The following steps will quickly deploy a Rancher server on Hetzner Cloud in a single-node K3s Kubernetes cluster, with a single-node downstream Kubernetes cluster attached.
The intent of these guides is to quickly launch a sandbox that you can use to evaluate Rancher. These guides are not intended for production environments. For comprehensive setup instructions, see Installation.
Deploying to Hetzner Cloud will incur charges.
- Hetzner Cloud Account: You will require an account on Hetzner as this is where the server and cluster will run.
- Hetzner API Access Key: Use these instructions to create a Hetzner Cloud API Key if you don't have one.
- Terraform: Used to provision the server and cluster to Hetzner.
Clone Rancher Quickstart to a folder using
git clone https://github.com/rancher/quickstart.
Go into the Hetzner folder containing the Terraform files by executing
terraform.tfvarsand customize the following variables:
hcloud_token- Hetzner API access key
rancher_server_admin_password- Admin password for created Rancher server (minimum 12 characters)
prefix- Prefix for all created resources
instance_type- Instance type, minimum required is
hcloud_location- Hetzner Cloud location, choose the closest instead of the default (
To initiate the creation of the environment, run
terraform apply --auto-approve. Then wait for output similar to the following:
Apply complete! Resources: 15 added, 0 changed, 0 destroyed.
rancher_node_ip = xx.xx.xx.xx
rancher_server_url = https://rancher.xx.xx.xx.xx.sslip.io
workload_node_ip = yy.yy.yy.yy

ssh to the Rancher Server using the

Two Kubernetes clusters are deployed into your Hetzner account, one running Rancher Server and the other ready for experimentation deployments. Please note that while this setup is a great way to explore Rancher functionality, a production setup should follow our high availability setup guidelines. SSH keys for the VMs are auto-generated and stored in the module directory.
Use Rancher to create a deployment. For more information, see Creating Deployments.
Destroying the Environment
terraform destroy --auto-approve.
Wait for confirmation that all resources have been destroyed.
