A common understanding of terms like catalog, add-ons, hub-and-spoke, and push vs pull models is established for the discussion.
Building an internal developer platform is complex and expensive due to the vast CNCF landscape and duplicated effort across teams.
Kubera is an open-source framework and CLI tool designed to bootstrap and manage tailored Kubernetes platforms using modular components.
The framework uses a central hub for management and distributed spokes for workloads, enabling multi-tenancy and centralized control via GitOps.
A live demonstration shows how to use the Kubera CLI to initialize a configuration file and bootstrap a central hub cluster from scratch.
The demo continues by showing how to connect spoke clusters (vClusters) to the hub and deploy add-ons to them using a label-based system.
Load testing reveals that a single Argo CD instance struggles to manage a large number of clusters and objects, highlighting significant memory consumption issues.
Sveltus, an add-on controller, is introduced to complement Argo CD, drastically reducing memory usage and enabling management of thousands of clusters from a single hub.
The transition from an inner-source to a public open-source project involves non-technical challenges like legal issues, community building, and treating the project like a product.
