# Getting Started with kOps on Hetzner Cloud
|
|
|
|
**WARNING**: Hetzner Cloud support on kOps is currently in **alpha**, meaning it is subject to change, so please use with caution.
|
|
The original issue ticket is [#8983](https://github.com/kubernetes/kops/issues/8983).
|
|
|
|
## Requirements
|
|
* kOps version >= 1.24
|
|
* kubectl version >= 1.23
|
|
* Hetzner Cloud [account](https://accounts.hetzner.com/login)
|
|
* Hetzner Cloud [token](https://docs.hetzner.cloud/#authentication)
|
|
* SSH public and private keys
|
|
* S3 compatible object storage (like [MinIO](https://docs.min.io/minio/baremetal/security/minio-identity-management/user-management.html))
|
|
|
|
## Environment Variables
|
|
|
|
It is important to set the following environment variables:
|
|
```bash
|
|
export KOPS_FEATURE_FLAGS=Hetzner
|
|
export HCLOUD_TOKEN=<token>
|
|
export S3_ENDPOINT=<endpoint>
|
|
export S3_ACCESS_KEY_ID=<acces-key>
|
|
export S3_SECRET_ACCESS_KEY=<secret-key>
|
|
export KOPS_STATE_STORE=s3://<bucket-name>
|
|
```
|
|
|
|
## Creating a Single Master Cluster
|
|
|
|
In the following examples, `example.k8s.local` is a [gossip-based DNS ](../gossip.md) cluster name.
|
|
|
|
```bash
|
|
# create a ubuntu 20.04 + calico cluster in fsn1
|
|
kops create cluster --name=my-cluster.example.k8s.local \
|
|
--ssh-public-key=~/.ssh/id_rsa.pub --cloud=hetzner --zones=fsn1 \
|
|
--image=ubuntu-20.04 --networking=calico --network-cidr=10.10.0.0/16
|
|
kops update cluster my-cluster.example.k8s.local --yes
|
|
|
|
# create a ubuntu 20.04 + calico cluster in fsn1 with CPU optimized servers
|
|
kops create cluster --name=my-cluster.example.k8s.local \
|
|
--ssh-public-key=~/.ssh/id_rsa.pub --cloud=hetzner --zones=fsn1 \
|
|
--image=ubuntu-20.04 --networking=calico --network-cidr=10.10.0.0/16 \
|
|
--node-size cpx31
|
|
kops update cluster my-cluster.example.k8s.local --yes
|
|
|
|
# delete a cluster
|
|
kops delete cluster --name=my-cluster.example.k8s.local --yes
|
|
|
|
# export kubecfg
|
|
# See https://kops.sigs.k8s.io/cli/kops_export_kubeconfig/#examples.
|
|
|
|
# update a cluster
|
|
# See https://kops.sigs.k8s.io/operations/updates_and_upgrades/#manual-update.
|
|
```
|
|
|
|
## Features Still in Development
|
|
|
|
kOps for Hetzner Cloud currently does not support the following features:
|
|
|
|
* Cluster validation
|
|
* Rolling updates
|
|
* Autoscaling using [Cluster Autoscaler](https://github.com/hetznercloud/autoscaler)
|
|
* Volumes using the [CSI Driver](https://github.com/hetznercloud/csi-driver)
|
|
* [Terraform](https://github.com/hetznercloud/terraform-provider-hcloud) support
|
|
* Multiple SSH keys
|
|
|
|
