Create Resource Group

1. Create Azure Resource Group

resource "azurerm_resource_group" "rg-lb" {
name = "rg-terraform-nsg-westusi-lb"
location = "West US 3"
}

2. Create Network Security Group

resource "azurerm_network_security_group" "nsg" {
name = "nsg-terraform-eastus"
location = azurerm_resource_group.rg-lb.location
resource_group_name = azurerm_resource_group.rg-lb.name
}

3. Create inbound rules dynamically using for_each

resource "azurerm_network_security_rule" "inbound" {
for_each = var.inbound_rules

name = each.key
priority = each.value.priority
direction = "Inbound"
access = "Allow"
protocol = "Tcp"

source_port_range = ""
destination_port_range = tostring(each.value.port)
source_address_prefix = var.my_public_ip_cidr
destination_address_prefix = ""

resource_group_name = azurerm_resource_group.rg-lb.name
network_security_group_name = azurerm_network_security_group.nsg.name
}
