Define the cluster hosts and infrastructure
Konvoy needs to know how to access your cluster hosts. This is done using inventory resources. For initial cluster creation, you must define a control-plane and at least one worker pool.
Define your Infrastructure
Export the following environment variables, ensuring that all control plane and worker nodes are included:CODE
export CONTROL_PLANE_1_ADDRESS="<control-plane-address-1>" export CONTROL_PLANE_2_ADDRESS="<control-plane-address-2>" export CONTROL_PLANE_3_ADDRESS="<control-plane-address-3>" export WORKER_1_ADDRESS="<worker-address-1>" export WORKER_2_ADDRESS="<worker-address-2>" export WORKER_3_ADDRESS="<worker-address-3>" export WORKER_4_ADDRESS="<worker-address-4>" export SSH_USER="<ssh-user>" export SSH_PRIVATE_KEY_SECRET_NAME="$CLUSTER_NAME-ssh-key"
Use the following template to help you define your infrastructure. The environment variables that you set in the previous step automatically replace the variable names when the inventory YAML file is created.CODE
cat <<EOF > preprovisioned_inventory.yaml --- apiVersion: infrastructure.cluster.konvoy.d2iq.io/v1alpha1 kind: PreprovisionedInventory metadata: name: $CLUSTER_NAME-control-plane namespace: default labels: cluster.x-k8s.io/cluster-name: $CLUSTER_NAME clusterctl.cluster.x-k8s.io/move: "" spec: hosts: # Create as many of these as needed to match your infrastructure # Note that the command line parameter --control-plane-replicas determines how many control plane nodes will actually be used. # - address: $CONTROL_PLANE_1_ADDRESS - address: $CONTROL_PLANE_2_ADDRESS - address: $CONTROL_PLANE_3_ADDRESS sshConfig: port: 22 # This is the username used to connect to your infrastructure.
