got this error when trying to shut down my project.

I'm also getting this error pretty regularly now. Have tried rebuilding with fig build --no-cache, tried removing all Docker containers/images, etc. I get the same error when trying to run fig up.

@chriscohoat I believe this is unrelated to the original issue (very different stack traces), but is possibly easier to track down. Could you paste your fig.yml?

I suspect you have something like volumes: (with no value), which is realted to #129 (improve validation of the fig.yml).

[dnephin]

@samphippen is this something you're able to reproduce, or a one-time occurrence? From the stack trace it looks like an error pretty deep in a core module. Did it end up killing all the containers or did this crash prevent it from killing some?

[chriscohoat]

@samphippen you are absolutely correct, my fig.yml had volumes: with no value. If you want me to remove my comment to keep this issue clean let me know. Thanks!

[jamshid]

Yes, in my case, I had an empty environment in fig.yml. Feeding google with the new docker-compose stack trace.

  environment:
    -

I think I found a similar issue with docker-compose. Let me know if not directly related and I'll open a separate issue.

and my docker-compose.yml looked like this:

db:
  image: postgres

portal:
  build:
  links:
    - db
  ports:
    - "8000:8000"
  volumes:
    - .:/

It seems to work fine when I add a period (.) after build: like this:

db:
  image: postgres

portal:
  build: .
  links:
    - db
  ports:
    - "8000:8000"
  volumes:
    - .:/

[li0nel]

Got the same problem, reinstalled compose and boot2docker, but it was just a malformed docker-compose.yml...

[dnephin]

There area few different issues being reported here.

The config validation issues should be resolved by #129 in the 1.5.0 release.
The original issue was most likely a bug in requests, which we've upgraded a couple times since this issue was created.
