Kubermatic KubeOne

Kubermatic KubeOne automates cluster operations on all your cloud, on-prem, edge, and IoT environments. KubeOne can install high-available (HA) master clusters as well single master clusters.

Getting Started

All user documentation for the latest stable version is available at the KubeOne docs website.

Information about the support policy (natively-supported providers, supported Kubernetes versions, and supported operating systems) can be found in the Compatibility document.

For a quick start, you should check the following documents:

• Architecture to get familiar with the concepts of KubeOne.
• Getting KubeOne to download and install KubeOne locally.
• Provisioning to provision the Kubernetes cluster.

Installing KubeOne

The fastest way to install KubeOne is to use the installation script:

curl -sfL get.kubeone.io | sh

The installation script downloads the release archive from GitHub, installs the KubeOne binary in your /usr/local/bin directory, and unpacks the example Terraform configs, addons, and helper scripts in your current working directory.

For other installation methods, check the Getting KubeOne guide on our documentation website.
