Kettled twice. Extra chewy, extra trustworthy.
Summary
K3k is an open-source tool from Rancher that enables users to create and manage isolated K3s (lightweight Kubernetes) clusters within an existing Kubernetes environment. It supports multi-tenancy, experimentation, and resource isolation by running multiple lightweight clusters on the same physical host. K3k offers two modes: "shared" mode for optimized resource utilization and "virtual" mode for complete isolation with dedicated K3s server pods, providing a full Kubernetes experience without the overhead of managing separate infrastructure.
