Kubernot (k0s)

---

Not Kubernetes

Kubernot is an experimental SSH alternative with Kubernetes-like UX, where

• scp becomes kubectl cp
• ssh becomes kubectl exec
• ssh -L becomes kubectl port-forward

The name Kubernot is inspired by many.

It shortens to k0s, mimicking the spelling of k8s, because Kubernot is made to resemble Kubernetes, while not being a distro of it.

The shortened form should be pronounced as "chaos" not "kay-zero-es" in order to distinguish from Mirantis' k0s.

Unlike SSH, Kubernot adopts the client-agent-server model from Kubernetes that allows access to nodes behind a firewall.

	client	agent	server
SSH	ssh	-	sshd
Kubernot	kubectl	knot	kuber
Kubernetes	kubectl	kubelet	kube-apiserver

Kubernot has two major components: kuber and knot:

• Kuber implements a minimal subset of The Kubernetes API, and is therefore compatible with kubectl.

  It is directly modelled after kube-apiserver.

• Knot is the equivalent of kubelet in Kubernetes.

  It runs on targets like Windows / BSD / Android / Chrome (via WASI), since it only deals with processes, sockets and files - no container support is required.

Getting Started

k0s is the multicall binary of Kubernot.

kubectl is also bundled as a subcommand for convenience.

To install it, run:

$ go install k0s.io/cmd/k0s@latest

To start the server, run:

$ k0s kuber

then point kubectl to http://127.0.0.1:8000 and print the version:

$ k0s kubectl -s http://127.0.0.1:8000 version
