OSX - 'str' object does not support item assignment

[semperos]

System specs:

• Mac OSX 10.8.5
• Python 2.7.2 (built-in)
• Fig 0.2.2

My fig.yml:

image: stackbrew/ubuntu
ports:
  - 3306:3306
  - 6379:6379
links:
   - mysql
   - redis
mysql:
  image: orchardup/mysql
redis:
  image: orchardup/redis

When running fig up, I get the following error:

Traceback (most recent call last):
  File "/usr/local/bin/fig", line 9, in <module>
    load_entry_point('fig==0.2.2', 'console_scripts', 'fig')()

    service['name'] = service_name
TypeError: 'str' object does not support item assignment

I tried removing everything from the fig.yml shy of the image entry, and the same error occurs regardless. Any help would be greatly appreciated.

Everything in your fig.yml needs to be inside a service. So if, for example, your main service is a web app, it should look like this:

web:
  image: stackbrew/ubuntu
  ports:
    - 3306:3306
    - 6379:6379
  links:
    - mysql
    - redis
mysql:
  image: orchardup/mysql
redis:
  image: orchardup/redis

We should throw a better error message here though, so I'm going to leave this open.

There I go, not reading the documentation carefully enough. Thank you for a polite response and for taking the effort to improve the error messages.

No worries – thanks for helping debug!

Is there any part of the documentation that wasn't clear enough that we could improve?

Not sure I have specific changes I would make to your docs, but I can explain how I misread them. I thought the idea of the fig.yml was to define a primary service that might happen to be backed by other, auxiliary services, like MySQL or Redis, in which case I didn't even see the web key in the example fig.yml and thought top-level entries were for the main application image/container. The fact that everything is defined in a service makes sense.
