# Only the first values starting with a * are obligatory, the rest can remain with their default values, or you
# could adapt them to your needs.
#
# Note that some values, notably "location" and "public_key" have no effect after the initial cluster has been setup.
# This is in order to keep terraform from re-provisioning all nodes at once which would loose data. If you want to update,
# those, you should instead change the value here and then manually re-provision each node one-by-one. Grep for "lifecycle".

# * Your Hetzner project API token 
hcloud_token = "xxxxxxxxxxxxxxxxxxYYYYYYYYYYYYYYYYYYYzzzzzzzzzzzzzzzzzzzzz"
# * Your public key
public_key   = "/home/username/.ssh/id_ed25519.pub"
# * Your private key, must be "private_key = null" when you want to use ssh-agent, for a Yubikey like device auth or an SSH key-pair with passphrase
private_key  = "/home/username/.ssh/id_ed25519"

# These can be customized, or left with the default values

network_region   = "eu-central" # change to `us-east` if location is ash

# You can have up to as many subnets as you want (preferably if the form of 10.X.0.0/16),
# their primary use is to logically separate the nodes.
# The control_plane network is mandatory.

# At least 3 server nodes is recommended for HA, otherwise you need to turn off automatic upgrade (see ReadMe).
# As per rancher docs, it must be always an odd number, never even! See https://rancher.com/docs/k3s/latest/en/installation/ha-embedded/

# As for the agent nodepools, below is just an example, if you do not want nodepools, just use one,
# and change the name to what you want, it need not be "agent-big" or "agent-small", also give them the subnet prefer.
# For single node clusters set this equal to {}

### The following values are fully optional

# It's best to leave the network range as is, unless you know what you are doing. The default is "10.0.0.0/8".

# If you want to use a specific Hetzner CCM and CSI version, set them below, otherwise leave as is for the latest versions

# Also good for single node clusters.

# If you want to disable automatic upgrade of k3s, you can set this to false, default is "true".

# Adding extra firewall rules, like opening a port
# In this example with allow port TCP 5432 for a Postgres service we will open via a nodeport
