Ultra-lightweight, single-node Kubernetes optimized for IoT and edge

Features

• Ultra-lightweight, single-node Kubernetes distribution for resource-constrained environments such as IoT, embedded, and edge devices
• Installed and operated as a single binary with all major components built in. Minimal external dependencies
  • Uses SQLite instead of etcd as the default storage via Kine
  • All essential components, such as containerd & runc as the container runtime and CoreDNS for DNS, are packaged into a single launcher
• Lock-free, multi-process architecture that integrates various components within a single process
• Removes the Kubernetes Scheduler and replaces it with a custom Webhook NodeSetter
• Offline operation support: all features are available without an internet connection
• Differences from other Kubernetes distributions
  • Unlike distributed/lightweight distributions for the FOG layer such as K3s and MicroK8s, KubeSolo focuses on edge devices
  • No cluster features, no etcd, supports only single-node operation
  • All deployments, patches, and releases quickly follow upstream as a fork based on K3s
• Runs on all Linux distributions (ARM, ARM64, x86_64)
