Rancher K3s

K3s is a lightweight, certified Kubernetes distribution originally developed by Rancher Labs and now maintained as a CNCF Sandbox Project. Designed specifically for resource-constrained environments, K3s delivers a fully compliant Kubernetes experience packaged as a single binary under 70MB. This streamlined approach dramatically reduces the complexity typically associated with Kubernetes deployment and management. The platform excels in edge computing, IoT deployments, CI/CD pipelines, and development environments where traditional Kubernetes distributions would be too resource-intensive. K3s supports both ARM64 and ARMv7 architectures, making it versatile enough to run on devices as small as a Raspberry Pi or scale up to powerful cloud servers. With its focus on security, simplicity, and high availability, K3s enables organizations to bring production-ready Kubernetes to previously impractical locations including air-gapped setups and remote, unattended installations.
