Overview

Writing an actor

All actors should inherit from Sprinkle::Actors::Actor. Actors must provide the following methods:

  • #install (installer, roles, options)

  • #verify (verifier, roles, options)

  • #servers_for_role? (roles)

  • #sudo?

  • #sudo_command

Hopefully these methods are kind of fairly obvious. They should return true to indicate success and false to indicate failure. The actual commands you need to execute can be retrived from installer.install_sequence and verifier.commands.
