Project Summary

Managing your Kubernetes clusters (including public, private, edge, etc) as easily as visiting the Internet

Project Description

Clusternet is an open-source project that helps users manage multiple Kubernetes clusters as easily as 'visiting the Internet' (thus the name 'Clusternet'). It is a general-purpose system for controlling Kubernetes clusters across different environments as if they were running locally.

Project Updates Since Last Review 🌟🌟🌟

• We've released 14 major releases so far, attracting 30+ contributors from Tencent, intel, ByteDance, Ant Group, Kanzhun, Purple Mountain Laboratories, Dmall, KuGou, Futu, WeBank, QQ Music, 37Games, etc.
• This is not a one-person project any more. More contributors participate in our release. For recent releases, 10+ contributors get participated in a release. Another exciting thing is that we've got more new contributors to join with us. Moreover, we have a bi-weekly regular meeting with other contributors from other companies.
• Clusternet gets stars over 1k. More and more people are watching and using this projects. We do receive many requests from other companies, such as CMCC, Kanzhun. They give us great support on moving forward.
• Within Tencent, we're using Clusternet managing hundreds of Kubernetes clusters, with a total of 1 million CPU cores. And this number keeps growing.
• We introduced this project on Open Source Summit Euro 2022 as well, where we shared some updates and performance benchmarks on using Clusternet to manage Kubernetes clusters running at the edge.
• More integrations. We make integrations with other CNCF projects, such as mcs-api, cluster-api, node-feature-discovery, prometheus, kyverno (ongoing), submariner (ongoing), etc. There will be more integrations like these in the next following releases.
• More frameworks. With the help of many contributors, Clusternet gets the capability to work with multiple scheduling scenarios, such as dividing scheduling (static and dynamic), subgroup scheduling. We build multiple frameworks (scheduling framework, predictor framework) to plumb out-of-tree plugins/implementations.

Why CNCF?

By joining CNCF, we want to motivate more innovation and participation from the open-source community. Some significant values joining CNCF could bring to the project are:

• Be vendor-neutral: Clusternet can get a neutral home in CNCF, to facilitate further project development through a more diverse and neutral community.

• Be more aware: leverage CNCF to promote the project and get more users and contributors through official events, mailing lists, blog posts, etc.

We also believe that Clusternet could be an excellent addition to the existing CNCF landscape. Clusternet is based on Kubernetes, and it is a significant attempt to tackle the multi-cluster Kubernetes management challenge.

Benefit to the Landscape

As Kubernetes gets adopted by large organizations, the demand for multi-cloud and multi-cluster have become prominent to offer better scalability, stability, and cost-saving.

Clusternet is built to address these challenges. It provides an easy-to-operate tool that extends (instead of replaces) Kubernetes. Clusternet naturally supports all the native Kubernetes APIs and fits well in the cloud-native ecosystem.

Clusternet is a decent effort to stitch multiple Kubernetes cluster into a single one. Clusternet turns an existing Kubernetes cluster to a multi-cluster control plane, while keeps the original cluster untainted. We've done a lot of work to make that happen. Clusternet adopts a novel approach to solve multi-cluster problems. This is the biggest difference that makes Clusternet outstanding when comparing with other similar projects.

Cloud Native 'Fit'

Multi-cluster management has been an open issue since the early day of the cloud-native movement. Clusternet is based on Kubernetes, and it is a significant attempt to tackle the multi-cluster Kubernetes management challenge.

Cloud Native 'Integration'

Clusternet can be easily integrated with various cloud native projects to build a powerful multi-cluster Kubernetes platform.

• Clusternet provides build-in support for Helm to coordinate Helm Chart applications across multiple clusters.
• Multiple clusters monitoring is straightforward with Prometheus and Grafana. Registered to Clusternet, each cluster obtain its ID and labels following unified naming convention.
• Cross-cluster service mesh can be achieved by integrating with Linkerd, Istio. Submariner can be used to create an overlay network for cross-cluster connection and service discovery.
• In Clusternet, clusters creating by cluster-api will be discovered automatically and registered to parent cluster. Auto-labelling for managed clusters is also available now. By integrating mcs-api, multi-cluster services are discoverable and accessible across clusters with a virtual IP.

Existing CNCF projects can leverage Clusternet to enhance their multi-cluster management capabilities.
