Creating a cluster with Load Balancer and External Cloud Provider - Kubernetes Cluster API Provider IBM Cloud

Provision workload Cluster with Load Balancer and external cloud provider in IBM Cloud VPC

⚠️ WARNING: This feature is currently in experimental stage

Steps

To deploy a VPC workload cluster with Load Balancer IBM external cloud provider, create a cluster configuration with the external cloud provider template
The external cloud provider template will use clusterresourceset and will create the necessary config map, secret and roles to run the cloud controller manager
As a prerequisite set the provider-id-fmt flag with value v2

Change disk size for the boot volume

There are two following variables for controlling the volume size for the boot disk.

IBMVPC_CONTROLPLANE_BOOT_VOLUME_SIZEGIB: Size of the boot volume for the control plane nodes, default set to 20GiB
IBMVPC_WORKER_BOOT_VOLUME_SIZEGIB: Size of the boot volume for the worker nodes, default set to 20GiB

Note: Default value is set to 20GiB because the images published for testing are of size 20GiB(default size in the image-builder scripts as well).
