I’ve written a basic discoverer of Google Cloud Run services. This is for a project and it extends work done in some previous posts to Multiplex gRPC and Prometheus with Cloud Run and to use Consul for Prometheus service discovery. This solution: Accepts a set of Google Cloud Platform (GCP) projects Trawls them for Cloud Run services Assumes that the services expose Prometheus metrics on :443/metrics Relabels the services Surfaces any discovered Cloud Run services’ metrics in Prometheus You’ll need Docker and Docker Compose.

I’m working on a project that will programmatically create Google Cloud Run services and I want to be able to dynamically discover these services using Prometheus. This is one solution. NOTE Google Cloud Run is the service I’m using, but the principle described herein applies to any runtime service that you’d wish to use. Why is this challenging? IIUC, it’s primarily because Prometheus has a limited set of plugins for service discovery, see the sections that include _sd_ in Prometheus Configuration documentation.
