Explore the future of multi-tenancy in Kubernetes with this insightful conference talk from KubeCon + CloudNativeCon Europe 2022. Delve into the concept of virtual clusters as an advanced approach to multi-tenancy, extending beyond traditional namespace-based solutions. Learn how virtual clusters operate by running Kubernetes clusters on top of other Kubernetes clusters, providing isolated control planes for each tenant. Discover the benefits of this approach for complex use cases, such as installing custom CRDs, managing workloads across multiple namespaces, and supporting different versions of the Kubernetes API server. Gain a comprehensive understanding of virtual cluster implementations, their architecture, and real-world applications through detailed explanations and demonstrations. Explore topics including namespace limitations, the vcluster tool, deployment creation, naming conflict resolution, pod networking, and DNS in virtual cluster environments. Perfect for Kubernetes operators, developers, and enthusiasts looking to optimize resource utilization and enhance multi-tenant cluster management.
