type Service 

type Service struct {
	// contains filtered or unexported fields
}

Service exposes registry capabilities in the standard Engine interface. Once installed, it extends the engine with the following calls: 

'auth': Authenticate against the public registry
'search': Search for images on the public registry
'pull': Download images from any registry (TODO)
'push': Upload images to any registry (TODO)

func NewService 

func NewService(insecureRegistries []string) *Service

NewService returns a new instance of Service ready to be installed no an engine.

func (*Service) Auth 

func (s *Service) Auth(job *engine.Job) engine.Status

Auth contacts the public registry with the provided credentials, and returns OK if authentication was sucessful. It can be used to verify the validity of a client's credentials.

func (*Service) Install 

func (s *Service) Install(eng *engine.Engine) error

Install installs registry capabilities to eng.

func (*Service) Search 

func (s *Service) Search(job *engine.Job) engine.Status

Search queries the public registry for images matching the specified search terms, and returns the results.

Argument syntax: search TERM

Option environment: 

'authConfig': json-encoded credentials to authenticate against the registry.
	The search extends to images only accessible via the credentials.

'metaHeaders': extra HTTP headers to include in the request to the registry.
	The headers should be passed as a json-encoded dictionary.

Output: 

Results are sent as a collection of structured messages (using engine.Table).
Each result is sent as a separate message.
Results are ordered by number of stars on the public registry.
