We will IPAM functionality in this version separate from the OVN, and give it to other CNI network plug-in provides the ability to cluster level IPAM functionality. CNI now other plug-ins, such as macvlan, host-device, vlan-peer networks can strengthen their abilities through the use of IP subnets and fixed function Kube-OVN in. You can refer to multiple network cards supporting documentation to learn how to use.
This version will OVN upgrade to 20.03, OVS upgrade to 2.13, and joined the compiler optimization for x86 architecture increases the performance control plane and data plane. With the new version at the same time the ability of the OVN, we achieved hairpin load balancer.
To further simplify the installation process, starting from this version we provide one-click installation deployment scripts, users can quickly build up a high-availability, production-ready Kubernetes network system. Refer to the one-click installation documentation for installation deployment
