I’m building an emulator for Cloud Run. As I considered the solution, I assumed (more later) that I could implement Google’s gRPC interface for Cloud Run and use Envoy to proxy HTTP/REST requests to the gRPC service using Envoy’s gRPC-JSON transcoder.

Google calls this process Transcoding HTTP/JSON to gRPC which I think it a better description.

Google’s Cloud Run v2 (v1 is no longer published to the googleapis repo) service.proto includes the following Services definition for CreateService:

I have built Prometheus Exporters for multiple cloud platforms to track resources deployed across clouds:

• Prometheus Exporter for Azure
• Prometheus Exporter for crt.sh
• Prometheus Exporter for Fly.io
• Prometheus Exporter for GoatCounter
• Prometheus Exporter for Google Analytics
• Prometheus Exporter for Google Cloud
• Prometheus Exporter for Koyeb
• Prometheus Exporter for Linode
• Prometheus Exporter for PorkBun
• Prometheus Exporter for updown.io
• Prometheus Exporter for Vultr

Additionally, I’ve written two status service exporters:

• Prometheus Exporter for GCP Status
• Prometheus Exporter for Vultr Status

These exporters are all derived from an exemplar DigitalOcean Exporter written by metalmatze for which I maintain a fork.
