Installing KubeOne

Downloading a binary from GitHub Releases

The recommended way to obtain KubeOne is to grab the binary from the GitHub Releases page. On the releases page, find the binary for your operating system and architecture and download it or grab the URL and use wget or curl to download the binary.

Version: version of KubeOne
Operating system: linux or darwin for macOS

curl -LO https://github.com/kubermatic/kubeone/releases/download/v<version>/kubeone_<version>_<operating_system>_amd64.zip

Extract the binary to the KubeOne directory. On Linux and macOS, you can use unzip.

unzip kubeone_<version>_<operating_system>_amd64.zip -d kubeone_<version>_<operating_system>_amd64

Move the kubeone binary to your path, so you can easily invoke it from your terminal.

sudo mv kubeone_<version>_<operating_system>_amd64/kubeone /usr/local/bin

For a quick way to install the lastest version of KubeOne, use the following commands:

VERSION=$(curl -w '%{url_effective}' -I -L -s -S https://github.com/kubermatic/kubeone/releases/latest -o /dev/null | sed -e 's|.*/v||')
curl -LO "https://github.com/kubermatic/kubeone/releases/download/v${VERSION}/kubeone_${VERSION}_${OS}_amd64.zip"
unzip kubeone_${VERSION}_${OS}_amd64.zip -d kubeone_${VERSION}_${OS}_amd64
sudo mv kubeone_${VERSION}_${OS}_amd64/kubeone /usr/local/bin

Building KubeOne

The alternative way to install KubeOne is using go get.

To get latest stable release:

GO111MODULE=on go get github.com/kubermatic/kubeone

To get latest beta release (for example v0.11.0-beta.0 tag):

GO111MODULE=on go get github.com/kubermatic/kubeone@v0.11.0-beta.0

While running of the master branch is a great way to peak at and test the new features before they are released, note that master branch can break at any time or may contain bugs. Official releases are considered stable and recommended for the production usage.

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

make install

Using package managers

Support for packages managers is still work in progress and expected to be finished for one of the upcoming release. For details about the progress follow the issue #471

Arch Linux

We have a package in the AUR. Use your favorite method to build it on your system, for example by using aurutils:

aur sync kubeone && pacman -S kubeone

Shell completion and generating documentation

KubeOne comes with commands for generating scripts for the shell completion and for the documentation in format of man pages and more.

To activate completions for bash (or zsh), run or put this command into your .bashrc file:

. <(kubeone completion bash)

To put changes in the effect, source your .bashrc file.

source ~/.bashrc

To generate documentation (man pages for example, more available), run:

kubeone document man -o /tmp/man

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.

Since some Terraform releases introduces incompatibilities to previuos versions, only a specific version range is supported with each KubeOne release.

In the following table you can find what are supported Kubernetes and Terraform 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 1.18 1.17 1.16 1.15 1.14 Terraform Supported providers
v0.11.0+ + + + + - v0.12+ AWS, DigitalOcean, GCE, Hetzner, Packet, OpenStack, vSphere, Azure
v0.10.0+ - - + + + v0.12+ AWS, DigitalOcean, GCE, Hetzner, Packet, OpenStack, vSphere, Azure

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. You may also use our Ansible roles to create the configuration file.

kubeone install -m config.yaml --tfjson tf.json

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