Run Kubernetes in the Hetzner Cloud

Creates a six node kubernetes cluster in a private network in the Hetzner cloud for fun.

Remember, some costs will occur when using the Hetzner Cloud.

Installation

Env

export HCLOUD_TOKEN=your-hetzner-api-token
export TF_VAR_node_admin_ssh_public_key=path-to-your-ssh-pub-key
export PRIV_KEY_PATH=path-to-your-ssh-priv-key

Provisioning

Go into the provisioning dir.

terraform init
terraform apply

Installing

Go into the configuration dir.

ansible-playbook -i hosts kubernetes.yml -f 6 --private-key=$PRIV_KEY_PATH

Testing and playing around

SSH to the first controller (address in file configuration/hosts) and run

kubectl --kubeconfig /etc/kubernetes/admin.conf get nodes

which should display your ready nodes.

All good things must come to an end

If you want to destroy the cluster just run

terraform destroy

in the provisioning dir.
