# 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".

hcloud_token = "xxxxxxxxxxxxxxxxxxYYYYYYYYYYYYYYYYYYYzzzzzzzzzzzzzzzzzzzzz"
# * Your public key
public_key   = "/home/username/.ssh/id_ed25519.pub"

# As per rancher docs, it must be always an odd number, never even! See https://rancher.com/docs/k3s/latest/en/installation/ha-embedded/

# 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 [] or just set the counts to 0.
