Hi Prefect Community, I just upgraded from 2.10.4 to 2.10.7. I used to use
Copy code
from prefect.packaging.docker import DockerPackager
docker = DockerPackager(
        dockerfile=str(Path("Dockerfile").resolve()),
        image_flow_location=flow_path,
        registry_url=config.get("AZURE_REGISTRY", "DOCKER_REGISTRY_URL"),
    )
docker_manifest = await docker.package(flow=flow)
to build and push images and use the manifest on kubernetes 
infra_overrides
. However the 
package
method is now raising issue.
Copy code
File "/home/dcvs/source_code/archimedes_etl_flows/.venv/lib/python3.10/site-packages/docker/api/client.py", line 221, in _retrieve_server_version
    raise DockerException(
docker.errors.DockerException: Error while fetching server API version: HTTPConnection.request() got an unexpected keyword argument 'chunked'

Reverting to 
2.10.6
fixes the issue.

Hm sounds like an incompatibility between Docker-py and the Docker server?
I don’t think we use 
chunked
ourselves
Also fun to see you’re using my Docker packager 😄
d
I use poetry and literally nothing has changed on the lock file for the docker
z
That’s so weird
d
Ive reverted to 2.10.6 pushed my flow changed while leaving my server and agents at 2.10.7 for now
z
What does 
pip freeze | grep docker
show before and after upgrading?
d
is that the new Env flag?
the one with HTTPv2 enable / diable
ah no its different
Testing it thanks
@Zanie Binding the requests version to 
<2.29.0
worked for me. Might be a good idea to push an announcement regarding the issue? Also regarding the docker package, as long as it works Ill use it 😄 👍
THank you!
