There are several components involved in implementing networking in a Kubernetes cluster. This lesson provides an overview of what we have already done in our cluster in order to implement networking, as well as the remaining steps that will be performed to implement a virtual cluster network. It also introduces Weave Net, the networking solution that we will use in this course. After completing this lesson, you will have an understanding of the networking configuration that we are implementing in our cluster, and you will be ready to install Weave Net.
