Panel Discussion: Containers and Networking: A Symbiotic Relationship
summary
Covers how container networking actually works: CNI from CoreOS and the Docker CNM plugin model, host virtual switches like OVN/Open vSwitch, and efforts to bridge Kubernetes to OpenStack so VLAN/VXLAN can interoperate. Claims: modular interfaces enable portability between bare metal, VMs and cloud; Windows support landed in Docker 17.06; Envoy and service mesh are proposed for non‑connectivity services. Concrete challenges: NUMA pinning, kernel bypass, double encapsulation, and the need for debuggable visibility and orchestration-aware scheduling.
