Learn how to use Prometheus Adapter to horizontally scale services in Kubernetes automatically based on Prometheus metrics. — The Horizontal Pod Autoscaler (HPA) is a fundamental feature of Kubernetes. It enables automatic scale-up and scale-down of containerized applications based on CPU usage, memory usage, or custom metrics. Traditionally, when scaling software, we first think of vertical scaling: the CPU and the RAM are increased so the application consuming…

Learn how to use Metrics Server to horizontally scale native and JVM services in Kubernetes automatically based on resource metrics. — The Horizontal Pod Autoscaler (HPA) is a fundamental feature of Kubernetes. It enables automatic scale-up and scale-down of containerized applications based on CPU usage, memory usage, or custom metrics. Traditionally, when scaling software, we first think of vertical scaling: the CPU and the RAM are increased so the application consuming…

Learn how to conduct a mobile force update incrementally with a simple canary deployment using Ingress NGINX and Firebase Remote Config. — Mobile force updates occur when old versions of an app are no longer compatible with the APIs they consume. Until the app is updated to the required version, the UI blocks further usage. This is usually materialized as a system popup that will redirect users to the respective Store and…

Learn how to use Argo Rollouts with Prometheus to automate the detection and rollback of faulty deployments using AnalysisTemplates. — Deploying to production in Kubernetes can be quite stressful. Even after meaningful and reliable automated tests have successfully passed, there is still room for things to go wrong and lead to a nasty incident when pressing the final button. Thankfully, Kubernetes is made to be resilient to this kind of…

Learn how to use Argo Rollouts to improve a Canary Deployment setup using Ingress NGINX and automate incremental rollouts. — Deploying to production in Kubernetes can be quite stressful. Even after meaningful and reliable automated tests have successfully passed, there is still room for things to go wrong and lead to a nasty incident when pressing the final button. Thankfully, Kubernetes is made to be resilient to this kind of…

Learn how to use Ingress NGINX to set up a Canary Deployment allowing isolated Smoke Testing and incremental rollout to minimize risk. — Deploying to production in Kubernetes can be quite stressful. Even after meaningful and reliable automated tests have successfully passed, there is still room for things to go wrong and lead to a nasty incident when pressing the final button. Thankfully, Kubernetes is made to be resilient to this kind of…
