About
K3s is a lightweight, certified Kubernetes distribution packaged as a single binary under 70MB, designed for production workloads in resource-constrained, remote, or IoT environments. It supports x86_64, ARM64, and ARMv7 architectures, making it suitable for devices as small as a Raspberry Pi. Originally developed by Rancher Labs, it is now a CNCF Sandbox Project.
Problem
Running full Kubernetes distributions is too heavy and complex for edge, IoT, and ARM-based environments with limited resources.
For
DevOps engineers and developers deploying Kubernetes on edge, IoT, or resource-constrained environments
How it works
K3s packages a certified Kubernetes distribution into a single binary, stripping out unnecessary components and reducing dependencies so clusters can be installed and run with a single command.
