2.x`

Module from v2.0 has changed naming model of managed resources in accordance with Azure naming conventions, so all resources of the module will be re-created. Also, there is re-named variable name_prefix to name_suffix. Update module inputs following the documentation, and apply changes.

From `v2.x` to `v3.x`

Module from v3.0 has changed Azure Terraform provider version, which isn't compatible with older versions. After the module version is upgraded, re-init the module to upgrade the provider version. Upgrade the Azure provider version at the project level:

 hclterraform {
  required_providers {
    azurerm = {
      source  = "hashicorp/azurerm"
      version = "~> 4.0"
    }
  }
}

Upgrade project dependencies:

 bashterraform init --upgrade

Update the declaration of the module according to the requirements and examples to match the designed configuration, then the configuration can be applied.

Apply the changes to make sure the state of the resources is up-to-date with the new provider version:

 bashterraform apply

From `v3.x` to `v4.x`

Module from v4.0 has changed Azure Terraform provider version, which isn't compatible with older versions. After the module version is upgraded, re-init the module to upgrade the provider version. Upgrade the Azure provider version at the project level:

 hclterraform {
  required_providers {
    azurerm = {
      source  = "hashicorp/azurerm"
      version = "~> 5.0"
    }
  }
}

Upgrade project dependencies:

 bashterraform init --upgrade

Update the declaration of the module according to the requirements and examples to match the designed configuration, then the configuration can be applied.

Apply the changes to make sure the state of the resources is up-to-date with the new provider version:

 bashterraform apply

Create Virtual Network with 2 Subnets packed in different configuration flavors:

Network Security Group and Route Table is created per each Subnet automatically, but without any rules except Azure provisioned defaults. Call these resources later on to attach any custom rules as desired

 hclresource "azurerm_resource_group" "foo" {
  name     = "foo"
  location = "eastus"
}

module "vnet" {
  source  = "solutions.corewide.com/azure/tf-azure-vnet/azurerm"
  version = "~> 2.0"

  name_suffix         = "bar"
  resource_group_name = azurerm_resource_group.foo.name
  region              = azurerm_resource_group.foo.location

  address_space = [
    "10.0.0.0/16",
  ]

  subnets = [
    {
      name_suffix = "baz"

      addresses = [
        "10.0.1.0/24",
      ]
    },
    {
      name_suffix = "biz"

      addresses = [
        "10.0.2.0/24",
      ]

      service_endpoints = [
        "Microsoft.AzureCosmosDB",
      ]
    },
    {
      name_suffix = "qux"
      delegation  = "Microsoft.AzureCosmosDB/clusters"

      addresses = [
        "10.0.3.0/24",
      ]
    },
  ]

  tags = {
    Project = "foo"
  }
}

Create Virtual Network only:

 hclresource "azurerm_resource_group" "foo" {
  name     = "foo"
  location = "eastus"
}

module "vnet" {
  source  = "solutions.corewide.com/azure/tf-azure-vnet/azurerm"
  version = "~> 2.0"

  name_suffix         = "bar"
  resource_group_name = azurerm_resource_group.foo.name
  region              = azurerm_resource_group.foo.location

  address_space = [
    "10.0.0.0/16",
  ]

  tags = {
    Project = "foo"
  }
}

Create Virtual Network with 1 Subnet and Bastion Service:

Bastion Service requires a dedicated Subnet and Public IP that are created within the module. You need to define a valid CIDR pool for that subnet, which requires at least /26 Mask, as in example below

 hclresource "azurerm_resource_group" "foo" {
  name     = "foo"
  location = "eastus"
}

module "vnet" {
  source  = "solutions.corewide.com/azure/tf-azure-vnet/azurerm"
  version = "~> 2.0"

  name_suffix         = "bar"
  resource_group_name = azurerm_resource_group.foo.name
  region              = azurerm_resource_group.foo.location
  bastion_pool        = "10.0.250.0/26"

  address_space = [
    "10.0.0.0/16",
  ]

  subnets = [
    {
      name_suffix = "baz"

      addresses = [
        "10.0.1.0/26",
      ]
    },
  ]

  tags = {
    Project = "foo"
  }
}
