Reading Time: 4 minutesEvery so often, Microsoft quietly updates an existing docs page and sneaks in a feature that solves a problem you didn’t even realise was fixable. The MaxUnavailable fallback is one of those. I picked it up through the AKS Docs Tracker I run here on pixelrobots.co.uk, which flagged a change Read more
Reading Time: 8 minutesMicrosoft recently released a public preview of cert-manager as an Azure Arc Kubernetes extension. The docs focus entirely on Arc-enabled clusters, which makes sense given it shipped under the Arc umbrella. But I wanted to know whether it would work on a regular AKS cluster, and the short answer is Read more
Reading Time: 7 minutesI spotted this in the AKS release notes recently and it is worth paying attention to if you are running multi-zone clusters. Microsoft has added managedNATGatewayV2 as a new outbound type for AKS, and the key difference from the existing managedNATGateway is zone redundancy. The original option is tied to Read more
Reading Time: 10 minutesI spotted this one via the AKS Docs Tracker I built and run here on pixelrobots.co.uk. It picked up new docs appearing under the AKS section and this one caught my eye immediately. Microsoft has shipped a public preview of something called Container Network Insight Agent, and it is genuinely Read more
Reading Time: 4 minutesI picked this up from my AKS Docs Tracker when the docs page for Cluster Health Monitor appeared. It is currently in preview, but it is one of the more operationally interesting things Microsoft has quietly added to AKS in a while. This is not a dashboard feature. It is Read more
Reading Time: 8 minutesI have been waiting for something like this for a while. If you run AKS at any meaningful scale, one of the hardest problems you eventually hit is the multi-cluster networking story. How do services across clusters discover each other? How do you enforce mTLS across cluster boundaries? How do Read more
Reading Time: 5 minutesI spotted something land in the Azure CLI extensions repo this week. PR #9669 adds CLI support for App Routing Istio, including new –enable-app-routing-istio flags on az aks create and az aks update, plus dedicated az aks approuting gateway istio enable and disable subcommands in the aks-preview extension. The PR Read more
Reading Time: 5 minutesI’ve been running AKS clusters in production for a long time. I’ve seen the same patterns play out over and over, someone stands up a cluster, it works great in dev, and then six months later they’re rebuilding the whole thing because a networking decision made on day one turned Read more
Reading Time: 8 minutesAfter writing about Ingress NGINX retiring in March 2026, I recommended a two-phase migration approach. Start with Application Routing add-on for quick stability, then migrate to Envoy Gateway as the long-term strategic choice. Several readers asked for more detail on the Envoy Gateway piece, specifically around installation and the different configuration Read more
Reading Time: 4 minutesWe’ve all been there. You upgrade a node pool, something breaks in production, and you’re left deciding whether to push forward with a fix or try to undo what you just did. Until recently, “undoing” a Kubernetes version upgrade in AKS wasn’t a first-class operation. You’d be looking at manual Read more
