This Packer project creates an image to spin up Kubernetes clusters with kubeadm or Kubernetes Cluster API on Hetzner Cloud.
- All requirements to setup a Kubernetes cluster with
kubeadm - containerd as container runtime
- AMD64 and ARM64 support
- IPv4/IPv6 dual-stack networking support
- Integrity of downloaded files verified with
sha256sum - Images used by
kubeadmpulled as building step
Set HCLOUD_TOKEN environment variable or token variable and run packer build, for example:
export HCLOUD_TOKEN=xxxx
packer build .To build an ARM64 image, set server_type variable to cax11:
export HCLOUD_TOKEN=xxxx
packer build -var server_type=cax11 .| Name | Description | Default |
