Configuration file style guide

To make a configuration file more reusable:

• Use values from Pillar data, instead of hardcoding values.

• Set sensible defaults, for example:

  {{ bind_address|default('127.0.0.1') }}
  

  If the key contains a hyphen:

  {{ entry.uwsgi.max-requests|default(1000) }}
  

• Make values optional, for example:

  {%- if 'cheaper' in entry.uwsgi %}
  cheaper = {{ entry.uwsgi.cheaper }}
  {%- endif %}
