#configure ⇒ Object

Configure all provisioned machines, adding any packages or settings required for SUTs

Raises:

  • (Exception) —

    Raise an exception if virtual machines fail to be configured

    end
  end
end

#provision ⇒ Object

Provision all virtual machines. Provision machines according to their set hypervisor, if no hypervisor is selected assume that the described hosts are already up and reachable and do no provisioning.

    @hosts << @machines[type]
  end

  @hosts
end

#provision?(options, host) ⇒ Boolean

Determine if a given host should be provisioned. Provision if:

  • only if we are running with —provision

  • only if we have a hypervisor

  • only if either the specific hosts has no specification or has ‘provision’ in its config

  • always if it is a vagrant box (vagrant boxes are always provisioned as they always need ssh key hacking)

Returns:

  • (Boolean)

  (command_line_says && host_says) or (host['hypervisor'] =~/vagrant/)
end

#validate ⇒ Object

Validate all provisioned machines, ensure that required packages are installed - if they are missing attempt to add them.

Raises:

  • (Exception) —

    Raise an exception if virtual machines fail to be validated
