Git going with GitOps on AKS: A Step-by-Step Guide using FluxCD AKS Extension

2023-09-20 12 min read GitOps Kubernetes Developer Tutorial

In reading through @StevenMurawski’s blog post titled, What Really is GitOps? we learned that GitOps is a way to do Continuous Delivery of our applications on Kubernetes. In this post, I will jump right into how you can “git” going with GitOps by enabling the FluxCD AKS Extension on your Azure Kubernetes Service (AKS) and using a tool called Kustomize to help with Kubernetes configuration management. We’ll deploy my new favorite demo app, AKS Store Demo to our AKS cluster and then make some changes to the application and see how FluxCD handles them. Continue reading

Deploying ARM64 workloads to AKS

2022-11-02 6 min read Tutorial

You might have heard by now that Azure has partnered with Ampere to bring ARM-based processors for virtual machines on Azure. This is super exciting as it gives you an opportunity to deploy workloads on highly performant and power efficient virtual machines and these characteristics ultimately result in excellent price-performance (lower costs 🥳) So… are you ready to deploy your workloads to ARM64 node pools on AKS? I sure wasn’t when attempting to deploy the azure-voting-app-redis application to my cluster. Continue reading
