Instance Method Details

#from_file(filename, cookbook_name) ⇒ Object

Add a waiver to the waiver collection. The cookbook_name needs to be determined by the caller and is used in the ‘include_waiver` 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_waiver = Waiver.from_file(events, filename, cookbook_name)
  self << new_waiver
  events&.compliance_waiver_loaded(new_waiver)
end

#from_hash(hash) ⇒ Object

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

def from_hash(hash)
  new_waiver = Waiver.from_hash(events, hash)
  new_waiver.enable!
  self << new_waiver
end

#include_waiver(arg) ⇒ Object

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

include_waiver “acme_cookbook::ssh-001”

include_waiver “acme_cookbook”

include_waiver “acme_cookbook::.*”

include_waiver “acme_cookbook::ssh.*”

include_waiver “.::ssh.”

include_waiver({ “ssh-01” => 

"expiration_date" => "2033-07-31",
"run" => false,
"justification" => "the reason it is waived",

})

Examples:

Specific waiver file in a cookbook

The compliance/waiver/default.rb waiver file in a cookbook

Every waiver file in a cookbook

Matching waivers by regexp in a cookbook

Matching waivers by regexp in any cookbook in the cookbook collection

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