Functions

func ID

func ID(root string) (string, error)

ID reads the worker id from the `workerid` file. If not exist, it creates a random one,

func Labels

func Labels(executor, snapshotter string) map[string]string

utility function. could be moved to the constructor logic?

Types

type Worker

type Worker struct {
	WorkerOpt
	CacheManager  cache.Manager
	SourceManager *source.Manager
	Cache         instructioncache.InstructionCache
	Exporters     map[string]exporter.Exporter
	ImageSource   source.Source
	CacheExporter *cacheimport.CacheExporter // TODO: remove
	CacheImporter *cacheimport.CacheImporter // TODO: remove

}

Worker is a local worker instance with dedicated snapshotter, cache, and so on. TODO: s/Worker/OpWorker/g ?

type WorkerOpt

type WorkerOpt struct {
	ID             string
	Labels         map[string]string
	SessionManager *session.Manager
	MetadataStore  *metadata.Store
	Executor       executor.Executor
