v1.1.0 -- 2020/04/07
In this version, we refactor IPAM to separate IP allocation logical from OVN. On top of that we provide a general cluster wide IPAM utility for other CNI plugins. Now other CNI plugins like macvlan/host-device/vlan etc can take advantage of subnet and static ip allocation functions in Kube-OVN.Please check this document to see how we combine Kube-OVN and Multus-CNI to provide multi-nic container network.
This version also update OVN to 20.03 and OVS to 2.13 with some x86 related optimization, which increase the control plan data plan performance and we finally support hairpin LB now.
This version also simplify the installation steps by merge all components into one image and add a new one-click installation script to help users setup a high-available, production-ready Kube-OVN container network. Please look the installation guide
