Hello!

Ive got an issue when reinstalling Discourse.  
Here’s the error:

```plaintext
 (<unknown>): control characters are not allowed at line 1 column 1 -e LANG=en_US.UTF-8
YAML syntax error. Please check your containers/*.yml config files.

```

i used [yamllint](http://www.yamllint.com/) too check the config. here’s the result.
