Two layouts are supported. Below is more information about each of them.
Standard
- A separate VPC with Cloud NAT is created for the cluster.
- Nodes in the cluster do not have public IP addresses.
- Public IP addresses can be allocated to master and static nodes:
- In this case, one-to-one NAT is used to translate the public IP address to the node’s IP address (note that CloudNAT is not used in such a case).
- If the master does not have a public IP, then an additional instance with a public IP (aka bastion host) is required for installation tasks and accessing the cluster.
- Peering can also be configured between the cluster VPC and other VPCs.
Example of the layout configuration:
apiVersion: deckhouse.io/v1
kind: GCPClusterConfiguration

peeredVPCs:
# Optional, list of GCP VPC Networks with which Kubernetes VPC Network will be peered.

WithoutNAT
- A dedicated VPC is created for the cluster; all cluster nodes have public IP addresses.
- Peering can be configured between the cluster VPC and other VPCs.
