There’s a reason why the kubernetes project is the current crown jewel of the cloud native community, with attendance at Kubecon 2017 in Austin nearly four times that of last year’s conference in Seattle and seemingly every major enterprise vendor perched behind a booth in the exhibit hall eager to help attendees take advantage of the platform. The reason is that the advantages are significant, especially in those areas that matter most to developers and system engineers: application reliability, observe-ability, control-ability and life-cycle management. If Docker built the engine of the container revolution then it was kubernetes that supplied the chassis and got it up to highway speed.

Understanding kubernetes networking: ingress
In the first post of this series I described the network that enables pods to connect to each other across nodes in a kubernetes cluster. The second focused on how the service network provides load balancing for pods so that clients inside the cluster can communicate with them reliably. For this third and final installment I want to build on those concepts to show how clients outside the cluster can connect to pods using the same service network. For various reasons this will likely be the most involved of the three, and the concepts introduced in parts one and two are prerequisites to getting much value out of what follows.
