Jul 2, 2019 · Amazon CloudWatch Metrics Adapter for Kubernetes. The k8s-cloudwatch-adapter is an implementation of the Kubernetes Custom Metrics API and External Metrics API with integration for CloudWatch metrics. It allows you to scale your Kubernetes deployment using the Horizontal Pod Autoscaler (HPA) with CloudWatch metrics. 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.
