部署

所有 Terraform 檔案均位於 terraform/ 目錄中。複製儲存庫並直接部署：

git clone https://github.com/f5-sales-demo/traffic-generator.git
cd traffic-generator/terraform
cp terraform.tfvars.example terraform.tfvars
# Edit terraform.tfvars with your Azure subscription ID and target FQDN

Terraform 設定

Terraform 檔案結構

terraform 目錄包含 9 個遵循示範資源標準的檔案：

versions.tf — Terraform 與提供者版本限制（azurerm ~> 4.0、azuread ~> 3.0）
providers.tf — Azure RM 與 Azure AD 提供者設定
data.tf — 用於部署者自動解析的 Azure AD 資料來源
locals.tf — 部署者解析、Azure Cloud Adoption Framework 資源命名、標準標籤
main.tf — 資源群組（命名為 rg-traffic-generator-{environment}-{deployer}）
variables.tf — 所有輸入變數（2 個必填、9 個選填），透過 Azure AD 進行部署者自動解析
network.tf — VNet（10.201.0.0/16）、子網路、公用 IP、NSG（連接埠 22 SSH）、NIC
vm.tf — 透過 templatefile() 使用 cloud-init 的 Ubuntu 24.04 VM
outputs.tf — 17 個輸出：15 個所有示範資源共用的標準輸出（deployer、public_ip、private_ip、ssh_command、resource_group_name、vm_name、nsg_name、vnet_name、subnet_id、component、environment、resource_group_id、vm_id、nsg_id、location），以及 2 個元件專屬輸出（target_fqdn、status_check）

提供者與變數

main.tf 設定 Azure 提供者：

resource "azurerm_resource_group" "main" {
  name     = local.name.resource_group
  location = var.location
  tags     = local.tags
}

variables.tf 定義所有可設定參數。vm_size 預設值為 Standard_F16s_v2（16 vCPU 計算最佳化）— 請參閱 VM 規格調整以了解擴充指引：

網路基礎架構

network.tf 建立 VNet、子網路、公用 IP、NSG（連接埠 22 SSH）及 NIC：

resource "azurerm_virtual_network" "main" {
  name                = local.name.virtual_network
  address_space       = ["10.201.0.0/16"]
  location            = azurerm_resource_group.main.location
  resource_group_name = azurerm_resource_group.main.name

  tags = azurerm_resource_group.main.tags
}

resource "azurerm_subnet" "main" {
  name                 = local.name.subnet
  resource_group_name  = azurerm_resource_group.main.name
  virtual_network_name = azurerm_virtual_network.main.name
  address_prefixes     = ["10.201.1.0/24"]

resource "azurerm_network_security_group" "main" {

  location            = azurerm_resource_group.main.location
  resource_group_name = azurerm_resource_group.main.name

  security_rule {

    access                     = "Allow"
    protocol                   = "Tcp"
    source_port_range          = "*"
    destination_port_range     = "22"
    source_address_prefix      = "*"
    destination_address_prefix = "*"

    private_ip_address_allocation = "Dynamic"
    public_ip_address_id          = azurerm_public_ip.main.id

  network_security_group_id = azurerm_network_security_group.main.id
}

搭配 Cloud-Init 的虛擬機器

vm.tf 建立 Ubuntu 24.04 VM，並傳遞包含目標及工具變數的 cloud-init 範本：

resource "azurerm_linux_virtual_machine" "main" {
  name                = local.name.virtual_machine
  resource_group_name = azurerm_resource_group.main.name
  location            = azurerm_resource_group.main.location
  size                = var.vm_size

  admin_username                  = var.admin_username
  disable_password_authentication = true

  admin_ssh_key {
    username   = var.admin_username
    public_key = file(pathexpand(var.ssh_public_key_path))
  }

  network_interface_ids = [azurerm_network_interface.main.id]

  os_disk {
    caching              = "ReadWrite"
    storage_account_type = "Premium_LRS"
    disk_size_gb         = var.disk_size_gb
  }

  source_image_reference {
    publisher = "Canonical"
    offer     = "ubuntu-24_04-lts"
    sku       = "server"
    version   = "latest"
  }

  custom_data = base64encode(templatefile("${path.module}/cloud-init.yaml", {
    target_fqdn      = var.target_fqdn
    target_origin_ip = var.target_origin_ip
    tool_tier        = var.tool_tier
  }))

  tags = azurerm_resource_group.main.tags
}

Cloud-Init 佈建

cloud-init.yaml 是經過生產環境驗證的設定，已通過超過 48 小時的持續負載測試，包含 4 輪來源壓力測試。它使用具備重試邏輯的輔助程式庫、將進度記錄至 /var/log/cloud-init-progress.log、9 個佈建階段，以及條件式狀態回報（status.json 中的 ready/degraded）。其佈建內容包括：

核心調校 — somaxconn=131072、tcp_max_tw_buckets=4000000、tcp_fin_timeout=5、64 MiB 通訊端緩衝區、file-max=4194304
NIC 最佳化 — 跨所有核心的 RPS/RFS、透過 ethtool 最大化環形緩衝區、THP=always
APT 套件 — nikto、nmap、masscan、sqlmap、hydra、medusa、ncrack、tshark、hping3、tcpdump、netcat、ngrep、iperf3、mtr、sslscan、socat、dirb、whatweb、wrk、hey、vegeta、ethtool
GitHub Releases — nuclei、dalfox、ffuf、gobuster、feroxbuster、subfinder、httpx、amass
Python 套件 — mitmproxy、sslyze、dnsrecon、fierce、theHarvester、playwright、scapy、impacket、arjun
Node.js 20.x — 搭載隱身外掛的 Puppeteer，用於機器人模擬
瀏覽器自動化 — 用於無頭瀏覽器測試的 Playwright Chromium
Git 複製 — testssl.sh、recon-ng、spiderfoot、SecLists、waf-bypass、PayloadsAllTheThings
套件部署 — 從此儲存庫複製 19 個流量套件至 /opt/traffic-generator/suites/
設定檔 — 包含 TARGET_FQDN、TARGET_ORIGIN_IP 及 CRAPI_PORT 的 config.env

cloud-init 使用 Terraform 範本變數：${target_fqdn}、${target_origin_ip} 及 ${tool_tier}。Shell 變數（如 $NPROC）在 Terraform templatefile 中以 $$NPROC 形式轉義。

範例變數檔案

將 terraform.tfvars.example 複製為 terraform.tfvars 並填入您的值。.gitignore 已排除 terraform.tfvars 以防止提交憑證：

# Copy this file to terraform.tfvars and fill in your values.
# terraform.tfvars is gitignored — never commit real credentials.

# --- Required ---
subscription_id = "00000000-0000-0000-0000-000000000000"
target_fqdn     = "demo.example.com"

# --- Optional overrides (defaults shown) ---
# deployer            = ""                       # auto-resolved from Azure AD
# location            = "eastus2"

# tags                = {}
# target_origin_ip    = ""
# tool_tier           = "standard"

將 subscription_id 替換為您的 Azure 訂閱 ID（從 az account show --query id -o tsv 取得），並將 target_fqdn 替換為您的 F5 XC 負載平衡器網域。

部署

terraform init

terraform plan

terraform apply

成功部署後，Terraform 會輸出公用 IP、SSH 命令及目標 FQDN。

VM 規格調整

建議針對此 CPU 密集型流量產生工作負載使用 F 系列計算最佳化 VM。Cloud-init 核心調校及工具並行數會隨 vCPU 數量自動擴充。

VM SKU	vCPU	RAM	網路	使用情境
Standard_F4s_v2	4	8 GiB	10 Gbps	輕量實驗室/示範
Standard_F8s_v2	8	16 GiB	12.5 Gbps	標準示範
Standard_F16s_v2	16	32 GiB	12.5 Gbps	負載測試（預設）
Standard_F32s_v2	32	64 GiB	16 Gbps	大量基準測試
Standard_D16s_v3	16	64 GiB	12.5 Gbps	記憶體密集工作負載

部署後驗證

Cloud-init 佈建標準層需要 15-20 分鐘，完整層約需 25 分鐘。VM 可透過 SSH 立即存取，但在 cloud-init 完成之前，工具仍在持續安裝中。

等待 Cloud-Init

透過 SSH 連線至 VM 並等待佈建完成：

ssh azureuser@$(terraform output -raw public_ip)

cloud-init status --wait

完成後的預期輸出：

status: done

檢查狀態檔案

cloud-init 腳本完成後會寫入狀態檔案：

cat /opt/traffic-generator/status.json

預期輸出：

{
  "status": "ready",
  "tier": "standard",
  "target_fqdn": "demo.example.com",
  "completed": "2026-04-25T14:30:00Z",
  "tools_installed": true
}

驗證關鍵工具

執行驗證迴圈以確認每個關鍵工具均可在 PATH 中使用：

for tool in nikto sqlmap nuclei dalfox ffuf gobuster feroxbuster nmap masscan \
  hydra medusa ncrack sslscan tshark hping3 mitmproxy sslyze subfinder httpx \
  amass arjun mtr whatweb dirb socat netcat ngrep iperf3 whois dig wrk hey; do
  if command -v "$tool" > /dev/null 2>&1; then
    echo "OK: $tool"
  else
    echo "MISSING: $tool"
  fi
done

驗證套件執行器

確認執行器與套件已安裝：

ls /opt/traffic-generator/suites/runner.sh
ls /opt/traffic-generator/suites/*/

/opt/traffic-generator/suites/runner.sh web-app-attacks --dry-run

擷取任何輸出：

terraform output -raw ssh_command

從上游元件串接

流量產生器以位於來源伺服器前端的 F5 XC HTTP 負載平衡器為目標。請先部署來源伺服器、設定 F5 XC，然後將 target_fqdn 設定為負載平衡器的 FQDN：

# After deploying origin-server and creating an F5 XC HTTP load balancer:
cat > terraform.tfvars <<EOF
subscription_id  = "your-subscription-id"
target_fqdn      = "your-xc-load-balancer.example.com"
target_origin_ip = "$(cd ../../origin-server/terraform && terraform output -raw public_ip)"
EOF

必填變數	來源	說明
`target_fqdn`	F5 XC 主控台	保護來源伺服器的 HTTP 負載平衡器 FQDN
`target_origin_ip`	來源伺服器 `public_ip` 輸出	用於繞過測試的直接來源 IP（選填）

請前往工具目錄查閱完整工具參考，或前往套件開始產生流量。
