The metrics will be exposed at /apis/metrics.k8s.io as we saw in the previous section and will be used by HPA. Most non-trivial applications need more metrics than just memory and CPU and that is why most organization use a monitoring tool. Some of the most commonly used monitoring tools are Prometheus, Datadog, Sysdig etc.HPA uses the custom.metrics.k8s.io API to consume these metrics. This API is enabled by deploying a custom metrics adapter for the metrics collection solution. For this example, we are going to use Prometheus.

I've added hpa description to the question. Flapping of replicas happens not always, hard to catch a state before scaling. Don't see terminating pods and no errors in logs, so I believe it is because autoscaling. Had no pods restarts before HPA enabled. I didn't try newer version of K8s, version might be a reason. –One that collects metrics from our applications and stores them to Prometheus time series database.

This is an implementation of the custom metrics API that attempts to support arbitrary metrics.

There are three types of K8s autoscalers, each serving a different purpose. They are: Horizontal Pod Autoscaler (HPA): adjusts the number of replicas of an application. HPA scales the number of pods in a replication controller, deployment, replica set, or stateful set based on CPU utilization. The Horizontal Pod Autoscaler (HPA) automatically scales the number of replicas of an application; in other words the number of Pods in a replication controller, deployment, replica set or stateful set, based on observed values of a metric.

You can use kubectl get pods again to see the unneeded pods being removed.

May 16, 2020 · Scaling based on custom or external metrics requires deploying a service that implements the custom.metrics.k8s.io or external.metrics.k8s.io API to provide an interface with the monitoring service or alternate metrics source. For workloads using the standard CPU metric, containers must have CPU resource limits configured in the pod spec. 2.

Custom metrics are user-defined performance indicators that extend the default resource metrics (e.g., CPU and memory) supported by the Horizontal Pod Autoscaler (HPA) in Kubernetes. By default, HPA bases its scaling decisions on pod resource requests, which represent the minimum resources required …If you are running on maximum, you might want to check if the given maximum is to low.
