AKS with Workload Identity

Summary: Workloads deployed on an Azure Kubernetes Services (AKS) cluster require Microsoft Entra application credentials or managed identities to access Microsoft Entra protected resources, such as a Azure Key Vault. Microsoft Entra Workload ID integrates with the capabilities native to Kubernetes to federate with external identity providers. On this page I'll show you how to quickly deploy an AKS cluster with workload identity enabled.
Date: 26 January 2025

I'll show you the following steps:

Deploy an AKS cluster using the Azure CLI with the OpenID Connect issuer and a Microsoft Entra Workload ID.
Create a Microsoft Entra Workload ID and Kubernetes service account.
Configure the managed identity for token federation.
Deploy a test workload and verify authentication with the workload identity.
Grant a pod in the cluster access to secrets in an Azure key vault.

All command shown here are done with powershell in the Azure Cloud Shell.

JavaScript Referrer

Summary: How to create a referrer (redirect) using javascript
Date: Around 2018
Refactor: 1 March 2025: Checked links and formatting.

Use this javascript to set a referrer, meaning that if a user visits a page directly it gets referred to the main page. This way you enforce users to always use the mainpage:

<script type="text/javascript">
if (document.referrer !== "http://mainpage.url.com/") {
    window.location.href = "http://mainpage.url.com/";
}
</script>
