Daniel Neumann, writing on Daniel's Tech Blog described a recent experience updating a Terraform AKS module, switching from Azure Active Directory service principal to managed identity while simultaneously switching from AD v1 to v2, which is managed. terraform providers- azurerm - azuread - local - tls Definition of providers in terraform is shown below.

In this blog post, I will explain how you can use the aad-pod-identity project (currently in Beta) to get an Azure managed identity bound to a pod running in your Kubernetes cluster. The resource only requires one parameter. With managed identities, Azure takes care of all those tasks for us. The text was updated successfully, but these errors were encountered: at GA the SA managed identity will be created by default, no explicit flag will be required. Earlier in the guide we setup a data source to read the available AKS versions in our region. I’m going to assume enough proficiency in Terraform that you’re able to declare and fill out these variables on your own. A managed identity is a wrapper around a Service Principal.

First, create an Azure resource group: # Create an Azure resource group az group create --name myResourceGroup --location westus2 Then, create an AKS cluster: az aks create -g myResourceGroup -n myManagedCluster --enable-managed-identity Recently, I updated my Terraform AKS module switching from the AAD service principal to managed identity option as well from the AAD v1 integration to AAD v2 which is also managed. Really helpful . The resource to create an empty group is simple and requires one property. Beside that when you enable the add-ons Azure Monitor for containers and Azure Policy for AKS, each add-on gets its own managed identity. The result of the above command is a User Assigned Managed Identity called rgapi. tenant_id - The Tenant ID for the Service Principal associated with the Managed Service Identity. For example, in order to deploy this AKS cluster in the “aks-subnet” subnet, Terraform knows it has to create the vnet and subnet first.

Thanks! In this demo your Azure account will be accessed by Terraform using a Service Principal. It's just any Terraform resources that are kubernetes specific like 'kubernetes_persistent_volume" or "kubernetes_role" that … The cluster control plane is deployed and managed by Microsoft while the node and node pools where the applications are deployed, are handled by the customer.
