Module: Kitchen::Verifier::Terraform::ConfigureInspecRunnerAttributes

Extended by:
Dry::Monads::Either::Mixin, Dry::Monads::Maybe::Mixin, Dry::Monads::Try::Mixin
Defined in:
lib/kitchen/verifier/terraform/configure_inspec_runner_attributes.rb

Overview

Configures the InSpec profile attributes for the Inspec::Runner used by the verifier to verify a group.

Three different maps are merged to create the profile attributes.

The first map is comprised of attributes that are external to the Terraform state.

{
  "terraform_state" => "/path/to/terraform/state"
}

The second map is comprised of attributes that represent the Terraform output variables of the Terraform state. This map takes precedence in any key conflicts with the first map.

{
  "first_output_variable_name" => "first_output_variable_value",
  "second_output_variable_name" => "second_output_variable_value"
}

The third map is comprised of attributes defined by a group’s :attributes; the keys are converted to strings and the values are assumed to be Terraform output variable names which are resolved. This map takes precedence in any key conflicts with the second map.

{
  first_attribute_name: "second_output_variable_name"
}

# becomes

{
  "first_attribute_name" => "second_output_variable_value"
}
