k3sup is a lightweight Go CLI tool that bootstraps a K3s Kubernetes cluster on any local or remote VM over SSH, getting you a working KUBECONFIG in under a minute. It supports joining agent nodes, HA multi-master setups, and offers a Pro edition with plan/apply GitOps-style automation.
Use cases
- bootstrap a k3s cluster over ssh
- get a kubeconfig for a remote vm in under a minute
- set up kubernetes on a raspberry pi
- join worker nodes to a k3s cluster
- create a multi-master HA k3s cluster
- quickly provision kubernetes for a homelab
When to choose
- you need a fast, minimal Kubernetes setup on VMs, edge devices, or Raspberry Pis using only SSH access
- you want a simple CLI-driven alternative to heavier installers like kubeadm or Rancher
- you want HA k3s with embedded etcd or external SQL without manual steps
When to avoid
- you need a full-featured Kubernetes distribution with a management UI like Rancher or OpenShift
- you cannot use SSH to reach the target machines
- you require managed Kubernetes from a cloud provider
- you need declarative, GitOps-managed cluster lifecycle out of the box without the Pro edition
