Access Google Services using gRPC
Google publishes interface definitions of Google APIs (services) that support REST and gRPC in a repo called Google APIs. Google’s SDKs uses gRPC to access these services but, how to do this using e.g. gRPCurl?
I wanted to debug Cloud Profiler and its agent makes UpdateProfile RPCs to cloudprofiler.googleapis.com. Cloud Profiler is more challenging service to debug because (a) it’s publicly “write-only”; and (b) it has complex messages. UpdateProfile sends UpdateProfileRequest messages that include Profile messages that include profile_bytes which are gzip compressed serialized protos of pprof’s Profile.

Google Trillian on Cloud Run
I’ve written previously (Google Trillian for Noobs) about Google’s interesting project Trillian and about some of the “personalities” (e.g. PyPi Transparency) that I’ve build using it.
Having gone slight cra-cra on Cloud Run and gRPC this week with Golang gRPC Cloud Run and gRPC, Cloud Run & Endpoints, I thought it’d be fun to deploy Trillian and a personality to Cloud Run.
It mostly (!) works :-)
At the end of the post, I’ve summarized creating a Cloud SQL instance to host the Trillian data(base).

gRPC, Cloud Run & Endpoints
<3 Google but there’s quite often an assumption that we’re all sitting around the engineering table and, of course, we’re not.
Cloud Endpoints is a powerful offering but – IMO – it’s super confusing to understand and complex to deploy.
If you’re familiar with the motivations behind service meshes (e.g. Istio), Cloud Endpoints fits in a similar niche (“neesh” or “nitch”?). The underlying ambition is that, developers can take existing code and by adding a proxy (or sidecar), general-purpose abstractions, security, logging etc.

Golang gRPC Cloud Run
Update: 2020-03-24: Since writing this post, I’ve contributed Golang and Rust samples to Google’s project. I recommend you start there.
Google explained how to run gRPC servers with Cloud Run. The examples are good but only Python and Node.JS:
gRPC comes to Cloud Run gRPC in Google Cloud Run Missing Golang…. until now ;-)
I had problems with 1.14 and so I’m using 1.13.
Project structure I’ll tidy up my repo but the code may be found:
