Weave Net (Weave for short) is a third-party network solution for Docker. Early on, it provided users additional network functionality outside of what Docker natively offered. For instance, Weave provided overlay networks and WeaveDNS before Docker began supporting user-defined overlay networks and embedded DNS. However, with the more recent releases, Docker has started to gain feature parity from a network perspective with Weave. That being said, Weave still has a lot to offer and is an interesting example of how a third-party tool can interact with Docker to provide container networking. In this chapter, we'll walk through the basics of installing and configuring Weave to work with Docker as well as describe some of Weaves functionality from a network perspective. While we'll spend some time demonstrating some of the features of Weave this is not intended to be a how-to guide for the entire Weave solution. There are many features of Weave that will not be covered in this chapter. I recommend you check out their website for the most up–to-date information on features and functionality (https://www.weave.works/).
