Azure Key Vault Connection

Learn how to configure a Azure Key Vault Connection for Infisical.

Infisical currently only supports two methods for connecting to Azure, which are OAuth and Client Secrets.

Self-Hosted Instance

Using the Azure Key Vault connection on a self-hosted instance of Infisical requires configuring an application in Azure and registering your instance with it.

Prerequisites:

• Set up Azure and have an existing Key Vault instance.

1. Create an application in Azure

   Navigate to Azure Active Directory > App registrations to create a new application.

   Azure Active Directory is now Microsoft Entra ID.

   

   Create the application. As part of the form, set the Redirect URI to https://your-domain.com/organization/app-connections/azure/oauth/callback.

   The domain you defined in the Redirect URI should be equivalent to the SITE_URL configured in your Infisical instance.

   

2. Assign API permissions to the application

   For the Azure Connection to work with Key Vault, you need to assign multiple permissions to the application.

   Azure Key Vault permissions

   Set the API permissions of the Azure application to include user.impersonation for the Key Vault API.

3. Add your application credentials to Infisical

   Obtain the Application (Client) ID in Overview and generate a Client Secret in Certificate & secrets for your Azure application.

   

   Back in your Infisical instance, add two new environment variables for the credentials of your Azure application.

   • INF_APP_CONNECTION_AZURE_KEY_VAULT_CLIENT_ID: The Application (Client) ID of your Azure application.
   • INF_APP_CONNECTION_AZURE_KEY_VAULT_CLIENT_SECRET: The Client Secret of your Azure application.

   Once added, restart your Infisical instance and use the Azure Key Vault connection.

Client Secret Authentication

To use client secret authentication, ensure your Azure Service Principal has the required permissions and is connected to the Azure Key Vault instances you want to use.

Prerequisites:

• Set up Azure and have an existing Key Vault instance.
• The service principal must be connected to your target Azure Key Vault instance(s)

1. Assign API permissions to the service principal

   Configure the required API permissions for your App Registration to interact with Azure Key Vault:

   Azure Key Vault permissions

   Set the API permissions of your Azure service principal to include user_impersonation for the Key Vault API.
