Hi 👋, I'm new to Prefect and am testing the push work pools with Google Cloud Run. By going through the

how-to guide

, a push work pool was successfully provisioned. However, running the Prefect CLI generated example_deploy_script.py results the following error message, After restarting Docker Desktop on an Apple M2 machine, the error message remains the same. Any thoughts? Many thanks!

DockerException(docker.errors.DockerException: Error while fetching server API version: ('Connection aborted.', FileNotFoundError(2, 'No such file or directory')

Hmm. If you upgrade your Prefect version to 2.16.0 and rerun the script, do you now see an error about Docker not running? (we updated the error message that should appear if Docker isn’t running so that it’s more descriptive). Can you reach Docker from your CLI? e.g. with

docker run hello-world

?

Yes,

docker run hello-world

works well. The same result remains after reboot.

There are a few potential fixes in this Docker thread on working with Docker and Python that might be helpful

In the Docker Desktop, I noticed that the "default" builder was down due to some error. However, another builder, "desktop-linux" has been running and that's why images can still be built. Two questions 1) can Prefect use builders other than the "default" one? and 2) can Prefect uses Google Cloud Build instead? Thanks!

Hmm. I'm not sure. My quick look suggested the Linux builder wouldn't build an image on a Mac. Are you able to build images? Prefect is using the docker Python package under the hood, so I don't think there's a way to use Google Cloud Build. Alternatively, you can build your own Docker image and use it with a push work pool. Just specify it in the work pool.

Yes, images can be built. Rosetta is installed on my machine. Thanks for help. I'll give Serverless Infrastructure with Prefect Workers a try instead.
