In this chapter, we have looked at three different network drivers, all three of which add quite powerful functionality to your basic Docker installation. These, along with the volume drivers, really extend Docker to the point where you can run large fault-tolerant clusters of containers.

Personally, when I first installed Weave and started to communicate with containers across different Docker hosts in different hosting providers so easily, I was absolutely blown away.

In the next chapter, we will look at how you should approach to creating your own extension.
