# Kubernetes image for Hetzner Cloud
This [Packer](https://www.packer.io) project creates an image to spin up [Kubernetes](https://kubernetes.io) clusters with [kubeadm](https://kubernetes.io/docs/reference/setup-tools/kubeadm) or [Kubernetes Cluster API](https://cluster-api.sigs.k8s.io) on [Hetzner Cloud](https://www.hetzner.com/cloud).
## Features
- All requirements to setup a Kubernetes cluster with `kubeadm`
- [containerd](https://containerd.io) as container runtime
- AMD64 and ARM64 support
- IPv4/IPv6 dual-stack networking support
- Integrity of downloaded files verified with `sha256sum`
- Images used by `kubeadm` pulled as building step
## Getting started
Set `HCLOUD_TOKEN` environment variable or `token` variable and run `packer build`, for example:
```shell
export HCLOUD_TOKEN=xxxx
packer build .
```
To build an ARM64 image, set `server_type` variable to `cax11`:
```shell
export HCLOUD_TOKEN=xxxx
packer build -var server_type=cax11 .
```
