示例1: startInstance

func startInstance(ec2HostConfig *config.Ec2HostConfig, instance *ec2.Instance, svc *ec2.EC2) error {
	startCalled := false
	instanceId := *instance.InstanceId

	// wait until the state is anything but "pending"
statePoll:
	for {
		state, err := getInstanceState(instanceId, svc)
		if err != nil {
			return err
		}

		log.Printf("Instance %s is in state %s", instanceId, state)
		switch state {
		case "pending", "shutting-down", "stopping":
			// for any of the transient states, just wait
			time.Sleep(time.Second / 2)

		case "running":
			// running is the state we want to get to
			break statePoll

		case "stopped":
			log.Printf("starting instance %s", instanceId)
			if startCalled {
				return fmt.Errorf("instance %s did not enter the running state", instanceId)
			}
			// start a stopped instance
			params := &ec2.StartInstancesInput{
				InstanceIds: []*string{aws.String(instanceId)},
			}
			_, err := svc.StartInstances(params)
			if err != nil {
				return err
			}
			startCalled = true

		case "terminated":
			return fmt.Errorf("Instance is terminated")
		}
	}

	// wait for SSH port to be open, too
	for {
		// re-search for the instance, since it probably didn't have a public ip address
		// when it was disconnected -- TODO refactor
		if instance.PublicIpAddress == nil {
			var err error
			instance, err = findInstance(ec2HostConfig, svc)
			if err != nil {
				return fmt.Errorf("while searcihng for running instance: %s", err)

		conn, err := net.Dial("tcp", fmt.Sprintf("%s:22", *instance.PublicIpAddress))
		if err != nil {
			log.Printf("connecting to port 22: %s; retrying", err)
			time.Sleep(time.Second / 2)
		} else {
			conn.Close()
			break
