hcloud

• Tested Talos version: 1.3.0
• Currently only one control-plane is set up (no HA).
• Number of workers need to be defined in a tfvars file. For an example with three workers see terraform/three_workers.tfvars
• One additional volume is attached to each worker with size specified in the worker_extra_volume_size variable.
• Required patches for OpenEBS Mayastor are applied in templates/controlplanepatch.yaml.tmpl

Prerequisites

# hcloud cli
brew install hcloud
# talosctl, check for latest version https://github.com/siderolabs/talos
sudo curl -Lo /usr/local/bin/talosctl https://github.com/siderolabs/talos/releases/download/v1.3.0/talosctl-$(uname -s | tr "[:upper:]" "[:lower:]")-amd64
sudo chmod +x /usr/local/bin/talosctl
# hashicorp packer
brew tap hashicorp/tap
brew install hashicorp/tap/packer
# hashicrop terraform
brew install hashicorp/tap/terraform

Export your hcloud token:

export HCLOUD_TOKEN=<hcloud-token>

Packer

Create the talos os image via packer. The talos os version is defined in the variable talos_version in hcloud_talosimage.pkr.hcl.

cd packer
packer init .
packer build .
# after completion, export the image ID
export TF_VAR_image_id=<image-id-in-packer-output>

HCloud

cd terraform
terraform init
# example with three worker nodes
terraform plan -var-file=three_workers.tfvars
terraform apply -var-file=three_workers.tfvars

Talosconfig and Kubeconfig

Once terrafrom finished successfully, retrieve talosconfig and kubeconfig from the output.

Example:

terraform output -raw talosconfig > ~/hcloud-dev-cluster/talosconfig
terraform output -raw kubeconfig > ~/hcloud-dev-cluster/kubeconfig
export TALOSCONFIG=~/hcloud-dev-cluster/talosconfig
export KUBECONFIG=~/hcloud-dev-cluster/kubeconfig
# check if all nodes are available, target the control plane (default 10.0.0.3 set in variables.tf)
talosctl get members -n 10.0.0.3
# check nodes
kubectl get nodes -o wide
