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

nodeNetworkCIDRstring
A subnet to use for cluster nodes.
- The IP range must overlap or match the VPC address range.
- The IP range will be evenly split into subnets, one per Availability Zone in your region.
- An optional but recommended parameter. By default, it corresponds to the whole range of VPC addresses.
If a new VPC is created along with a new cluster and no vpcNetworkCIDR is provided, then the range from nodeNetworkCIDR is used for the VPC. Thus, the entire VPC is allocated for the cluster networks, and you will not be able to add other resources to this VPC.

The nodeNetworkCIDR range is distributed between subnets depending on the number of availability zones in the selected region. For example: if nodeNetworkCIDR: "10.241.1.0/20" and there are three availability zones in the region, subnets will be created with the /22 mask.
