Kubernetes Cluster API Provider IBMCloud

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).
