AzureClusterConfiguration

Version: deckhouse.io/v1

Describes the configuration of a cloud cluster in Azure.

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.
