Running computations >60min on Google Cloud Run

Cloud Run currently has a configurable maximum request timeout of 3,600 seconds. There is no supported method around that today.

Requests do not run in the background, so you cannot periodically ping the service to keep a task running.

Google will soon be offering Cloud Run Jobs. This is currently in preview. I do not know the release timeframe.

Cloud Run Jobs enable you to run data processing and other run-to-completion workloads in Cloud Run, with the same simple developer experience and fast startup and scale-out of Cloud Run

Note: There is a signup link for Cloud Run Jobs. I do not know if I can share the link on a forum. Sometimes preview features are by invitation only.
