OpenELB 2022 Annual Review
This is a Kubernetes ToC Annual Review for the OpenELB project for 2022.
Table of Contents
Background
OpenELB is an open-source load balancer implementation designed for exposing the LoadBalancer type of Kubernetes services in bare metal, edge, and virtualization environments.
In cloud-based Kubernetes clusters, Services are usually exposed by using load balancers provided by cloud vendors. However, cloud-based load balancers are unavailable in bare-metal or on-premise environments. OpenELB allows users to create LoadBalancer Services in bare-metal, egde, and virtualization environments for external access, and provides the same user experience as cloud-based load balancers.

Project Goals & Update
Our current goal is to improve product functions, expand users, and discover contributors.
Project Features：
- Refactor openelb so that it can be better used in more complex environments.
- Support for compatibility with more cni plugins.
- Support for more routing protocols.
- Improve openelb console to make user operations more convenient.
- Solve the single point of failure of layer2 mode to achieve failover.
- Support eip to bind different namespaces.
- Improve openelb monitoring metrics and support importing to grafana.
Docs：
- Improve the docs more in "How it works", in addition to "How to use".
- Publish some related technical blogs.
Community：
- keep being contributor friendly and open to discuss new feature requests and responsive to contributors willing to help.
In 2022 we've shipped features like:
- Support user to configure custom container image
- Add some simple monitoring metrics
- Support vip mode
- Support to assign ip by configuring default EIP
CNCF Membership
In 2022 we participated in the lfx-mentorship event and achieved certain results. Two active contributors participated in the development, but then had to suspend maintenance and contributions due to their academic pressure.
Incubation
OpenELB is not yet ready for incubation. At this stage, the documentation of openelb is relatively missing and relatively incomplete. The community is not very active, and there are fewer users. Therefore, we are actively attracting more open source contributors to join, and promoting it to let more users know and use it.
