Your Kubernetes Cluster is
One Command Away.

Kubesman gives you a guided web UI to deploy and manage RKE2 Kubernetes clusters – powered by Ansible, delivered as a single Docker container.

How It Works

Four Steps to a Running Cluster

1

Install

One curl command. A Docker container starts automatically with a systemd service.

2

Configure

Open localhost:7373 on browser. Walk through the simple guided configuration wizard.

3

Deploy

Watch real-time Ansible output stream to you. Your cluster is ready in minutes.

4

Maintain

Add or remove worker nodes, upgrade RKE2 versions, and monitor cluster health – all from the same web interface.

Features

Everything You Need to Ship Clusters

Built for DevOps engineers and developers who need the power of Kubernetes.

Step-by-Step Wizard

Guided 7-step configuration: nodes, SSH credentials, CNI networking, ingress controllers, persistent storage, labels/taints, and cluster settings.

Real-Time Deploy Logs

WebSocket-streamed Ansible output directly in your browser. Watch every task, play, and role execute in real time – no SSH session needed.

Multiple CNI Options

Choose from Cilium, Calico, Canal (bundled default), or Flannel. Each plugin comes with per-plugin advanced settings you can tune.

Ingress & TLS

NGINX Ingress Controller or Gateway API – your choice. Optional cert-manager integration for automated TLS certificate management.

Persistent Storage

One-click Longhorn setup with configurable replica counts and data paths. Cloud-native distributed storage for your bare-metal cluster.

Cluster Dashboard

Monitor node status, cluster health, and configuration details after deployment. Your cluster at a glance, right from the browser.

Node Management

Add or remove worker nodes post-deploy. Upgrade RKE2 versions across your cluster with a guided workflow – no manual Ansible runs.

Config Validation

Validate your entire configuration before deploying. Catch SSH connectivity issues, port conflicts, and misconfigurations early.
