2. Introducing k3s
• Lightweight certified Kubernetes distro
• Built for production operations
• 40MB binary, 250MB memory consumption
• Single process w/ integrated Kubernetes master,
Kubelet, and containerd
• SQLite in addition to etcd
• Simultaneously released for x86_64, ARM64, and
ARMv7
• Open source project, not yet a Rancher product

3. To build k3s we removed unnecessary code and
made a few enhancements

4. How k3s works

5. K3s use cases
1. Edge computing
2. IOT Gateway
3. CI environments
4. Single-App Clusters

6. K3sup

7. k3sup is a light-weight utility to get from zero to KUBECONFIG with k3s on any
local or remote VM. All you need is ssh access and the k3sup binary to
get kubectl access immediately.
The tool is written in Go and is cross-compiled for Linux, Windows, MacOS and
even on Raspberry Pi.
Made for Developers
What is K3sup ?

8. Architecture

9. Benefits
Uses:
•Bootstrap Kubernetes with k3s onto any VM - either
manually, during CI or through cloudinit
•Get from zero to kubectl with k3s on Raspberry Pi (RPi),
VMs, most cloud vendors
•Fetch a working KUBECONFIG from an
existing k3s cluster
•Join nodes into an existing k3s cluster with k3sup join
