hetzner-kube: fast and easy setup of kubernetes clusters on Hetzner Cloud
This is my very first tool written in Go.
How to install
Get the binary from releases page
hetzner-kube is written in Go. To install Go please follow the instructions on its homepage.
To get and build
hetzner-kube from source run this command:
$ go get -u github.com/xetys/hetzner-kube
The project source will now be in your
$GOPATH directory (
$GOPATH/src/github.com/xetys/hetzner-kube) and the binary will be in
If you want to build it yourself later, you can change into the source directory and run
go build or
To load completion for bash env run
. <(hetzner-kube completion)
To configure your bash shell to load completions for each session add to your
# ~/.bashrc or ~/.profile . <(hetzner-kube completion)
Or you can add it to your
# On linux hetzner-kube completion > /etc/bash_completion.d/hetzner-kube # On OSX with completion installed via brew (`brew intall bash-completion`) hetzner-kube completion > /usr/local/etc/bash_completion.d/hetzner-kube
In your Hetzner Console generate an API token and
$ hetzner-kube context add my-project Token: <PASTE-TOKEN-HERE>
Then you need to add an SSH key:
$ hetzner-kube ssh-key add -n my-key
This assumes, you already have a SSH keypair
And finally, you can create a cluster by running:
$ hetzner-kube cluster create --name my-cluster --ssh-key my-key
This will provision a brand new kubernetes cluster in latest version!
For a full list of options that can be passed to the
cluster create command, see the Cluster Create Guide for more information.
You can build high available clusters with hetzner-kube. Read the High availability Guide for further information.
You can install some addons to your cluster using the
cluster addon sub-command. Get a list of addons using:
$ hetzner-kube cluster addon list
contributing new addons
You want to add some cool stuff to hetzner-kube? It's quite easy! Learn how to add new addons in the Developing Addons documentation.
If you like to run some scripts or install some additional packages while provisioning new servers, you can use cloud-init
$ hetzner-kube cluster create --name my-cluster --nodes 3 --ssh-key my-key --cloud-init <PATH-TO-FILE>
An example file to make all nodes ansible ready. The comment on the first line is important:
#cloud-config package_update: true packages: - python
