Lightweight Kubernetes Distribution

A highly available, certified Kubernetes distribution designed for production workloads in resource-constrained, remote, or IoT environments, packaged as a single binary that eliminates the complexity of traditional Kubernetes installations. The entire distribution weighs approximately 70 megabytes including all dependencies, making it small enough to run on devices with as little as 512 megabytes of RAM while maintaining full Kubernetes API compatibility. Built by Rancher Labs, now part of SUSE, the distribution replaces heavy dependencies with lightweight alternatives, using SQLite as the default datastore instead of etcd, containerd as the runtime instead of Docker, and a single process manager for all Kubernetes components. Despite its small footprint, the distribution supports high availability through a multi-server cluster mode with an embedded distributed database, external datastore connectivity for MySQL and PostgreSQL, and automatic leader election. The single-binary architecture simplifies deployment to edge devices, ARM-based single-board computers, cloud instances, and bare metal servers, with installation requiring only a single command. Built-in features include automatic TLS certificate management, built-in local storage provisioning, service load balancing through Klipper, Helm controller for package management, and a built-in container registry. The distribution is CNCF certified, meaning it passes the same conformance tests as full Kubernetes distributions, ensuring that applications deployed on standard Kubernetes run identically. Common use cases include edge computing deployments, IoT device orchestration, CI pipelines, development environments, and production clusters where operational simplicity and minimal resource consumption are priorities. The embedded ingress controller and service mesh options provide production-grade networking without additional installation steps.
