Support for Dynamic Port Allocation

[alexander-verharen-qc]

TL;DR

Google and Terraform support dynamic port allocation, while this module does not yet support it.

The following new variables are needed:

max_ports_per_vm - (Optional) Maximum number of ports allocated to a VM from this NAT. This field can only be set when enableDynamicPortAllocation is enabled.

enable_dynamic_port_allocation - (Optional) Enable Dynamic Port Allocation. If minPortsPerVm is set, minPortsPerVm must be set to a power of two greater than or equal to 32. If minPortsPerVm is not set, a minimum of 32 ports will be allocated to a VM from this NAT config. If maxPortsPerVm is set, maxPortsPerVm must be set to a power of two greater than minPortsPerVm. If maxPortsPerVm is not set, a maximum of 65536 ports will be allocated to a VM from this NAT config. Mutually exclusive with enableEndpointIndependentMapping.

Terraform Resources

https://registry.terraform.io/providers/hashicorp/google/latest/docs/resources/compute_router_nat#enable_dynamic_port_allocation

Detailed design

enableDynamicPortAllocation can only be set to true if enableEndpointIndependentMapping is false.

Additional information

Google provider version 4.5 or greater
