Explore a French-language conference presentation from OpenInfra Day France 2024 that delves into managing OpenStack infrastructures and Kubernetes clusters through GitOps using Hosted Control Plane on Kubernetes (HPC). Learn about two powerful open-source solutions - Clastix Kamaji and k0smotron - and discover how they integrate with Cluster API to enable efficient management of Kubernetes infrastructure. Understand the architecture of hosted control planes, where control plane components operate separately from worker nodes for enhanced scalability and manageability in multi-cluster environments. Gain insights from speaker Hervé Leclerc of ALTER WAY on implementing declarative APIs and tooling for simplified provisioning, upgrading, and operating multiple Kubernetes clusters on OpenStack, enabling true hybrid deployments across different cloud providers.
