Seems like a versioning issue with a dependency, where a basic timeout value is expected, but an object is sent instead. Any ideas? Thanks!

I just did the same thing (on python 2.7) and it worked for me, here's my pip freeze to compare versions:

PyYAML==3.11
argparse==1.2.1
docker-py==0.5.3
dockerpty==0.3.2
docopt==0.6.2
fig==1.0.1
requests==2.4.3
six==1.8.0
texttable==0.8.1
websocket-client==0.11.0

docker-py and requests are likely the two relevant ones.

[jesselang]

$ python --version
Python 2.7.8

Here's pip freeze.

PyYAML==3.11
argparse==1.2.1
docker-py==0.5.3
dockerpty==0.3.2
docopt==0.6.2
fig==1.0.1
requests==2.4.3
six==1.8.0
texttable==0.8.1
urllib3==1.9.1 # since this is mentioned in the backtrace
websocket-client==0.11.0

Appears to be identical. What can I look at next?

[jesselang]

If I don't have a fig.yml, fig ps works.

Here's the fig.yml I'm using:

web:
  image: wordpress
  ports:
    - "8000:8000"

Could it be getting the image that is the problem? I'm completely new to fig.

I would suspect either something weird about installing things with pip -U, or some environment variable?

Maybe try in a virtualenv? or look for things in env | grep -i http

[jesselang]

$ env | grep -i http

is empty. I'll try a virtualenv next.

[jesselang]

Using a virtualenv worked. That's rather strange. Adds another step to my workflow, but better than not having a working environment. Thanks for your help!

Seems that this can still happen if you're using an older urllib3 library which ubuntu appears to still ship.
