This blog series chronicles my experience deploying and learning the technical details of the AKS Demo Store App with Azure Open AI. The app uses AI to generate product descriptions, deployed in a Kubernetes architecture. It showcases Azure Open AI's potential and the future application focus.
The following is a walk through of a quick setup of Azure Managed Grafana Instance and viewing performance graphs on applications running in Azure Kubernetes Service. This is a relatively new Azure platform service and the general documentation can be found at https://learn.microsoft.com/en-us/azure/managed-grafana/how-to-data-source-plugins-managed-identity?tabs=azure-portal I have had experience to build, configure and deploy Grafana into an …
Implementation scenario to establish autorotation of pod mounted key vault secrets and reloading pods to update environment variables of those secrets.
Scenario: You require a pod to mount a secret stored in an Azure Key Vault. So that an application running in the pod can access the secret as a file and environment variable. Also manage the access security between the AKS cluster to the key vault using a user assigned managed identity. Background: To integrate …

My Blog Post: An ASP .NET Core app hosted in Azure Kubernetes Service (AKS) that is accessing an Azure SQL Database using Azure AD Managed Identity. The benefit is the ability for the application code not to use conventional SQL credentials of username and password stored in configuration files. Also, not use Azure Key vault to retrieve any user name and password credentials. There is nothing wrong with these techniques, but using Managed Identity is more streamlined and is a security best practice. #AKS #Kubernetes #Security #managedidentity #azureAD #AzureSQL
One of the non-straight forward aspects of implementing for applications in Kubernetes is the stateful data store. I will be showing 2 relational database patterns in Azure Kubernetes Service. Since containers are the fundamental building blocks, these are stateless by default. That is the containers can lose its data when it is terminated or fail. …
