func CurrentTimestampAsString

func CurrentTimestampAsString() string

CurrentTimestampAsString returns the current time as milliseconds since the Unix epoch (e.g., "1519135679722")


type JobStatusClient

type JobStatusClient interface {

JobStatusClient is a client interface for updating the status of training jobs

func NewTrainerClient

func NewTrainerClient() JobStatusClient

NewTrainerClient ...

type TrainerClient

type TrainerClient interface {
	Client() grpc_trainer_v2.TrainerClient
	Close() error

TrainerClient is a client interface for interacting with the trainer service.

func NewTrainer

func NewTrainer() (TrainerClient, error)

NewTrainer create a new load-balanced client to talk to the Trainer service. If the dns_server config option is set to 'disabled', it will default to the pre-defined LocalPort of the service.

func NewTrainerWithAddress(addr string) (TrainerClient, error)

NewTrainerWithAddress create a new load-balanced client to talk to the Trainer service. If the dns_server config option is set to 'disabled', it will default to the pre-defined LocalPort of the service.

type TrainingStatusUpdate

type TrainingStatusUpdate struct {
	Status        grpc_trainer_v2.Status
	Timestamp     string
	ErrorCode     string
	StatusMessage string

TrainingStatusUpdate captures the details for training status update events

func GetStatus

func GetStatus(value string, logr *logger.LocLoggingEntry) *TrainingStatusUpdate

GetStatus converts between a string and proper DLaaS type of job status updates. The value parameter is either a status string (e.g., "PROCESSING"), or a JSON string with status and error details, e.g., '{"status":"FAILED","exit_code":"51","status_message":"Error opening ZIP file"}'
