description="OpenStack region (VK Cloud typically has a single region, \"RegionOne\" - not to be confused with availability zones like \"ME1\"/\"MS1\")"
description="OpenSSH public key content to register as the ssh_key_name keypair under the deploying account (Nova keypairs are per-user, not per-project - a key uploaded under a different account is invisible here). Leave null if a keypair with that name already exists under the deploying account."
description="Explicit CIDR prefix for each project-managed private network that router VMs get an interface into (Terraform creates the network/subnet, Neutron IPAM assigns the address). One entry = one shared private network = one private interface per router. Optional - leave empty ([]) for a deployment that only uses var.router_networks (pre-existing externally-owned networks) for its private interfaces."
description="Pre-existing private networks (typically owned by a different VK Cloud project, referenced by UUID only - not managed by this Terraform) that each router VM gets a fixed-IP interface into. Map key = role/interface name (e.g. \"primary\"/\"backup\"); ip_addresses[i] is the address for router(i+1). Optional - leave empty ({}) for a deployment that only uses var.private_network_cidrs for its private interfaces."
description="Explicit override for the project's 'default' security group UUID. Last resort only - by default it's resolved dynamically via data.vkcs_networking_secgroup (see main.tf), since this UUID is unique per project and must not be hardcoded."
