opentelemetry-operator VS unified-observability-k8s-kubecon

We used Lightstep’s Prometheus Kubernetes OpenTelemetry Collector to get these Metrics into Lightstep. This Helm chart is inspired by kube-prometheus-stack, but with one crucial difference -- no Prometheus! We’re able to use recent enhancements to the OpenTelemetry Operator for Kubernetes such as support for Service Monitors in order to scrape Prometheus metrics from pods, system components, and more.

NOTE: If you want to follow along to see the full Terraform source code, you can check it out here. Even though the source code is specific to the Observability-Landscape-as-Code use case, the main Terraform concepts in this blog post can be ported over to other scenarios.

Create a Kubernetes cluster (GKE) in Google Cloud using the Google Terraform Provider. This is defined in the k8s module in our repo.
