How to Create Key Vault in Azure: Step-by-Step Guide

To create a Key Vault in Azure, use the Azure CLI command az keyvault create with your resource group and vault name. This sets up a secure place to store keys, secrets, and certificates.

Syntax

The basic syntax to create an Azure Key Vault using Azure CLI is:

• az keyvault create: Command to create the vault.
• --name: The unique name for your Key Vault.
• --resource-group: The resource group where the vault will be created.
• --location: The Azure region for the vault.

bash

az keyvault create --name <vault-name> --resource-group <resource-group-name> --location <location>

Example

This example creates a Key Vault named myKeyVault123 in the resource group myResourceGroup located in eastus. It shows how to run the command and the expected output.

bash

az keyvault create --name myKeyVault123 --resource-group myResourceGroup --location eastus

Output

{
  "id": "/subscriptions/xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx/resourceGroups/myResourceGroup/providers/Microsoft.KeyVault/vaults/myKeyVault123",
  "location": "eastus",
  "name": "myKeyVault123",
  "properties": {
    "sku": {
      "family": "A",
      "name": "standard"
    },
    "tenantId": "xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx",
    "vaultUri": "https://myKeyVault123.vault.azure.net/"
  },
  "resourceGroup": "myResourceGroup",
  "type": "Microsoft.KeyVault/vaults"
}

Common Pitfalls

Common mistakes when creating a Key Vault include:

• Using a vault name that is not globally unique, which causes errors.
• Not specifying the correct resource group or location.
• Missing Azure CLI login or subscription context before running the command.

Always ensure you are logged in with az login and have selected the right subscription with az account set.

bash

## Wrong: Missing resource group
az keyvault create --name myKeyVault123 --location eastus

## Right: Include resource group
az keyvault create --name myKeyVault123 --resource-group myResourceGroup --location eastus

Quick Reference

Remember these tips when creating your Azure Key Vault:

• Vault name must be unique across Azure.
• Choose the closest region to your app for better performance.
• Use resource groups to organize your resources.
• Login and set subscription before creating the vault.
