# Setup talos cluster

This will not be perfect, it's for my own use and for learning :)

 ## Target
 * running talos with defined number of controlplanes/workers
 * install Hetzner Cloud Controller Manager
 * install Cilium with Gateway API

Configured correctly and Hetzner has no issues, talos + kubernetes is up and runing in about 5 minutes.

 ## Requirements
 * Hetzner customer :)
 * Domain at Hetzner, not needed, can be removed/adapted
 * packer for creating a talos base image
 * tofu (Should work with terraform too)
 * I use direnv to setup all the needed configuration variables

## Config

### Required environment variables:

```
# to use hcloud command in shell, optional
export HCLOUD_TOKEN=....
# for provider setup
export TF_VAR_hcloud_token=$HCLOUD_TOKEN

# provider setup
export HETZNER_DNS_API_TOKEN=...

# not needed, but useful when used with direnv in .envrc file
# tofu output -raw kubeconfig >kubeconfig; tofu output -raw talosconfig >talosconfig
export KUBECONFIG=kubeconfig
export TALOSCONFIG=talosconfig

```

### Input Parameter

see test.tfvars.sample

## Todo
* define kubernetes version to be installed
* define cilium version to be installed (hardcoded to 1.16rc right now)
* maybe some other tweaks
* maybe instsall flux, not sure if that should be part of initial setup
