Instance Method Details

#from_file(filename, cookbook_name) ⇒ Object

Add a input to the input collection. The cookbook_name needs to be determined by the caller and is used in the `include_input` API to match on. The path should be the complete path on the host of the yml file, including the filename.

Parameters:

def from_file(filename, cookbook_name)
  new_input = Input.from_file(events, filename, cookbook_name)
  self << new_input
  events.compliance_input_loaded(new_input)
end

#from_hash(hash) ⇒ Object

Add a input from a raw hash. This input will be enabled by default.

def from_hash(hash)
  new_input = Input.from_hash(events, hash)
  new_input.enable!
  self << new_input
end

#include_input(arg) ⇒ Object

DSL method to enable input files. This matches on the filename of the input file. If the specific input is omitted then it uses the default input. The string supports regular expression matching.

include_input “acme_cookbook::ssh-001”

include_input “acme_cookbook”

include_input “acme_cookbook::.*”

include_input “acme_cookbook::ssh.*”

include_input “.::ssh.

include_input({ “ssh_custom_path”: “/usr/local/bin” })

Examples:

Specific input file in a cookbook

The compliance/inputs/default.yml input in a cookbook

Every input file in a cookbook

Matching inputs by regexp in a cookbook

Matching inputs by regexp in any cookbook in the cookbook collection

Adding an arbitrary hash of data (not from any file in a cookbook)
