Fields

action

Required*

string

The Action to perform when the client connection triggers the rule. Valid actions are "allow", "deny" and "goto_next".

description

Optional

string

An optional description for this resource.

direction

Required*

string

The direction in which this rule applies. Possible values: INGRESS, EGRESS

disabled

Optional

boolean

Denotes whether the firewall policy rule is disabled. When set to true, the firewall policy rule is not enforced and traffic behaves as if it did not exist. If this is unspecified, the firewall policy rule will be enabled.

enableLogging

Optional

boolean

Denotes whether to enable logging for a particular rule. If logging is enabled, logs will be exported to the configured export destination in Stackdriver. Logs may be exported to BigQuery or Pub/Sub. Note: you cannot enable logging on "goto_next" rules.

firewallPolicyRef

Required*

object

Immutable.

firewallPolicyRef.external

Optional

string

A reference to an externally managed ComputeFirewallPolicy resource. Should be in the format `locations/global/firewallPolicies/`.

firewallPolicyRef.name

Optional

string

The `name` field of a `ComputeFirewall olicy ` resource.

firewallPolicyRef.namespace

Optional

string

The `namespace` field of a `ComputeFirewallPolicy ` resource.

match

Required*

object

A match condition that incoming traffic is evaluated against. If it evaluates to true, the corresponding 'action' is enforced.

match.destAddressGroups

Optional

list (string)

Address groups which should be matched against the traffic destination. Maximum number of destination address groups is 10. Destination address groups is only supported in Egress rules.

match.destAddressGroups[]

Optional

string

match.destFqdns

Optional

list (string)

Domain names that will be used to match against the resolved domain name of destination of traffic. Can only be specified if DIRECTION is egress.

match.destFqdns[]

Optional

string

match.destIPRanges

Optional

list (string)

CIDR IP address range. Maximum number of destination CIDR IP ranges allowed is 256.

match.destIPRanges[]

Optional

string

match.destRegionCodes

Optional

list (string)

The Unicode country codes whose IP addresses will be used to match against the source of traffic. Can only be specified if DIRECTION is egress.

match.destRegionCodes[]

Optional

string

match.destThreatIntelligences

Optional

list (string)

Name of the Google Cloud Threat Intelligence list.

match.destThreatIntelligences[]

Optional

string

match.layer4Configs

Required*

list (object)

Pairs of IP protocols and ports that the rule should match.

match.layer4Configs[]

Required*

object

match.layer4Configs[].ipProtocol

Required*

string

The IP protocol to which this rule applies. The protocol type is required when creating a firewall rule. This value can either be one of the following well known protocol strings (`tcp`, `udp`, `icmp`, `esp`, `ah`, `ipip`, `sctp`), or the IP protocol number.

match.layer4Configs[].ports

Optional

list (string)

An optional list of ports to which this rule applies. This field is only applicable for UDP or TCP protocol. Each entry must be either an integer or a range. If not specified, this rule applies to connections through any port. Example inputs include: ``.

match.layer4Configs[].ports[]

Optional

string

match.srcAddressGroups

Optional

list (string)

Address groups which should be matched against the traffic source. Maximum number of source address groups is 10. Source address groups is only supported in Ingress rules.

match.srcAddressGroups[]

Optional

string

match.srcFqdns

Optional

list (string)

Domain names that will be used to match against the resolved domain name of source of traffic. Can only be specified if DIRECTION is ingress.

match.srcFqdns[]

Optional

string

match.srcIPRanges

Optional

list (string)

CIDR IP address range. Maximum number of source CIDR IP ranges allowed is 256.

match.srcIPRanges[]

Optional

string

targetResources[]

Optional

object

targetResources[].external

Optional

string

A reference to an externally managed Compute Network resource. Should be in the format `projects//global/networks/`.

targetResources[].name

Optional

string

The `name` field of a `ComputeNetwork` resource.

targetResources[].namespace

Optional

string

The `namespace` field of a `ComputeNetwork` resource.

targetServiceAccounts

Optional

list (object)

- lastTransitionTime: string
  message: string
  reason: string
  status: string
  type: string

kind: string
observedGeneration: integer
ruleTupleCount: integer
Fields
conditions

list (object)

Conditions represent the latest available observations of the object's current state.
conditions[]

object
conditions[].lastTransitionTime

string

Last time the condition transitioned from one status to another.
conditions[].message

string
