I am receiving this error message in Google Cloud Shell:
Service usage limits temporarily exceeded. Try connecting later.
What are the applicable usage limits for Cloud Shell?
For background: I have been running quite a few docker builds inside Cloud Shell, and will probably run those on a VM instance of my own in the future. But in order to proceed I need renewed access to Cloud Shell for exporting my current files from its local file system. "Later" apparently means "at least several hours".
UPDATE I did not find any documentation on this usage limit by Google. In practical terms, it showed up twice after approx. a week of intense use of Google Cloud Shell (esp. for building Docker images) in each case and went away after approx. 2 days of inactivity.
I've now switched to (sshing into) a private VM instance instead of Google Cloud Shell. Again in practical terms, a GKE cluster node (as in gcloud container clusters) serves best, because a "raw" GCE VM instance does not have docker installed. On a GKE cluster node, sudo docker build succeeds but unfortunately and for yet unclear reasons sudo docker push fails with denied: Access denied. after pushing a few layers.

Google offers Container-Optimized OS which is optimized to run Docker containers however this is still in Beta phase. More information about it can be found in this Help Center article.
However, for the Cloud Shell usage limits, as Carlos mentioned in the comment the following documentation explains the usage limits but doesn't provide specific threshold and if your session is terminated or cannot be established because you exceeded a service limit, Cloud Shell will display an error with a link to a form that allows you to appeal the limit violation. Click the feedback link and submit the form with more information about the tasks you were performing before your session was terminated.
