terraform-azurerm-diskencrypt

Encrypt an existing Virtual Machine in Azure

This module implements Azure Disk Encryption feature to encrypt currently running VM's. ADE leverages the industry standard BitLocker feature of Windows and DM-Crypt feature of linux to provide volume encryption for the OS and data disks.

prerequisites

All the prerequsites can be found at the Azure Disk Encryption prerequisites

Setting the Advanced access policies for the Key Vault is required for this module to work.

** Important Note We need to enable disk backup to encrypt managed data disks. **

Usage

module "diskencrypt" {
  source               = "Azure/diskencrypt/azurerm"
  resource_group_name  = "myapp"
  location             = "westus"
  vm_name              = "ubuntu1"
  key_vault_name       = "testkeyvault123"
  encryption_algorithm = "RSA-OAEP"
  encryption_key_url   = "https://testkeyVault123.vault.azure.net:443/keys/ContosoFirstKey/9465333262aa49468c7f0dad5a167ee8"
  
  tags = {
    environment = "dev"
    costcenter  = "it"
  }
}

Test

Configurations

• Configure Terraform for Azure

We provide 2 ways to build, run, and test the module on a local development machine. Native (Mac/Linux) or Docker.

Native (Mac/Linux)

Prerequisites

• Ruby (~> 2.3)
• Bundler (~> 1.15)
• Terraform (~> 0.11.7)
• Golang (~> 1.10.3)

Environment setup

We provide simple script to quickly set up module development environment:

$ curl -sSL https://raw.githubusercontent.com/Azure/terramodtest/master/tool/env_setup.sh | sudo bash

Run test

Then simply run it in local shell:

$ cd $GOPATH/src/{directory_name}/
$ bundle install
$ rake build
$ rake e2e

Docker

We provide a Dockerfile to build a new image based FROM the microsoft/terraform-test Docker hub image which adds additional tools / packages specific for this module (see Custom Image section). Alternatively use only the microsoft/terraform-test Docker hub image by using these instructions.

Prerequisites

• Docker

Custom Image

This builds the custom image:

$ docker build --build-arg BUILD_ARM_SUBSCRIPTION_ID=$ARM_SUBSCRIPTION_ID --build-arg BUILD_ARM_CLIENT_ID=$ARM_CLIENT_ID --build-arg BUILD_ARM_CLIENT_SECRET=$ARM_CLIENT_SECRET --build-arg BUILD_ARM_TENANT_ID=$ARM_TENANT_ID -t azure-diskencrypt .

This runs the build and unit tests:

$ docker run --rm azure-diskencrypt /bin/bash -c "bundle install && rake build"

This runs the end to end tests:

$ docker run --rm azure-diskencrypt /bin/bash -c "bundle install && rake e2e"

This runs the full tests:

$ docker run --rm azure-diskencrypt /bin/bash -c "bundle install && rake full"
