Hi all. I'm trying to implement a docker storage flow on a prefect server instance on a workstation in our network. I build a custom docker base image and push it to docker.io. However, I get an error registering my flow... Not sure where this might originate?

requests.exceptions.HTTPError: 404 Client Error: Not Found for url: <http+docker://localhost/v1.40/images/create?tag=0.13.19-python3.9&fromImage=prefecthq%2Fprefect>

more trace ...

File "/Users/werner-ch/.pyenv/versions/3.9.0/envs/dataflow/lib/python3.9/site-packages/docker/errors.py", line 31, in create_api_error_from_http_exception
    raise cls(e, response=response, explanation=explanation)
docker.errors.NotFound: 404 Client Error for <http+docker://localhost/v1.40/images/create?tag=0.13.19-python3.9&fromImage=prefecthq%2Fprefect>: Not Found ("manifest for prefecthq/prefect:0.13.19-python3.9 not found: manifest unknown: manifest unknown")

Would anyone know where I should start digging? My base image is: https://hub.docker.com/r/cwerner/dataflow

We may not be publishing a python 3.9 docker image yet as it’s our extra extensions don’t support python 3.9.

ah ok. will switch to 3.8 - no problem

I believe that is just the docker client talking to the local docker “server”

ok, cool... thanks! will report back to this thread if this fixed it
