Types

type Config

type Config struct {
	// HTTP port which JobMgr is listening on
	HTTPPort int `yaml:"http_port"`

	// gRPC port which JobMgr is listening on
	GRPCPort int `yaml:"grpc_port"`

	// FIXME(gabe): this isnt really the DB write concurrency. This is
	// only used for processing task updates and should be moved into
	// the storage namespace, and made clearer what this controls
	// (threads? rows? statements?)
	DbWriteConcurrency int `yaml:"db_write_concurrency"`

	// Task launcher specific configs
	Placement placement.Config `yaml:"task_launcher"`

	// GoalState configuration
	GoalState goalstate.Config `yaml:"goal_state"`

	// Preemption related config
	Preemptor preemptor.Config `yaml:"task_preemptor"`

	Deadline deadline.Config `yaml:"deadline"`

	// Job service specific configuration
	JobSvcCfg jobsvc.Config `yaml:"job_service"`

	// Watch API specific configuration
	Watch watchsvc.Config `yaml:"watch"`

	WorkflowProgressCheck progress.Config `yaml:"workflow_progress_check"`

	// Period in sec for updating active cache
	ActiveTaskUpdatePeriod time.Duration `yaml:"active_task_update_period"`

	// HostManagerAPIVersion is the API version that the Resource Manager
	// should use to talk to Host Manager.
	HostManagerAPIVersion api.Version `yaml:"hostmgr_api_version"`

	// ThemrosExecutor is config used to generate mesos CommandInfo / ExecutorInfo
	// for Thermos executor

}

Config is JobManager specific configuration

type Server

type Server struct {
	sync.Mutex

	ID string
	// contains filtered or unexported fields
}

Server contains all structs necessary to run a jobmgr server. This struct also implements leader.Node interface so that it can perform leader election among multiple job manager server instances.

func NewServer

func NewServer(
	httpPort, grpcPort int,
	jobFactory cached.JobFactory,
	goalstateDriver goalstate.Driver,
	taskPreemptor preemptor.Preemptor,
	deadlineTracker deadline.Tracker,
	placementProcessor placement.Processor,
	statusUpdate event.StatusUpdate,
	backgroundManager background.Manager,
	watchProcessor watchsvc.WatchProcessor,
) *Server

NewServer creates a job manager Server instance.

func (*Server) GainedLeadershipCallback

func (s *Server) GainedLeadershipCallback() error

GainedLeadershipCallback is the callback when the current node becomes the leader

func (*Server) GetID

func (s *Server) GetID() string

GetID function returns jobmgr app address. This implements leader.Nomination.

func (*Server) HasGainedLeadership

func (s *Server) HasGainedLeadership() bool

HasGainedLeadership returns true iff once GainedLeadershipCallback completes

func (*Server) LostLeadershipCallback

func (s *Server) LostLeadershipCallback() error

LostLeadershipCallback is the callback when the current node lost leadership

func (*Server) ShutDownCallback

func (s *Server) ShutDownCallback() error

ShutDownCallback is the callback to shut down gracefully if possible
