Config initializers allow you to hook early into the Terraspace boot process. This provides a way of customizing Terraspace beyond the config/app.rb options. Generally, recommend using config options when possible and reaching for config initializers for advanced usage.
Here’s a simple example:
Terraspace::Layering.module_eval do def pre_layers [ ENV['TEAM'], ] end end
This example customizes Terraspace layering processing. More info: Custom Layering.
Config initializers are a generalized system, so the way you use it really depends on what you’re trying to do.
