func (*RunnerParams) CheckRegistryImages

func (cp *RunnerParams) CheckRegistryImages(isInternal bool) error

Check the external runner images between local and remote repositories. If local exists but remote does not then do nothing If local exists and is the same as the remote then do nothing If local is older than remote then give user the option to download the remote If neither exists then fail immediately

func (*RunnerParams) RunDockerController

func (cp *RunnerParams) RunDockerController(statusOnly bool)

RunDockerController is commander-in-chief of external runners. It is called from Wercker CLI to start or stop external runners. The Wercker CLI builds the RunnParams and calls this function.
