Open Networking Summit Europe 2018

Kubernetes has become the de facto tool in container orchestration thus it will be the foundation of enterprise DevOps. However, recent surveys conducted by the Cloud Native Compute Foundation show that majority of the end users face challenges with networking during deploying Kubernetes.
This talk will have a short overview on the basics of Kubernetes networking: how does the Container Networking Interface work, how do the popular network plugins provide connectivity between PODs, and what is the role of Kube Proxy.
Then I will present how anyone can solve the Kubernetes networking problem solely relying on Open vSwitch and the OpenFlow protocol. Such solution has the benefit that it can be integrated into higher level SDN frameworks using ONOS, ODL or Tungsten, while it does not rely on any Linux kernel modules thus it is compatible with full line rate user-space networking with DPDK.
