The port number of the dashboard supports automatic selection.

[imneov]

Describe the proposal

The port of the dashboard should support automatic selection. When the --port flag is set to 0, a free port will be randomly found to start the dashboard to ensure that there will be no port conflicts.

Release Note

RELEASE NOTE:

• [x] the --port flag could be set to 0, In this case, dashboard will server on a random port which is free.

We can update portforward.LocalPort use fw.GetPorts() when portforward is Ready.

failure := make(chan error)
go func() {
	if err := fw.ForwardPorts(); err != nil {
		failure <- err
	}
}()

select {
// if `fw.ForwardPorts()` succeeds, block until terminated
case <-pf.ReadyCh:
	ports, err := fw.GetPorts()
	if err == nil && len(ports) > 0{
		pf.LocalPort = int(ports[0].Local)
		pf.RemotePort = int(ports[0].Remote)
	}
// if failure, causing a receive `<-failure` and returns the error
case err := <-failure:
	return err
}
