get_config_header error on mac #1353

What am I doing wrong?

Hey folks, please heed the following recommendations when reporting issues: https://github.com/docker/docker-py/blob/master/CONTRIBUTING.md#reporting-issues

I can't help you if I don't know what version you're running.

shin- · 2016-12-13T20:36:37Z

You may need to uninstall the docker-py package as it may be conflicting with the new docker package.

pip uninstall docker docker-py
pip install docker

Let me know if it helps.

renatoriccio · 2016-12-13T20:40:59Z

Hi @shin- , thanks a lot for your help it works again now!

xyalan · 2016-12-26T18:41:21Z

I have same problem, @shin- Thanks.

RonnyPfannschmidt · 2017-04-06T08:35:02Z

@shin- i can replicate the issue.

docker-py was installed, pip install docker would use the wheel and not catch the error
$ pip install docker-py docker
will succeed, afterwards i get

E               AttributeError: 'module' object has no attribute 'get_config_header'

.../site-packages/docker/api/image.py:358: AttributeError
>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>> entering PDB >>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>

(Pdb) auth.auth
<module 'docker.auth.auth' from '.../site-packages/docker/auth/auth.pyc'>
(Pdb)

its only fixable by uninstalling both packages and reinstalling docker

in order to protect users i suggest to move the check from setup.py to docker/__init__.py
in modern times setup.py is not executed at all since pip uses wheels if possible and aggressively caches wheels locally as well

Handle docker/docker-py#1353

adiroiban · 2017-07-23T22:36:30Z

So, I fixed this by removing the leftover files after an upgrade

rm -rf YOUR-PYTHON/site-packages/docker/auth/

I have upgraded from 1.6 to 2.4.2

Long story here

I got this error when I try to run a container for an image which does not exists.

here is the test_docker.py code

import docker
client = docker.DockerClient(
    base_url='tcp://localhost:2375',
    version='1.24',
    timeout=2,
    tls=False,
    )
client.containers.run(
    image='no-such-image:exp',
    detach=True
    )

and here is the output

$ ./build-ubuntu1604-x64/bin/python test_docker.py 
Traceback (most recent call last):
  File "test_docker.py", line 10, in <module>
    detach=True
  File "/home/adi/chevah/server/build-ubuntu1604-x64/lib/python2.7/site-packages/docker/models/containers.py", line 699, in run
    self.client.images.pull(image)
  File "/home/adi/chevah/server/build-ubuntu1604-x64/lib/python2.7/site-packages/docker/models/images.py", line 273, in pull
    self.client.api.pull(name, tag=tag, **kwargs)
  File "/home/adi/chevah/server/build-ubuntu1604-x64/lib/python2.7/site-packages/docker/api/image.py", line 358, in pull
    header = auth.get_config_header(self, registry)
AttributeError: 'module' object has no attribute 'get_config_header'

I done some debugging and i got

(Pdb) auth.__file__
(Pdb) '/home/adi/chevah/server/build-ubuntu1604-x64/lib/python2.7/site-packages/docker/auth/__init__.pyc'
dir(auth)
(Pdb) ['INDEX_NAME', 'INDEX_URL', '__builtins__', '__doc__', '__file__', '__name__', '__package__', '__path__', 'auth', 'encode_header', 'load_config', 'resolve_authconfig', 'resolve_repository_name']

While checking the upstream code for release 2.4.2 https://github.com/docker/docker-py/tree/2.4.2-release/docker I saw that there is no auth package... only a module.

So, it looks like the trouble is from a bad upgrade.

Manual cleanup and all is good :)

Hi, is this still an open bug since Dec 2016? I have same issues, I logged this issue, ansible/ansible#34851, but ansible closed it and referred my back to this issue. I have no clue how to move forward, is docker still working on this issue? Or is it an ansible issue?

docker on the Managed Host:

docker --version
Docker version 18.01.0-ce, build 03596f5

Ansible on the Mac Controller:

ansible --version
ansible 2.4.2.0
ansible python module location = /Library/Python/2.7/site-packages/ansible
python version = 2.7.10 (default, Jul 15 2017, 17:16:57) [GCC 4.2.1 Compatible Apple LLVM 9.0.0 (clang-900.0.31)]

Python on the RPi

python --version
Python 2.7.13

With the above setup, docker_image works, but docker_container does not work.

This is after I removed docker-py from the RPi, cleaned up after .../site-packages/auth,
I also tried downgrading as per other suggestions:

pip uninstall docker docker-py ; pip install docker==2.0.1

But, sadly cannot get docker_container to work as well, still getting:

"Failed to import docker-py - No module named requests.exceptions. Try `pip install docker-py`"

But if I pip install docker-py on the 'managed host' or remove it and install pip install docker this does not work.

Where to from here?

IoTPlay · 2018-01-18T16:55:10Z

According to ansible/ansible#20492, for Failed to import docker-py for docker_container module, now also tried one of @jpriron 's suggestions, also not working:

pip uninstall docker
pip uninstall docker-py
pip uninstall docker-compose
pip install docker-compose==1.9.0

Just note, these suggestions dates back a year....

An further down, @jpiron suggests, unlike others, to uninstall docker and install docker-py again...

pip uninstall docker
pip install --ignore-installed docker-py

Sadly, ... still the same error.

Furtherdown, @appleman suggest: (on the 'managed host')

pip uninstall docker
pip uninstall docker-py
pip install docker

But sadly, same error.

Furtherdown, @appleman suggests to run the playbook with Python3, have no idea how to do this, will study it now...

And I solved it by run playbook under python3.

Furtherdown, @antoinetran clarifies, docker for python3, docker-py for python2.7, so back to the drawing board.

pip uninstall docker docker-py docker-compose
pip install docker-compose

Nope, still not working...., and versions are:

$ pip freeze | grep docker
docker==2.7.0
docker-compose==1.18.0
docker-pycreds==0.2.1
dockerpty==0.4.1

What now?????

RonnyPfannschmidt · 2018-01-18T17:29:39Z

check for a docker folder in your site packages after uninstalling everything, if its still there its the cause

part of this issue is partial metadata corruptio

IoTPlay · 2018-01-18T18:45:02Z

Thank you Ronny, should I then just delete this docker folder - will that
be enough ?

I checked, pip uninstalled all docker* modules, none left in the folder

~/.local/lib/python2.7/site-packages

IoTPlay · 2018-01-20T09:40:47Z

Dear all, I resolved my controller on Mac, Target on Pi with a test playbook.

I created a test bench from Mac to RPi with docker_login, docker_image, docker_container and docker_service. See it here:

https://github.com/IoTPlay/docker-iotplay-standards/blob/master/10_Test_docker-with-ansible.yml

All my tests pasts, after recreated a Pi from scratch, instructions in the above link as well. I used the standard pi user, and not a user I created myself through ansible. I will not have to go check what I missed out for this created user.

The instructions in the above link, installs the stock standard python programs on the TARGET (pi) machine, not using sudo.

$  sudo apt install python-pip
$  pip install docker-py
$  pip install docker-compose

Apologies for the 'noise' from me in this issue, maybe this can assist others.
Jéan.

RonnyPfannschmidt · 2018-01-20T18:27:11Z

@IoTPlay docker-compose depends on docker, not on docker-py - so installing docker-py beforehand will ensure a broken install in all cases,

please skip docker-py

IoTPlay · 2018-01-22T06:59:00Z

Ronny, your comment above is the most important statement of this -and ansible's multitude of issues logged. I wish they will update their software to not ask for the installation of docker-py, it cost me 3 weeks of investigations.

please skip docker-py

Thank you for your assistance.

RonnyPfannschmidt · 2018-01-22T08:32:30Z

@IoTPlay im glad my suggestion helped, please report this to ansible itself, perhaps linking this issue

note that there may be a unintended legacy requirement (changed apis between docker and docker-py)

in any case it would help if that mismatch was documented in a more discoverable fashion
