Explore a practical Kubernetes hard multi-tenancy solution in this conference talk by Fei Guo from Alibaba. Dive into the concept of Virtual Cluster, an innovative approach to address multi-tenancy challenges in Kubernetes production environments. Learn how this solution overcomes limitations of conventional namespace-based multi-tenancy, such as lack of tenant-aware flow control in APIServer and restrictions on installing customized CRDs. Discover how Virtual Cluster assigns dedicated Kubernetes control planes to each tenant while sharing a super master, all implemented using Custom Resource Definitions (CRDs). Gain insights into this open-source solution that offers a fresh perspective on resolving multi-tenancy issues in Kubernetes deployments.
