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-zvirt module in the Deckhouse configuration. Otherwise, if the cluster control plane is hosted in a cloud, the cloud provider uses the ZvirtClusterConfiguration structure for configuration.

ZvirtClusterConfiguration

Version: deckhouse.io/v1

Describes the configuration of a cloud cluster in zVirt.

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 svc/deckhouse-leader -c deckhouse -- deckhouse-controller edit provider-cluster-configuration

After updating the node parameters, you need to run the dhctl converge command to apply the changes.

Example:

apiVersion: deckhouse.io/v1
