Hey all, noob question - I’m trying to run through the hello world tutorial but using Docker on a VPS instead of locally and I get
Copy code
404 Client Error for <http+docker://localhost/v1.40/containers/create>: Not Found ("No such image: prefecthq/prefect:0.14.7")
Did I do something wrong or is this related to the new 14.7 release that I see on GitHub?

Hi @Gareth Dwyer - this is most likely caused by your docker daemon’s configuration; can you try running
docker run -it prefecthq/prefect:0.14.7 bash
and see if you get the same error?

ah thanks that gives a much more actionable error that I assume might be related 😅
Copy code
docker: failed to register layer: Error processing tar file(exit status 2): fatal error: runtime: out of memory

will try a beefier VPS

ahh yup there it is! FYI in case you run into future issues, Prefect uses the Docker Python SDK to connect directly to your machine’s docker daemon. There are a few bits of configuration that sometimes need tweaking (especially when running in CI systems) but otherwise if you see a docker error you can usually debug further with the docker CLI directly
