2022 Kube-OVN Open Source Community Annual Report

Thanks to all the community partners for accompanying Kube-OVN to go through another year of rapid development. With the wide application of Kubernetes technology, the usage rate of CNI network plug-ins is gradually increasing, and the Kube-OVN community is also growing. Let us follow this article and walk into Kube-OVN's 2022.

Continuous optimization of product functions

2022 is a year for Kube-OVN to lay a solid foundation and consolidate its advantages, and complete the upgrade from 1.10 to 1.11.

In the two major versions of this year, Kube-OVN has greatly enhanced its functions and performance as always, including the intercommunication between Overlay and Underlay, the nesting of Underlay in k8s on k8s environment, the support of LoadBalancer type Service, and the support of SR-IOV Network Operator , internal load balancing under custom VPC, DNS under custom VPC, etc.

In addition, Kube-OVN continues to improve stability and ease of use, reconstructs the test system, supplements a large number of tests, and continuously upgrades existing problems, in order to become the highest performance and most usable open source container network plug-in. keep trying!

"If you miss the rich network capabilities in the SDN field but are struggling to find it in the cloud-native field, then Kube-OVN will be your best choice." In addition to product functions, a special topic on advanced functions is also introduced to introduce the working principle and usage path of Kube-OVN advanced functions one by one, helping you quickly realize the advancement of cloud-native networks!

Landing practice and adding cases

With the further popularization of the use of CNI network plug-ins, the high-performance CNI network plug-in Kube-OVN has blossomed in more industries and more scenarios.

As CNCF's first sandbox container network project, with the joint efforts of community partners from companies such as China Telecom, China Unicom, Intel, NVIDIA, F5, ByteDance, Tianyi Cloud, Inspur, Yealink, etc., the functions and performance have been continuously enhanced , stability and ease of use, solve cloud-native network problems for users, and become the cloud-native network solution recommended by technical teams of many large companies.

Application scenarios are constantly enriched

With the joint efforts of community members, the application scenarios of Kube-OVN have been continuously enriched and improved in the past year. As cloud-native technology sinks from the application side to the data center and infrastructure, more and more enterprises begin to use Kubernetes and KubeVirt to run virtualized workloads, achieving simultaneous management of virtual machines and containers on a unified control plane. Since Kube-OVN uses OVN/OVS, which is widely used in traditional virtualized networks, it has attracted the attention of many KubeVirt users after open source. Some cutting-edge KubeVirt users have further improved the network capabilities of Kube-OVN according to their own usage scenarios. , including fixed address, multi-tenant network, SR-IOV and OVS-DPDK functions, which greatly enhance KubeVirt's cloud-native virtualization experience.

At the same time, the F5 CES solution also integrates Kube-OVN, which solves the challenge of outbound traffic policy control in highly dynamic IP scenarios in a k8s native way, and solves the problem of enterprise security, network, platform, and application operation through a hierarchical design. Multi-role cooperation between dimension departments helps users better manage k8s internal container export strategies.

The size of the community continues to grow

In 2022, the operation of the Kube-OVN open source community will continue to improve, attracting the attention of more and more IT practitioners. The range of users continues to expand. In addition to the previous network engineers, it has also gained the support of architects, development engineers, operation and maintenance engineers, security engineers and other technical leaders.

According to incomplete statistics, the number of Stars of Kube-OVN on Github has increased from 1.1k last year to 1.6k+, Forks have increased from 300 last year to nearly 400, Commits have achieved a breakthrough from 2000 to 3000+, The number of image downloads has exceeded 2 million, an increase of about 400,000 compared with last year. Community contributors have increased by 25%, the number of PR contribution units has doubled, the number of community users has increased by 92%, and community members have exceeded 1.5k, an increase of 50%...

Finally, I hope that more people who pay attention to the container network can join the Kube-OVN community, strengthen the power of K8s open source, and jointly create better CNI plug-ins to lead the development of the container network together!

About Kube-OVN

Kube-OVN is an enterprise-level cloud-native Kubernetes container network orchestration system independently developed by Lingqueyun. It translates the mature network functions in the OpenStack field to Kubernetes, which greatly enhances the security and operability of the Kubernetes container network. Security, manageability, and performance bring unique value to the implementation of the Kubernetes ecosystem.

At the beginning of 2021, Kube-OVN became the first open source CNI network project hosted by CNCF in the world, and it was also the first time that a Chinese container company successfully contributed an independently designed and developed project to the CNCF Foundation. At the same time, it is also a star project under the Mulan community one.
