func (m *Mosn) Wait()

type StageManager

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

StageManager is a stage manager that controls startup stages running. We divide the startup into six stages: 1. The parameters parsed stage. In this stage, parse different parameters from cli.Context, and finally call config load to create a MOSNConfig. 2. The initialize stage. In this stage, do some init actions based on config, and finally create a MOSN object. 3. The pre-startup stage. In this stage, creates some basic instance from MOSN object. 4. The startup stage. In this stage, do some startup actions such as connections transfer for smooth upgrade and so on. 5. The after-start stage. In this stage, do some other init actions after startup. 6. The after-stop stage. In this stage, do some clean up actions after mosn closed. The difference between pre-startup stage and startup stage is that startup stage has already accomplished the resources that used to startup mosn.

func NewStageManager

func (*StageManager) Run

func (stm *StageManager) Run()

Run blocks until the mosn is closed

func (*StageManager) Stop

func (stm *StageManager) Stop()

free resourse at the end TODO: may introduce other stages here, like: "before-stop", "stop".

func (*StageManager) WaitFinish
