KubeOne

GoDoc Go Report Card

kubeone is a CLI tool and a Go library for installing, managing, and upgrading Kubernetes High-Available (HA) clusters. It can be used on any cloud provider, on-prem or bare-metal cluster.

Project Status

As of v0.6.0, KubeOne is in the beta phase. Check out the Backwards Compatibility Policy for more details on backwards compatibility, KubeOne versioning, and maturity of each KubeOne component.

Versions earlier than v0.6.0 are considered alpha and it's strongly advised to upgrade to the v0.6.0 or newer as soon as possible.

KubeOne in Action

Features

  • Supports Kubernetes 1.13+ High-Available (HA) clusters
  • Uses kubeadm to provision clusters
  • Comes with a straightforward and easy to use CLI
  • Choice of Linux distributions between Ubuntu, CentOS and CoreOS
  • Integrates with Cluster-API and Kubermatic machine-controller to manage worker nodes
  • Integrates with Terraform for sourcing data about infrastructure and control plane nodes
  • Officially supports AWS, DigitalOcean, GCE, Hetzner, Packet and OpenStack

Installing KubeOne

The easiest way to install KubeOne is using go get:

go get -u github.com/kubermatic/kubeone

However, running of the master branch introduces potential risks as the project is currently in the alpha phase and backwards incompatible changes can be expected.

Alternatively, you can obtain KubeOne via GitHub Releases:

curl -LO https://github.com/kubermatic/kubeone/releases/download/v0.6.2/kubeone_0.6.2_linux_amd64.zip
unzip kubeone_0.6.2_linux_amd64.zip
sudo mv kubeone /usr/local/bin

If you already have KubeOne repository cloned, you can use Makefile to install KubeOne.

make install

Kubernetes Versions Compatibility

Each KubeOne version is supposed to support and work with a set of Kubernetes minor versions. We're targeting to support at least 3 minor Kubernetes versions, however for early KubeOne releases we're supporting only one or two minor versions.

New KubeOne release will be done for each minor Kubernetes version. Usually, a new release is targeted 2-3 weeks after Kubernetes release, depending on number of changes needed to support a new version.

In the following table you can find what are supported Kubernetes versions for each KubeOne version. KubeOne versions that are crossed out are not supported. It's highly recommended to use the latest version whenever possible.

KubeOne version 1.14 1.13 1.12 Supported providers
v0.6.2 + + - AWS, DigitalOcean, GCE, Hetzner, Packet, OpenStack
v0.6.1 + + - AWS, DigitalOcean, GCE, Hetzner, Packet, OpenStack
v0.6.0 + + - AWS, DigitalOcean, GCE, Hetzner, Packet, OpenStack
v0.5.0 + + - AWS, DigitalOcean, GCE, Hetzner, OpenStack
v0.4.1 - + - AWS, DigitalOcean, Hetzner, OpenStack
v0.4.0 - + - AWS, DigitalOcean, Hetzner, OpenStack
v0.3.0 - + - AWS, DigitalOcean, Hetzner, OpenStack

Note: Versions v0.2.0 and v0.1.0-beta0 don't support upgrading to the newer Kubernetes version.

Getting Started

We have a getting started tutorial for each cloud provider we support in our documentation. For example, the following document shows how to get started with KubeOne on AWS.

A cluster is created using the kubeone install command. It takes a KubeOne configuration file and optionally Terraform state used to source information about the infrastructure.

kubeone install config.yaml --tfjson tf.json

To learn more about KubeOne configuration, please run kubeone config print --full.

For advanced use cases and other features, check the KubeOne features document.
