Rancher Releases K3k Tool for Running Kubernetes Clusters
Original: K3k: Kubernetes in Kubernetes
Why This Matters
Enables cost-effective Kubernetes multi-tenancy and testing environments
Rancher has released K3k, an open-source tool that allows users to create and manage isolated K3s clusters within existing Kubernetes environments. The tool offers both shared and virtual modes for multi-tenancy and resource isolation.
K3k (Kubernetes in Kubernetes) is a new tool from Rancher that enables running multiple lightweight Kubernetes clusters on the same physical host infrastructure. The tool supports two operational modes: 'shared' mode for optimized resource utilization and 'virtual' mode providing complete isolation with dedicated K3s server pods. K3k aims to reduce infrastructure costs while enabling efficient multi-tenancy, streamlined experimentation, and robust resource isolation. The project is available on GitHub under Apache-2.0 license and includes CLI tools, charts, documentation, and examples for deployment and management.
