Terraform AZURE SUBNET

Terraform module to create subnet resource on AZURE.

Terraform Licence

Prerequisites

This module has a few dependencies:

IMPORTANT: Since the master branch used in source varies based on new modifications, we suggest that you use the release versions here.

Simple Example

Here is an example of how you can use this module in your inventory structure:

Default Subnet

  module "subnet" {
    source               = "clouddrove/subnet/azure"
    name                 = "app"
    environment          = "test"
    label_order          = ["name", "environment"]
    resource_group_name  = module.resource_group.resource_group_name
    location             = module.resource_group.resource_group_location
    virtual_network_name = join("", module.vnet.vnet_name)

    #subnet
    subnet_names        = ["subnet1", "subnet2"]
    subnet_prefixes     = ["10.0.1.0/24", "10.0.2.0/24"]

    # route_table
    routes = [
      {
        name           = "rt-test"
        address_prefix = "0.0.0.0/0"
        next_hop_type  = "Internet"
      }
    ]
  }

Name_Specific Subnet

  module "name_specific_subnet" {
    source               = "clouddrove/subnet/azure"
    name                 = "app"
    environment          = "test"
    label_order          = ["name", "environment"]
    resource_group_name  = module.resource_group.resource_group_name
    location             = module.resource_group.resource_group_location
    virtual_network_name = join("", module.vnet.vnet_name)

    #subnet
    specific_name_subnet  = true
    specific_subnet_names = "SpecificSubnet"
    subnet_prefixes       = ["10.0.1.0/24"]

    # route_table
    routes = [
      {
        name           = "rt-test"
        address_prefix = "0.0.0.0/0"
        next_hop_type  = "Internet"
      }
    ]
  }

Nat_Gateway Subnet

  module "name_specific_subnet" {
    source               = "clouddrove/subnet/azure"
    name                 = "app"
    environment          = "test"
    label_order          = ["name", "environment"]
    resource_group_name  = module.resource_group.resource_group_name
    location             = module.resource_group.resource_group_location
    virtual_network_name = join("", module.vnet.vnet_name)

    #subnet
    create_nat_gateway  = true
    subnet_names        = ["subnet1", "subnet2"]
    subnet_prefixes     = ["10.0.1.0/24", "10.0.2.0/24"]

    # route_table
    routes = [
      {
        name           = "rt-test"
        address_prefix = "0.0.0.0/0"
        next_hop_type  = "Internet"
      }
    ]
  }
