Monitoring Envoy and Edge Stack on Kubernetes with the Prometheus Operator

The text discusses the use of Prometheus Operator in monitoring Envoy, an open source L7 proxy, deployed at the edge using Kubernetes. It explains how the Prometheus Operator can be used to automatically create and manage Prometheus instances for monitoring purposes. Additionally, it introduces Ambassador, a Kubernetes-native API Gateway built on Envoy, which configures and manages Envoy instances in Kubernetes. The tutorial assumes that you are running Kubernetes 1.8 or later with RBAC enabled. It provides step-by-step instructions for deploying the Prometheus Operator, Ambassador, and other necessary components to monitor Envoy using Prometheus. Finally, it demonstrates how to test the setup by routing requests through Ambassador to the httpbin service.
