terraform-azurerm-panos-bootstrap

Creates a PAN-OS bootstrap package in Microsoft Azure.

terraform-azurerm-panos-bootstrap

The terraform-azurerm-panos-bootstrap module is used to create an Azure file share that to be used for bootstrapping Palo Alto Networks VM-Series virtual firewall instances. A bootstrap package must include an init-cfg.txt file that provides the basic configuration details to configure the VM-Series instance and register it with its Panorama management console. This file will be generated by this module using the variables provided.

The bootstrap package may optionally include a PAN-OS software image, application and threat signature updates, VM-Series plug-ins, and/or license files.

Directory and file structure

The root directory of the Terraform plan calling this module should include a files directory containing a subdirectory structure similar to the one below.

files
├── config
├── content
├── license
├── plugins
└── software

Example

#
# main.tf
#

provider "azurerm" {
  subscription_id = var.azure_subscription_id
  tenant_id       = var.azure_tenant_id
  client_id       = var.azure_client_id
  client_secret   = var.azure_client_secret
}


module "panos-bootstrap" {
  source  = "PaloAltoNetworks/panos-bootstrap/azurerm"
  version = "1.0.4"

  azure_resource_group = var.azure_resource_group
  azure_location       = var.azure_location

  hostname         = "my-firewall"
  panorama-server  = "panorama1.example.org"
  panorama-server2 = "panorama2.example.org"
  tplname          = "My Firewall Template"
  dgname           = "My Firewalls"
  vm-auth-key      = "supersecretauthkey"
}

Requirements

The Azure CLI must be installed on the host executing the Terraform plan.

Instructions

Define a main.tf file that calls the module and provides any required and optional variables.
Define a variables.tf file that declares the variables that will be utilized.
(OPTIONAL) Define an output.tf file to capture and display the module return values.
Create the directories files/config, files/software, files/content, files/license, and files/plugins.
(OPTIONAL) Add software images, content updates, plugins, and license files to their respective subdirectories.
(OPTIONAL) Define a terraform.tfvars file containing the required variables and associated values.
Initialize the providers and modules with the terraform init command.
Validate the plan using the terraform plan command.
Apply the plan using the terraform apply command.

Utilization

The module output will provide values for the storage_account, access_key, and share_name. These values can then be used in a azurerm_virtual_machine resource to instantiate a VM-Series instance. They are used in the os_profile{custom_data} parameter.
