docker.from_env() causes TypeError: load_config() got an unexpected keyword argument 'config_dict'

[w7089]

After upgrading docker to Server Version: 17.12.0-ce and docker-py to 3.0.1

Getting error:

Traceback (most recent call last):
File "", line 1, in
File "/usr/lib/python2.7/site-packages/docker/client.py", line 81, in from_env
**kwargs_from_env(**kwargs))
File "/usr/lib/python2.7/site-packages/docker/client.py", line 38, in init
self.api = APIClient(*args, **kwargs)
File "/usr/lib/python2.7/site-packages/docker/api/client.py", line 110, in init
config_dict=self._general_configs
TypeError: load_config() got an unexpected keyword argument 'config_dict'

When using simple call

import docker
c = docker.from_env()

Is it a known bug?
What version of docker-py is compatible with docker17.12.0-ce ?

Regards

P.S. downgrading to docker-py2.7 solves the issue

That's quite odd - config_dict is a valid argument for load_config in 3.x, so there's no reason that error should happen.

Is it possible you have different versions of the package interfering with one another, maybe inside / outside a virtualenv?

[stephan227]

I am running into the same problem. I had to downgrade to docker-py2.7. Currently using docker Version 17.12.0-ce-mac49

I fixed it by removing python and python packages and re-installing python. Installing the legacy docker-py package appears to cause issues when installed along the latest docker package.

[stephan227]

Yes, different versions caused an issue on my machine. I had to remove python and re-install it.

UPDATE:

Downgrading to docker==2.7.0 using pipenv install "docker<3" solves the issue

[shin-]

Fixed in 3.1.3

Have the same issue still with docker 3.3.0

You probably have old artifacts messing up your imports. Remove all docker and docker-py packages (inside/outside virtualenv) then reinstall.

[hushenbeg]

@shin- i am using python 3.6 version and trying to import the docker
and i got the

TypeError: load_config() got an unexpected keyword argument 'config_dict'

please tell me whats happing exactly inside the code

[w7089]

@shin- removed docker and docker-py packages, reinstalled docker and docker-py packages and getting the error still:

docker_client = docker.from_env()

python version is

On other system, your suggestion helped:

You can't have docker and docker-py in the same environment, they're incompatible.

[w7089]

i'm confused sorry, what should be installed then? just docker?
docker-py docs offers to run:

pip install docker
import docker

what is docker-py, then?

[geoffreywiseman]

I'm getting the sense that if I'm trying to use the docker module with Python2, I need to install "docker<3", but that's not covered by the module documentation anywhere that I can see? The README suggests to just install 'docker', and the pypi docs suggest 'docker' is compatible with Python2, but if I do that, I end up at this error.

[kleptog]

I'm getting this issue too. Not sure exactly why it's triggering, but I do notice there are two load_config functions:

/usr/local/lib/python2.7/dist-packages/docker/auth/auth.py:def load_config(config_path=None):
/usr/local/lib/python2.7/dist-packages/docker/auth.py:def load_config(config_path=None, config_dict=None):

Looking at the names of the files and directories I wonder if there is an importing order difference that causes it for some people to import the wrong module?

Also, this is the output of pip freeze:

docker==3.4.1
docker-compose==1.22.0
docker-py==1.10.6

Apparently docker is the replacement for docker-py, but does not conflict with it, so they simply install over each other. To fix this you have to uninstall both of them, then install just the right one. (And hope other pypi modules don't pull the old module).

Apparently docker is the replacement for docker-py, but does not conflict with it, so they simply install over each other.

I hit this running docker-compose after an upgrade of docker-compose, and filed docker/compose#6339 there. Seems worth preventing that failure mode.

Issue with airflow 2.1.0 was that it had some compatibility issues with python 3.8 even though Airflow suggests that it works fine with python 3.8, I switched to fresh python 3.6 installation and everything worked fine.
