Setting Up Azure Workload Identity for Containers in Azure Kubernetes Services (AKS) Using Terraform - Improved Security for Containers in AKS

 Azure Workload Identity allows your containers in AKS touse amanaged identity to access Azure resources securely without having to depend on connection strings, passwords, access keys or secrets. In other works you can just use DefaultAzureCredential in your containers running in AKS, which will be using workload identity assigned to the container, to get access to the required Azure resource. The roale based access permissions will be in effect and the user assigned managed identity (we can use AD app registration as well bu user assigned managed identity is recommended) used to setup the workload identity in AKS should be given the necessary roles in the target Azure resource. This is far better than having to store secrets or connection stigs to utilized by the dotnet applications. In this post let's understand how to setup workload identity in AKS deployed containers and explore how it simplifies the dotnet application code allowing the application to access Azure resources securely with a managed identity.

Full example source code with terraform and a .NET application using default credentials to access app config service and keyvault is available here in my GitHub repo,
