K3s: the most downloaded Kubernetes distribution
K3s is a CNCF sandbox project that delivers a lightweight yet powerful certified Kubernetes distribution. When used with Rancher Prime, K3s is ideal for running production workloads with reliability for years
Up to 5 years of support for k3s with Rancher Prime
With Rancher Prime, K3s users can manage 1000's of edge-based clusters using GitOps-driven Continuous Delivery. Obtain up to 5 years of enterprise support for k3s with Rancher Prime.
K3s was originally a Rancher Labs project. In June 2020, K3s was donated to the CNCF as a testament to the company’s commitment to the open source community. SUSE is now a major contributor to the project.
K3s is packaged as a single < 40MB binary that reduces the dependencies and steps needed to install, run and auto-update a production Kubernetes cluster.
Both ARM64 and ARMv7 are supported with binaries and multi arch images available for both. K3s works great from something as small as Raspberry Pi to an AWS a1.4x large 32gb server.
"SUSE solutions enable our OpenSpace customers to deploy new satellite services in minutes instead of weeks, or even months."
