How Do I Build an Azure Keyvault Key With Pulumi?

Introduction

In this guide, we will demonstrate how to create an Azure Key Vault and a Key Vault Key using Pulumi in TypeScript. Azure Key Vault is a cloud service that provides a secure store for secrets, keys, and certificates. It helps safeguard cryptographic keys and secrets used by cloud applications and services. Pulumi is an Infrastructure as Code (IaC) tool that allows you to define and manage cloud resources using familiar programming languages.

Step-by-Step Explanation

Step 1: Set Up Pulumi Project

First, ensure that you have Pulumi CLI installed. Create a new Pulumi project by running the following commands:

mkdir pulumi-azure-keyvault
cd pulumi-azure-keyvault
pulumi new azure-typescript

This will create a new Pulumi project with the necessary configuration files.

Step 2: Install Azure Native Package

Install the Pulumi Azure Native package to interact with Azure resources:

npm install @pulumi/azure-native

Step 3: Import Required Modules

In your index.ts file, import the necessary modules:

import * as pulumi from "@pulumi/pulumi";
import * as azure from "@pulumi/azure-native";

Step 4: Create Resource Group

Create an Azure Resource Group to hold the Key Vault:

const resourceGroup = new azure.resources.ResourceGroup("resourceGroup", {
    resourceGroupName: "my-resource-group",
    location: "WestUS",
});

Step 5: Create Key Vault

Create an Azure Key Vault within the Resource Group:

const keyVault = new azure.keyvault.Vault("keyVault", {
    resourceGroupName: resourceGroup.name,
    location: resourceGroup.location,
    properties: {
        sku: { family: "A", name: "standard" },
        tenantId: azure.config.tenantId,
        accessPolicies: [],
    },
});

Step 6: Create Key Vault Key

Create a Key Vault Key within the Key Vault:

const key = new azure.keyvault.Key("key", {
    resourceGroupName: resourceGroup.name,
    vaultName: keyVault.name,
    properties: {
        kty: "RSA",
        keySize: 2048,
    },
});

Step 7: Export Key Vault and Key Details

Export the Key Vault and Key details to view them after deployment:

export const keyVaultName = keyVault.name;
export const keyName = key.name;

Key Points

• Azure Key Vault: A secure store for secrets, keys, and certificates.
• Pulumi: An IaC tool that allows you to define and manage cloud resources using programming languages.
• Resource Group: A container that holds related resources for an Azure solution.
• Key Vault Key: A cryptographic key stored in Azure Key Vault.

Conclusion

In this guide, we have demonstrated how to create an Azure Key Vault and a Key Vault Key using Pulumi in TypeScript. By following the steps outlined above, you can securely manage your cryptographic keys and secrets in Azure. Pulumi makes it easy to define and manage cloud resources using familiar programming languages, streamlining the process of infrastructure management.

Full Code Example

import * as pulumi from "@pulumi/pulumi";
import * as azure from "@pulumi/azure-native";

// Create an Azure Resource Group
const resourceGroup = new azure.resources.ResourceGroup("resourceGroup", {
    resourceGroupName: "my-resource-group",
    location: "WestUS",
});

// Create an Azure Key Vault
const keyVault = new azure.keyvault.Vault("keyVault", {
    resourceGroupName: resourceGroup.name,
    location: resourceGroup.location,
    properties: {
        sku: { family: "A", name: "standard" },
        tenantId: pulumi.output(azure.config.tenantId).apply(tid => tid || ""),
        accessPolicies: [],
    },
});

// Create a Key Vault Key
const key = new azure.keyvault.Key("key", {
    resourceGroupName: resourceGroup.name,
    vaultName: keyVault.name,
    properties: {
        kty: "RSA",
        keySize: 2048,
    },
});

// Export the Key Vault and Key details
export const keyVaultName = keyVault.name;
export const keyName = key.name;
