Instance Method Summary collapse
-
#call(state) ⇒ Object
Runs the verifier on the instance.
-

-
#doctor(state) ⇒ Object
Check system and configuration for common errors.
-
#init_command ⇒ String
Generates a command string which will perform any data initialization or configuration required after the verifier software is installed but before the sandbox has been transferred to the instance.
-
#initialize(config = {}) ⇒ Base
constructor
Creates a new Verifier object using the provided configuration data which will be merged with any default configuration.
-
#install_command ⇒ String
Generates a command string which will install and configure the verifier software on an instance.
-
#prepare_command ⇒ String
Generates a command string which will perform any commands or configuration required just before the main verifier run command but after the sandbox has been transferred to the instance.
-
#run_command ⇒ String
Generates a command string which will invoke the main verifier command on the prepared instance.
-
#sandbox_path ⇒ String
Returns the absolute path to the sandbox directory or raises an exception if ‘#create_sandbox` has not yet been called.

Class Method Details
.kitchen_verifier_api_version(version) ⇒ Object
Sets the API version for this verifier. If the verifier does not set this value, then ‘nil` will be used and reported.

#cleanup_sandbox ⇒ Object
Deletes the sandbox path. Without calling this method, the sandbox path will persist after the process terminates. In other words, cleanup is explicit. This method is safe to call multiple times.

# File 'lib/kitchen/verifier/base.rb', line 96 def cleanup_sandbox return if sandbox_path.nil? debug("Cleaning up local sandbox in #{sandbox_path}") FileUtils.rmtree(sandbox_path) end |
#create_sandbox ⇒ Object
Creates a temporary directory on the local workstation into which verifier related files and directories can be copied or created. The contents of this directory will be copied over to the instance before invoking the verifier’s run command. After this method completes, it is expected that the contents of the sandbox is complete and ready for copy to the remote instance.
Note: any subclasses would be well advised to call super first when overriding this method, for example:

#init_command ⇒ String
Generates a command string which will perform any data initialization or configuration required after the verifier software is installed but before the sandbox has been transferred to the instance. If no work is required, then ‘nil` will be returned.

Generates a command string which will install and configure the verifier software on an instance. If no work is required, then ‘nil` will be returned.
