If the cluster control plane is hosted on a virtual machines or bare-metal servers, the cloud provider uses the settings from the
cloud-provider-vcd
module in the Deckhouse configuration. Otherwise, if the cluster control plane is hosted in a cloud, the cloud provider uses the VCDClusterConfiguration structure for configuration.
VCDClusterConfiguration
Version: deckhouse.io/v1
Describes the configuration of a cloud cluster in VCD.
Used by the cloud provider if a cluster’s control plane is hosted in the cloud.
Run the following command to change the configuration in a running cluster:
kubectl -n d8-system exec -ti deploy/deckhouse -- deckhouse-controller edit provider-cluster-configuration
Example:
apiVersion: deckhouse.io/v1
kind: VCDClusterConfiguration
