AttributeError: 'list' object has no attribute 'items' for all docker-compose commands

[tippenein]

Every docker-compose command fails with AttributeError: 'list' object has no attribute 'items'

My docker-compose looks like this:

db:
  image: postgres:9.4
  ports:
    - "5432"
web:
  build: .
  command: yesod devel
  environment:
    - HOST=0.0.0.0
    - PGUSER=postgres
    - PGPASS
    - PGHOST=db
  stdin_open: true
  volumes:
   - .:/app
  ports:
   - "3000:3000"
  links:
   - db

Probably related to #129. Please include the version you're using and possibly the rest of the stack trace.

docker-compose v1.1.0

It works if I remove the db portion.

web:
  build: .
  command: yesod devel
  stdin_open: true
  volumes:
    - .:/usr/src/app
  ports:
    - "3000:3000"

The rest of the traceback looks like

  File "<string>", line 3, in <module>
  File "/Users/dec/projects/fig/build/docker-compose/out00-PYZ.pyz/compose.cli.main", line 34, in main
  File "/Users/dec/projects/fig/build/docker-compose/out00-PYZ.pyz/compose.cli.docopt_command", line 21, in sys_dispatch

I'm pretty sure you're right about it being related to #129 but I'll include details for people possibly running into similar problems

We've fixed some bugs around environment variables in the last couple of releases. I'd suggest trying with version 1.3.0 to see if it's fixed.

the 1.3.1 release fixes this issue
