Quickstart: Set and retrieve a secret from Azure Key Vault using Azure CLI

Azure Key Vault is a cloud service that works as a secure secrets store. You can securely store keys, passwords, certificates and other secrets. For more information on Key Vault you may review the Overview. Azure CLI is used to create and manage Azure resources using commands or scripts. In this quickstart, you create a key vault. Once that you have completed that, you will store a secret.

If you don't have an Azure subscription, create a free account before you begin.

Open Azure Cloud Shell

Azure Cloud Shell is a free, interactive shell that you can use to run the steps in this article. Common Azure tools are preinstalled and configured in Cloud Shell for you to use with your account. Just select the Copy button to copy the code, paste it in Cloud Shell, and then press Enter to run it. There are a few ways to open Cloud Shell:

Select Try It in the upper-right corner of a code block. Cloud Shell in this article
Open Cloud Shell in your browser. https://shell.azure.com/bash
Select the Cloud Shell button on the menu in the upper-right corner of the Azure portal. Cloud Shell in the portal

If you choose to install and use the CLI locally, this quickstart requires the Azure CLI version 2.0.4 or later. Run az --version to find the version. If you need to install or upgrade, see Install the Azure CLI.

To log in to the Azure using the CLI you can type:

az login

Create a resource group

A resource group is a logical container into which Azure resources are deployed and managed. The following example creates a resource group named ContosoResourceGroup in the eastus location.

az group create --name 'ContosoResourceGroup' --location eastus

Create a Key Vault

Next you will create a Key Vault in the resource group created in the previous step. You will need to provide some information:

  • For this quickstart we use Contoso-vault2. You must provide a unique name in your testing.
  • Resource group name ContosoResourceGroup.
  • The location East US.
az keyvault create --name 'Contoso-Vault2' --resource-group 'ContosoResourceGroup' --location eastus

The output of this cmdlet shows properties of the newly created Key Vault. Take note of the two properties listed below:

  • Vault Name: In the example, this is Contoso-Vault2. You will use this name for other Key Vault commands.
  • Vault URI: In the example, this is https://contoso-vault2.vault.azure.net/. Applications that use your vault through its REST API must use this URI.

At this point, your Azure account is the only one authorized to perform any operations on this new vault.

Add a secret to Key Vault

To add a secret to the vault, you just need to take a couple of additional steps. This password could be used by an application. The password will be called ExamplePassword and will store the value of Pa$$w0rd in it.

Type the commands below to create a secret in Key Vault called ExamplePassword that will store the value Pa$$w0rd :

az keyvault secret set --vault-name 'Contoso-Vault2' --name 'ExamplePassword' --value 'Pa$$w0rd'

You can now reference this password that you added to Azure Key Vault by using its URI. Use https://ContosoVault.vault.azure.net/secrets/ExamplePassword to get the current version.

To view the value contained in the secret as plain text:

az keyvault secret show --name 'ExamplePassword' --vault-name 'Contoso-Vault2'

Now, you have created a Key Vault, stored a secret, and retrieved it.

Clean up resources

Other quickstarts and tutorials in this collection build upon this quickstart. If you plan to continue on to work with subsequent quickstarts and tutorials, you may wish to leave these resources in place. When no longer needed, you can use the az group delete command to remove the resource group, and all related resources. You can delete the resources as follows:

az group delete --name ContosoResourceGroup

Next steps

In this quickstart, you have created a Key Vault and stored a secret in it. To learn more about Key Vault and how you can use it with your applications continue to the tutorial for web applications working with Key Vault.
