# Filename of original vendor's OS image to be used for all the nodes.
# MUST be present under current directory, must be an uncompressed image (not
# img.xz).
# Example:
#IMAGE=ubuntu-26.04.1-preinstalled-server-arm64+raspi.img
IMAGE=

#K8S version to use
K8S_VERSION=1.37.1

#While not mandatory, it is a good idea to have a DNS name or at least a fixed
#IP-address associated with your master's MAC address. Otherwise, when your
#master's address changes, you will have to manually rejoin all nodes to master
#at its new IP.
#IMPORTANT: the DNS and/or IP address must be assigned to the master BEFORE
#the node is first bootstrapped.
#Example:
#CONTROL_PLANE_ENDPOINT="cluster.local"
CONTROL_PLANE_ENDPOINT=

#TTL of kubeadm's bootstrap token used by nodes to initially join the cluster.
#Set to 0 to never expire.
#Example: TOKEN_TTL="24h0m0s".
TOKEN_TTL=0

#IP prefix for all pods in the Kubernetes cluster. This range must not overlap
#with other prefixes on your local network.
POD_NETWORK_CIDR="172.30.0.0/16"

# CNI to use, "calico", "weave" of "flannel". Only calico seems to work out of 
# the box for all uses. Flannel has issues that have not been resolved
# yet and might not work for you. Weave net has changed its installation process
# and is therefore broken now.
CNI_TYPE="calico"
#Use specific calico version (no "v" prefix).
#By default, v3.25.1 is used if the variable is not set.
#CALICO_VERSION="3.25.1"

#A command for the nodes to join master. When a master node is bootstrapped,
#it will be written to file /usr/lib/k8r/join_string . You need to set it as
#a value here before building an image for worker nodes.
KUBEADM_JOIN_STRING=""

#Optional setting to point the nodes to an HTTP repo where node images are
#stored. This is used for online upgrade process.
# Example:
#HTTP_IMAGE_URL="http://1.1.1.1:2080/k8r_images/$K8S_VERSION/images/"
HTTP_IMAGE_URL=

#Optional setting to make the nodes use some docker registry without encryption
#and authentication. Useful if you have a private registry on your network.
# Example:
#INSECURE_REGISTRY="1.1.1.1:5000"
INSECURE_REGISTRY=
