docker-py "Get http://: http: no Host in request URL" error when pulling docker image

[dvigueras]

From yesterday we cannot pull docker images using docker-py. It reports a missing http host error.

The closest related thing we've found is a missing serveraddress parameter value in docker remote API /auth: moby/moby#22254

 Version:      1.12.3

Server:
 Version:      1.12.3
 API version:  1.24
 Go version:   go1.6.3

docker-py versions we've tried with: 1.9.0 and 1.10.6

And here is the output error:

>>> import docker
>>> client = docker.from_env()
>>> client.pull('redis')
u'{"status":"Downloading from http://"}\r\n{"errorDetail":{"message":"Get http://: http: no Host in request URL"},"error":"Get http://: http: no Host in request URL"}\r\n'
>>>

Is anyone having the same issue?

Update: the issue here is the same issue present in #1321
docker-py is no working with requests-2.12.2, but it works fine with requests-2.12.1.

Temporary workaround: pip uninstall requests && pip install requests==2.12.1

Closing this issue as it has nothing to do with docker-py
