Key	Description
`vpc`	The name of the VPC assigned to the cluster.
`network.public`	If `true`, the VPC is publicly exposed to the internet.
`network.internalLbCIDRs`	List of CIDRs for internal load balancers in the cluster, reachable from within the VPC.
`network.podCIDR`	List of CIDRs for the Pods in the cluster.
`network.serviceCIDR`	List of CIDRs for the Services in the cluster.

An example CKS cluster manifest is shown below. The highlighted values in the network block define the VPC's configuration.
