How to allow TCP traffic in GCP Cloud Run?

I've built a Go binary for handling SSH traffic. And deployed it to Cloud Run.

Looks like cloud run allows only HTTP traffic, and my attempts to connect via ssh -p 80 ***.run.app fails.

How to allow SSH traffic to be passed through? I assume I need to allow TPC connections some how?

Thanks in advance.

  • You can't SSH to Cloud Run as it being serverless. Cloud Run can only receive HTTP requests based on this documentation on invoking with an HTTPS Request.

    As mentioned by @guillaume blaquiere, container is immutable and instance is ephemeral as Cloud Run being a serverless containerized microservices. Once the instance has been deleted or destroyed, you won't be able to access it as Cloud Run would just create a new one.

    It is highly recommended to check out @John Hanley's documentation, as well as the following for your references regarding how Cloud Run works:
