示例1: register

// register is used for registration of node with particular dispatcher.
func (d *Dispatcher) register(ctx context.Context, nodeID string, description *api.NodeDescription) (string, error) {
	// prevent register until we're ready to accept it
	if err := d.isRunningLocked(); err != nil {
		return "", err
	}

	if err := d.nodes.CheckRateLimit(nodeID); err != nil {
		return "", err
	}

	// create or update node in store
	// TODO(stevvooe): Validate node specification.
	var node *api.Node
	err := d.store.Update(func(tx store.Tx) error {
		node = store.GetNode(tx, nodeID)
		if node == nil {
			return ErrNodeNotFound
		}

		node.Description = description
		node.Status = api.NodeStatus{
			State: api.NodeStatus_READY,
		}
		return store.UpdateNode(tx, node)

	})
	if err != nil {
		return "", err
	}

	expireFunc := func() {
		nodeStatus := api.NodeStatus{State: api.NodeStatus_DOWN, Message: "heartbeat failure"}
		log.G(ctx).Debugf("heartbeat expiration")
		if err := d.nodeRemove(nodeID, nodeStatus); err != nil {
			log.G(ctx).WithError(err).Errorf("failed deregistering node after heartbeat expiration")
		}
	}

	rn := d.nodes.Add(node, expireFunc)

	// NOTE(stevvooe): We need be a little careful with re-registration. The
	// current implementation just matches the node id and then gives away the
	// sessionID. If we ever want to use sessionID as a secret, which we may
	// want to, this is giving away the keys to the kitchen.
	//
	// The right behavior is going to be informed by identity. Basically, each
	// time a node registers, we invalidate the session and issue a new
	// session, once identity is proven. This will cause misbehaved agents to
	// be kicked when multiple connections are made.
	return rn.SessionID, nil
}
