Deep dive 3 into Docker Overlay networks – Part 3

Introduction In part 1 of this blog post we have seen how Docker creates a dedicated namespace for the overlay and connect the containers to this namespace. In part 2 we have looked in details at how Docker uses VXLAN to tunnel traffic between the hosts in the overlay. In this third post, we will see how we can create our own overlay ...
