Docker-py: Max retries exceeded with url

[wangzhezhe]

Hi,
when I'm trying to get information from the docker host just like this:

c= docker.Client(base_url='http://10.82.81.165:1414',version='1.10',timeout=20)
c.images()

I got the mistake:
File "/home/wangzhe/workspace/testDjango/testDjango/init.py", line 7, in
c.images()
File "/usr/local/lib/python2.7/dist-packages/docker/client.py", line 515, in images
res = self._result(self._get(self._url("/images/json"), params=params),
File "/usr/local/lib/python2.7/dist-packages/docker/client.py", line 74, in _get
return self.get(url, *_self._set_request_timeout(kwargs))
File "/usr/local/lib/python2.7/dist-packages/requests/sessions.py", line 468, in get
return self.request('GET', url, *_kwargs)
File "/usr/local/lib/python2.7/dist-packages/requests/sessions.py", line 456, in request
resp = self.send(prep, *_send_kwargs)
File "/usr/local/lib/python2.7/dist-packages/requests/sessions.py", line 559, in send
r = adapter.send(request, *_kwargs)
File "/usr/local/lib/python2.7/dist-packages/requests/adapters.py", line 375, in send
raise ConnectionError(e, request=request)
requests.exceptions.ConnectionError: HTTPConnectionPool(host='10.82.81.165', port=1414): Max retries exceeded with url: /v1.10/images/json?only_ids=0&all=0 (Caused by : [Errno 111] Connection refused)
Could anyone give me some suggestions?
Thank you!

It's likely that you're connecting to the wrong IP/port, or you're behind a firewall of some sort. Check your setup to make sure that's not the case!

[wangzhezhe]

Thanks for your suggestion!
My docker deamon didn's listen to the right ports,I was already fixed that problem.

I get a similar error when I try to connect to docker daemon after using the remove_container method. My output is:

@anselal you're connecting to docker engine running on 127.0.0.1:2375 but your flask app is not able to connect. Can you verify that engine is running on the port and accepting connections? This can be easily done with curl:

$ curl -v 127.0.0.1:2375/info

[anselal]

I am actually using unix socket to connect to docker. I do not understand why it tries to reconnect to the daemon with tcp.

[TomasTomecek]

This is the code of docker-py which results into failure:

File "/home/anselal/docker-isthmos/app/views.py", line 21, in docker_images
  images = client.images()

How's the client being initiated?

[anselal]

from docker import Client
client = Client(base_url='unix://var/run/docker.sock')

[TomasTomecek]

But the exception mentions localhost, not unix socket. Looks like the app either
a) changes the base_url of client instance
b) initiates client multiple times

Anyway, this is certainly not an issue of docker-py.

[anselal]

Well, ok. I will try to debug it. Thanks anyways

Could anyone HELP ME please!

[GaryLBaird]

Did you ever resolve this? I have the same problem and I am fairly new to Docker as well. I'm running ubuntu on hyper-v with docker and the ExposeVirtualizationExtensions set to true. And it seems to work for the most part.
Powershell: Hyper-V Configuration command for Exposing Virtualization to the VM.
"Set-VMProcessor "Ubuntu 18.04.1 LTS" -ExposeVirtualizationExtensions $true"

To me, this looks like an issue with port or routing issue. When I run curl I get Connection refused on the port.
curl -v 127.0.0.1:2376
