For all the criticism of ...In Kubernetes, a Service is a method for exposing a network application that is running as one or more Pods in your cluster. A key aim of Services in Kubernetes is that you don't need to modify your existing application to use an unfamiliar service discovery mechanism. You can run code in Pods, whether this is a code designed for a cloud-native ... The main purpose of HPA is to automatically scale your deployments based on the load to match the demand. Horizontal, in this case, means that we're talking about scaling the number of pods. You can specify the minimum and the maximum number of pods per deployment and a condition such as CPU or memory usage. Kubernetes will constantly monitor ... HPA increases or decreases the pod count, whereas VPA automatically increases or decreases the CPU and memory reservations of the pods to help you “right-size” your applications. HPA and VPA achieve Kubernetes Autoscaling at pod level. You need the Kubernetes Autoscaler to increase the number of nodes in the cluster.prometheus-adapter queries Prometheus, executes the seriesQuery, computes the metricsQuery and creates "kafka_lag_metric_sm0ke". It registers an endpoint with the api server for external metrics. The API Server will periodically update its stats based on that endpoint.

Make sure you are not seeing anything unusual about the metrics server installation: # This should show you metrics (they come from the metrics server) $ kubectl top pods. $ kubectl top nodes. or check the logs: $ kubectl logs <metrics-server-pod>. Kubernetes HPA vs. VPA. Kubernetes HPA (Horizontal Pod Autoscaler) and VPA (Vertical Pod Autoscaler) are both tools used to automatically adjust the resources allocated to pods in a Kubernetes cluster.
