KubeConNA | Building Carbon Awareness with KEDA: Taking the First Step Towards Sustainability

2023-11-16 1 min read Speaking

Speaking at KubeConNA 2023 was an awesome experience. But what was equally awesome was being able to speak about a topic and project that was very close to my heart. I spoke about how we can build carbon awareness on the Kubernetes platform with the open-source KEDA project, and how we can take the first step towards sustainability just by being aware of the carbon intensity of energy produced during time periods and reducing our demand for energy during those periods.

Bootstrap your GitOps-enabled AKS cluster with Terraform: A code sample using the Flux v2 K8s Extension

2023-09-28 6 min read GitOps Kubernetes Developer Tutorial

In my previous posts, we learned how to get started with GitOps on AKS using the K8s extension for AKS. Then, we took a look at the Flux CLI and explored how it can be used to bootstrap your cluster and generate FluxCD manifests so that we can use GitOps to implement GitOps 🤯, and implemented Flux’s image update automation capability. From there, we built on the concept of image update automation, and showed you how you can use Flagger to automate canary deployments. Continue reading

Progressive Delivery on AKS: A Step-by-Step Guide using Flagger with Istio and FluxCD

2023-09-26 13 min read GitOps Kubernetes Developer Tutorial

In my previous post, we setup an Azure Kubernetes Service (AKS) cluster to automatically update images based on new image tags in a container registry. As soon as a new image was pushed to the registry the image was immediately updated. But what if you don’t want an agent automatically pushing out new images without some sort of testing? 🤔 In this article, we’ll build upon Flux’s image update automation capability and add Flagger to implement a canary release strategy. Continue reading

Automating Image Updates with FluxCD on AKS

2023-09-22 13 min read GitOps Kubernetes Developer Tutorial

In my previous post, we walked through the setup of FluxCD on AKS via AKS extensions. In this article, we’ll go a bit deeper and take a look at how you can use FluxCD to automate image updates in your AKS cluster. The goal here is to streamline the process of updating your application deployments in your cluster. Here is our intended workflow: Modify application code, then commit and push the change to the repo. Continue reading
