Fields

drainNatIps

Optional

list (object)

drainNatIps[]

Optional

object

A list of IP resources to be drained. These IPs must be valid static external IPs that have been assigned to the NAT.

drainNatIps[].external

Optional

string

Allowed value: The `selfLink` field of a `ComputeAddress` resource.

enableDynamicPortAllocation

Optional

boolean

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.

enableEndpointIndependentMapping

Optional

boolean

Specifies if endpoint independent mapping is enabled. This is enabled by default. For more information see the [official documentation](https://cloud.google.com/nat/docs/overview#specs-rfcs).

icmpIdleTimeoutSec

Optional

integer

Specifies the desired filtering of logs on this NAT. Possible values: ["ERRORS_ONLY", "TRANSLATIONS_ONLY", "ALL"].

maxPortsPerVm

Optional

integer

minPortsPerVm

Optional

integer

Minimum number of ports allocated to a VM from this NAT.

natIpAllocateOption

Required

string

How external IPs should be allocated for this NAT. Valid values are 'AUTO_ONLY' for only allowing NAT IPs allocated by Google Cloud Platform, or 'MANUAL_ONLY' for only user-allocated NAT IP addresses. Possible values: ["MANUAL_ONLY", "AUTO_ONLY"].

natIps

Optional

list (object)

natIps[]

Optional

object

NAT IPs. Only valid if natIpAllocateOption is set to MANUAL_ONLY.

Optional

string

Name of the referent. More info: https://kubernetes.io/docs/concepts/overview/working-with-objects/names/#names

natIps[].namespace

Optional

string

Namespace of the referent. More info: https://kubernetes.io/docs/concepts/overview/working-with-objects/namespaces/

region

Required

string

Immutable. Region where the router and NAT reside.

resourceID

Optional

string

Immutable. Optional. The name of the resource. Used for creation and acquisition. When unset, the value of `metadata.name` is used as the default.

Required

object

The Cloud Router in which this NAT will be configured.

routerRef.external

Optional

string

Allowed value: The `name` field of a `ComputeRouter` resource.

routerRef.name

Optional

sourceSubnetworkIpRangesToNat

Required

string

How NAT should be configured per Subnetwork. If 'ALL_SUBNETWORKS_ALL_IP_RANGES', all of the IP ranges in every Subnetwork are allowed to Nat. If 'ALL_SUBNETWORKS_ALL_PRIMARY_IP_RANGES', all of the primary IP ranges in every Subnetwork are allowed to Nat. 'LIST_OF_SUBNETWORKS': A list of Subnetworks are allowed to Nat (specified in the field subnetwork below). Note that if this field contains ALL_SUBNETWORKS_ALL_IP_RANGES or ALL_SUBNETWORKS_ALL_PRIMARY_IP_RANGES, then there should not be any other RouterNat section in any Router for this network in this region. Possible values: ["ALL_SUBNETWORKS_ALL_IP_RANGES", "ALL_SUBNETWORKS_ALL_PRIMARY_IP_RANGES", "LIST_OF_SUBNETWORKS"].

subnetwork

Optional

list (object)

One or more subnetwork NAT configurations. Only used if 'source_subnetwork_ip_ranges_to_nat' is set to 'LIST_OF_SUBNETWORKS'.

subnetwork[]

Optional

object

subnetwork[].secondaryIpRangeNames

Optional

Status

Schema

conditions:
- lastTransitionTime: string
  message: string
  reason: string
  status: string

observedGeneration: integer
Fields
conditions

list (object)

Conditions represent the latest available observation of the resource's current state.

conditions[]

object

conditions[].lastTransitionTime

string

Last time the condition transitioned from one status to another.

conditions[].message

string

Human-readable message indicating details about last transition.
